i'm really thank you for this library.
I use it for get data form my keyboard. via USB midi.
I use usb host for arduino, and arduino mega 2560.
when connected, data send not continues, it like a "LAG" for some note, and after few seconds, it tranmist again.
I don't know why is that. Please help me ! thank you !

P/s: when connect keyboard with PC, this work well.

Hello,

Earlier last year, I incorporated UHS2.0 into Marlin. This year I am investigating migrating Marlin to UHS3.0, since we are seeing issues with one of our boards with the old code and I rather put our resources into fixing issues in UHS3.0 rather than UHS2.0. I believe having us chip in development work would be helpful to everyone!

In doing the preliminary work to intergrate UHS3.0, I notice a couple things:

• The code is much cleaner and better organized (this is good!)
• The license is GPL v2, rather than "GPL v3" or "GPL v2 or any later version" (this is a showstopper!)
• When I try compiling with "USB_HOST_SHIELD_USE_ISR 0", I get an error saying this isn't supported (this could present problems with Marlin).

Marlin makes heavy use of interrupts itself and I feel there is much less risk involved if the USB code can run in polled mode. I notice that in "USB_HOST_SHIELD.h" if ARDUINO_AVR_BALANDUINO is defined, it asks the user to use USB_HOST_SHIELD_USE_ISR as 0. So this suggests that at least some work has been done on the feature.

So, a few questions:

1. Could this code be relicensed to "GPL v2 or any later version", so that I can integrate it into Marlin? (which is GPL v3).
2. UHS2.0 worked without an interrupt, how difficult would it be to make UHS3.0 work without it too?
3. How much work has actually been done in working without interrupts? What is the ARDUINO_AVR_BALANDUINO and how does that work without interrupts?

Any help with these questions are very much appreciated! Thank you!

I am making a robotic arm. The controller I am using is a Logitech extreme 3D pro. I was using an Arduino Mega 2560 with the Arduino USB Host Shield to connect to the joystick. In order to get more processing power, I switched to the Arduino Due, which has a native USB port built in. This native port replaces the need for the Arduino USB Host Shield. Because the USB_Host_Shield_2.0 Library is built for the Arduino USB Host Shield ONLY. Because of this, I need something (like this library) than can connect the Logitech Extreme 3D Pro Joystick to the Arduino Due. Is there an example like the one in USB_Host_Shield_2.0?

Hi

now that the lib was restructured with submodules, shouldn't there be a different define for headers only include?

If I #define i.e. LOAD_UHS_KINETIS_FS_HOST both UHS_KINETIS_FS_HOST.h and UHS_KINETIS_FS_HOST_INLINE.h will be included. If I don't define anything, nothing will be included.

So it's not possible to use UHS3 from different source files, i.e. I'd like to put all the USB host stuff in a different source file away from the .ino

Thanks,
Markk

I have been successfully experimenting with a number of USB thumb drives all with a blank label. As expected, the drives mount at "/". I am now attempting to mount a drive with a non blank label such as 'foo'. The drive appears to mount but then reports 0 space available on the drive. With a label of 'foo' on the drive I am passing '/foo' to both 'fs_ready()' and 'fs_getfree()'. I am using 'UHS_FS_NEW_DEMO' as the basis for my tests. I recognize that once the reported free space test passes, the following file names will need to include the mount point '/foo' as well.

I suspect that my understanding of the proper mount points is in error.

In anticipation of mounting multiple drives, I have increased _FS_LOCK from 1 to 4.

Continued thanks for your great work to support UHS30.

We need to make the same fix as in PR: https://github.com/felis/USB_Host_Shield_2.0/pull/185/files.

A quick search shows the relevant files: https://github.com/felis/UHS30/search?utf8=%E2%9C%93&q=epAttribs. I recommend never setting epAttribs explicit to zero, as this will cause bugs if bmNakPower is already set.

Hi there,

I know this is still in development, so forgive me if you are already aware of this.

Testing various MIDI controllers with this library, and I can only get one to work. Looking at the debug for those that don't work (below), it appears that the class doesn't find a compatible library, however these controllers were definitely supported by UHS v2, and are class compliant.

Thanks.

I tried to compile (STM32F103C8T6) but the first error that occurred seems to be relative to the interrupt register definition.

I found this post that might help someone identify that SPI port interrupt register:

https://os.mbed.com/forum/mbed/topic/26688/?page=1#comment-50909

Maybe it will be interesting for some MBED developers.

I explain how to extend the SPISlave class for use interrupts on STM32 MCU. With this solution we do not need to change anything in the basic SPISlave class.

First step is common and strighforward. We create instance of SPISlave class and do some configuration (format, frequency, ...). Next we setup SPI CR2 register to enable interrupts. Especially:

• TXEIE bit to enable 'Tx buffer empty' interrupt - RXNEIE bit to enable 'RX buffer not empty' interrupt

and at last we install own ISR routine for SPI interrupts.

Some explanaition.

Because SPI work in full duplex mode we must have 'filler' (empty) character. I use null byte as filler. Send or receive null byte means that there is nothing to send (or receive). As a consequence this protocol cant be used for binary data. Null bytes must be encoded/decoded on both side (escape sequence processing).

My ISR routine cooperate with two buffers and simple API: - saveInBuf save received characters in external buffer - char2send get next byte to send from transmit buffer

Local (static) buffer 'intBuf' is used in the case when main receive buffer is (temporarily) in use and received character can't be saved.

I run test program on Nucleo-STM32F103RB (64 MHz HSI) connected to Orange Pi Lite (Armbian Linux). On Orange Pi side I use two transmission buffers and Timer interrupt to check for pending transmission (once per 100 us). I configure SPI on both side in 8 bit mode and 16 Mhz frequency.

I'm trying to connect USB host shield with the device having FTDI Chip to provide virtual com port. But failed to build a connection between host and device. I'm using USB host library 2.0 available on GitHub.
Does anyone knows how to Implement FTDI on this library??
Some device specs are listed below:
VIRTUAL COM PORT
Baud Rate:9600 baud* Format: 8 data bits, no parity, 1 stop bit*
Protocol: Modbus over Serial Line

I am building a datalogger whose primary memory is the SD card and the secondary storage is the USB flash drive. The data in the SD card is downloaded into the USB flash drive like once a week. I am using Arduino Mega ADK with Max3421 USB host chip.

1. How can I use both SD card and Flash Drive together. The excellent UHS30 library seems to conflict with SD.h, SdFat.h and Fatfs.h(to a limited extent).

Any example code will do, especially to be able to initialize and mount the SD card and write/read text files. CS on my SD card shield is on digital pin 8 (cs_pin=8) of my Arduino board.
2. I have some success with the SD card datalogger separately and UHS20 separately. UHS30 compiles on Arduino 1.6.9, AVR board 1.6.11, Windows 7 but it wouldn't execute any function (blank). Only UHS20 works for now.

Hello - I am attempting to run the UHS30 library on a MKRZero (SAMD21 based) arduino board, connected to a UHS2.0 (mini MAX3421E based shield). My goal is to have a USB keyboard plugged into the mini-shield and continue to use the standard usb port on the arduino as a serial connection back to a host computer.

I guess my first question is whether this should be a supported configuration, should the UHS30 library be able to run in parallel with the 'standard' usb(device) support provided by the platform?

Assuming that is a reasonable goal - I started digging into the UHS30 libraries and have discovered that it appears the MKRZero isn't a supported processor right out of the box. Ok, I've recently setup this exact same scenario using the USB_Host_Shield_2.0 library and was able to modify that lib to work with MKRZero (although that required renaming a couple of the lib's classes, so not a pretty port) so decided I'd give porting this lib to the new board a shot... Since the original Arduino Zero appears to be supported I figured it shouldn't be that bad. I found the few places that ifdefs looked for "ARDUINO_SAMD_ZERO" and added "ARDUINO_SAMD_MKRZERO" as appropriate. I think I've managed to do this (close to) correctly (since the code compiles without complaints from the compiler/linker). However, after being flashed to the board something is keeping the native usb port from initializing correctly (the host PC isn't seeing it as a Serial port any longer and reports "Device Descriptor Request Failed"...
I'm using USB_HID_KB_MOUSE.ino as the main sketch (although I am using Eclipse as my dev environment, so the sketch has been turned into a .cpp file). Since the serial port back to the host isn't working, I'm not getting any debug output, but by commenting out lines of code I've manged to determine that it's the instantiation of the UHS_HID classes that appears to be causing the problem...
'''
UHS_HID hid1(&UHS_Usb, &HID_processor1);
UHS_HID hid2(&UHS_Usb, &HID_processor2);
'''

I'm instantiating the MAX3421E_HOST with (what I believe to be) the proper pins called out for SS and INT (4 and 5 in my case). SPI pins are the defaults of 9(SCK), 8(MOSI) and 10(MISO).

I realize that this library is explicitly stated as not having technical support, but I was hoping to be able to at least contribute back changes to support the MKRZero board (if I can get it working).
Any pointers on where to look for what may be causing the issue would be greatly appreciated.
Thanks.

Again, sorry if this is a known issue, but I cannot find another issue discussing it.

I have modified the USB_MIDI_Dump demo to use two hubs and two midi devices.
I find that a single device works well through a hub, but creating a second midi device stops it working. It compiles, but doesn't connect to or receive data from either MIDI device once more than one is declared.

Many thanks,

Hello,

I would like to recommend adding additional header and introduction comments/documentation for the UHS_FS_NEW_DEMO.ino example.

Full path to file:
UHS30/libraries/UHS_FS/examples/USB_HOST_SHIELD/UHS_FS_NEW_DEMO/UHS_FS_NEW_DEMO.ino

I am currently adapting UHS30 to use a USB thumb drive as a flash storage device as a file system for my Project.

While reading the example code and trying to compile and deploy the example, it took me several days to fully understand the importance of defining the Volume Label correctly. Until the VOL_LABEL matched what the usb drive had, the demo would not work correctly.

I would like to recommend adding extra emphasis at the top of the header for this example to underscore and really highlight the essential importance of this configuration step. This is of particular value to new users who may not be as familiar with debugging code and just want to get up-and-running as quickly as possible. Here is my suggestion addition to the header comment:

// ******* IMPORTANT ******* READ THIS FIRST !
// You MUST define the VOL_LABEL correctly to match what is on your USB Device, or else
// the call to mount the USB mass storage volume will not succeed and this demo will fail to run
// properly and will fail to recognize the volume.
// On Windows, volume labels may be defined at the Command Line by the command label.
// On MacOS, volume labels may be changed using /usr/sbin/diskutil rename
// On Linux, volume lablels may be changed using mlabel or e2label

// define the label of your filesystem. VOL_PATH must end in '/'
// Example:
// #define VOL_LABEL "/foo"
// #define VOL_PATH "/foo/"

#define VOL_LABEL "/"
#define VOL_PATH "/"`

Also: suggest adding a possible solution to the Print Statement:

printf_P(PSTR("No media. Waiting to mount. Check VOL_LABEL is defined to match USB drive. " VOL_LABEL "\r\n"));

Thank you.

What would be the best way to implement subj.? I'm coding pic32 hal, there is a compiler macro for that so I can just use it. Another way is to define it like it's done in swi. Yet another way is to reserve a name and have a func with this name for every arch - this will be beneficial if we ever decide to remove more code from the hal into generic.

Hi

Hi

I am trying to run acm_terminal together with a Huawei USB modem. However, I am getting the following output in the serial window.

I modified the Setup a bit, as follows

void setup() {
Serial.begin( 115200 );
delay(1000);
Serial.print("Start\r\n");
while(!USB_HOST_SERIAL);
USB_HOST_SERIAL.begin(115200);
Serial.print("USB HOST SERIAL True\r\n");

    printf_P(PSTR("\r\n\r\nStarting CDC-ACM test program...\r\n"));
    while(UHS_Usb.Init(1000) != 0);
    printf_P(PSTR("\r\n\r\nWaiting for Connection...\r\n"));

}

What may be causing this issue?

Also, as you can see there seems to be some issue with the printf_P function, as I am not getting that output.

I have included all the defines in the code.

// Patch printf so we can use it.
#define LOAD_UHS_PRINTF_HELPER 1
#define ENABLE_UHS_DEBUGGING 1
#define DEBUG_PRINTF_EXTRA_HUGE 1
#define DEBUG_PRINTF_EXTRA_HUGE_UHS_HOST 1
#define DEBUG_PRINTF_EXTRA_HUGE_USB_HOST_SHIELD 1

What could be the issue here?

Thanks, Thomas

Please review the UHS_HID_interface struct.
Lets make sure it covers most of what we will need to pass onto a hid USB driver.
One thing at a time here too. We can add stuff later on for BT.

I tried commenting out the following line.
https://github.com/felis/UHS30/blob/master/libraries/UHS_host/UHS_host_INLINE.h#L764-L766

                        if(!ei->interface.numep) {
//                                rcode = getone(pep, left, read, data, offset);
//                                if(rcode)
//                                        return rcode;
                        }

It's work fine.

Am I wrong? or correct?

Hi,
I would like to try this out! I am currently using the USB Host 2.0 library with Android ADK and am finding issues with the Usb.Task(). I think an interrupt based usb host would work better.

Is there a UHS3.0 example that would work with ArduinoBlinkLED for Android, like there is for the UHS2.0? If not, any other examples that work with ADK?

Thanks!

Hi,

I'm trying to use UHS_MIDI to connect an Arturia Beatstep Pro which is not working.
It seems to find and connect the device, but as soon as any data from the device arrives it just disconnects the device...

Hi,

my project is based on your code, thus I think maybe you have this problem too.

once every ~20-30 insertions the peripheral returns hrNAK in rHRSL without flipping JSTATUS or KSTATUS in busprobe().

the commit from rodan/lemidi@708f794#diff-15d89ed0b4fc434be8c03517072a6efa fixed that problem for me.

if you have the Logic software from Saleae you can check out the problem
https://github.com/rodan/lemidi/blob/master/qa/wrong_init.logicdata
and after the patch
https://github.com/rodan/lemidi/blob/master/qa/fix_wrong_init.logicdata

might help, might not, thought I'd share either way.

cheers,
peter

Possible bug:
https://github.com/felis/UHS30/blob/master/libraries/UHS_KINETIS_FS_HOST/UHS_KINETIS_FS_HOST_INLINE.h#L348

In PIC32 which is likely based on the same SIE this bit means 'reset' in device mode and 'detach' in host mode (that's our mode of interest). Xxxajk - please confirm or deny.

Any idea?

Hi all, I was looking to use the library as a starting point to getting the CH340/341a serial chip as one of the supported serial coms devices, anyone know if any of the already done ftdi or prolific would be a good jumping off point? I have been sniffing the usb packets on wireshark and it all looks fairly tame.

I am trying to run the UHS_FS_NEW_DEMO on an Tosduino MEGA 2560 (Arduino Mega compatible) with an Arduino USB Host Shield and it seems to crash during Init_Generic_Storage(&UHS_Usb);, as shown by this screen shot:

One of our engineers had made a small modification to the RESET pin of the Arduino shield, so I had to add the following bit of code to the start of the sketch:

void setup() {
  // MAX3421 reset pin on D7
  pinMode(7, OUTPUT);
  digitalWrite(7, LOW);
  delay(100);
  digitalWrite(7, HIGH);
  delay(100);
  ...
}

I presume this won't cause a problem, but I thought I would mention it, just in case. I'll try narrowing down where in Init_Generic_Storage the crash is happening.

Anybody actively using / working this UHS?
Like to discuss some issues, but if there is nobody home, why bother.
Please reply first.

I failed to build a connection between USB host Shield and My Device. I'm using USB host library 2.0 and USH30 in that i have used CDC_ACM as well which is available on GitHub.
Could You please help me out I am totally new in this.

My device specs are listed below:
VIRTUAL COM PORT
Device Type: Ports (COM & LPT)
Manufacturer: FTDI
Location: on USB Serial Converter
Baud Rate:115200 baud* Format: 8 data bits, no parity, 1 stop bit*
Device Description : USB Serial Port
USB Device Hardware Ids: FTDIBUS\COMPORT&VID_0403&PID_6015

When I upload USBFTDILoopback.ino It won't give any response just print "Start", Please refer below screenshot

And in acm_terminal.ino it prints in Serial Monitor "waiting for connection....", Please refer below screenshot

Hi,
I have a USB HID device that I would like to connect directly to the Native USB port of my DUE. I know what data to expect and what data to send, but I don't know how to approach this problem. Is it at all possible to use this library for that purpose without the USB shield? Do I need to implement my own driver and if so, is there any example for doing this? Thanks for your help.

I acknowledge that there is no technical support available for UHS30 at this time.

I have indeed committed to the use of UHS30 for a project. Thus far, I have been utilizing the UHS_FS_NEW_DEMO to test the mounting and access to a thumb drive. The test seems to run for days suggesting that the current UHS30 code is reliable.

I am just about to begin developing the real application which will include a few sensors and two USB thumb drives and a SD memory card. The SD card is intended to be the primary data storage location with the two USB devices available for a user to periodically swap.

My use of UHS30 thus far has been via Arduino IDE version 1.6.5. I have as well successfully built the test applications using the Visual Micro plugin for Atmel Studio 6.2. While both environments seem to work, my desire is to shift development to Atmel Studio 6.2 w/o the use of the Visual Studio plugin.
I have created a core library from the Arduino 1.6.5 IDE and libraries for all of the non UHS30 Arduino libraries that are necessary when using the IDE or Visual Micro. I seem to be having some difficulty in creating a standalone UHS30 library within Visual Studio.

I am looking for some advice or recommendations regarding my plan to shift to the use of Visual Studio.

My current strategy in attempting to create a UHS30 library is actually to create individual libraries for each of the directories within the UHS30\library structure. This may indeed be problematic.

Any thoughts, feedback or advice would be greatly appreciated.

Regards,
-marc

This is a follow-up to a discussion between me and xxxajk about the subj. I commented out Release() from bulk_storage and verified by running UHS_FS_NEW_DEMO. See 077dca3

xxxajk pls take a look

Greetings to the authors of this library.

First of all, thank you for taking the time and efforts to create a promising library!

Please forgive me if this post is a bit premature for this library, however I hope that one may confirm or deny if this library is the right library for what I wish to achieve.

What I am trying to achieve:-
I am currently working on a project that uses nearly every single pin header available on a Due, including all hardware serial ports and I would like to use the native USB port on the Due's to communicate between each other.

I understand that it is possible to setup one Due as a USB client serial device by invoking the SerialUSB.begin(9600); command and then sending data using SerialUSB.println("Hello World");
When connected to my PC or connected to my android phone using a OTG cable with the phone as a host, it works a treat.

As such I would require to setup the master Due as a USB host with an OTG cable to accept the CDC? connection/device that is the slave Due and to be able to read the serial data using SerialUSB.read();

It would appear that all the serial communication commands are there already, however I am struggling to get the Host Due to open a serial port with the slave Due.

My Question:-
Is this library, in its current form, possible to achieve what I am wishing to?
I have downloaded it and have played with it some, however I am not familiar with setting up the native USB host on the Due so my efforts have been to no avail thus far.

If the library does not currently support this type of connectivity, is this something that is planned for this library in the future?

Again many thanks for your time and effort with this library as I foresee it opening the doors to all sorts of cool project ideas!

I understand this project is not yet in a position to start providing technical support, as mentioned on the home page, however if you can provide any pointers that would get me a step closer to my goals it would be hugely appreciated.

Many thanks.
Delphi.

Hi

this lib sounds great! Thank you for your efforts!

I try to compile KINETIS_DEV_DESC on a Teensy 3.1 but I get this error:

mlock.c:27:2: error: #error "No Barrier implementation"

If I track things correctly, it should probably include dyn_SWI.h. However if the latter is included compilation fails because dyn_SWI.h contains C++ stuff while mlock.c is C only.

I'm afraid I need a hint to explore this further... or am I too early to try this?

Thanks for all help!

Hi everyone!

I'm using my arduino uno with my UHS to make communication with a HID-Device (DataLogger). I'm thinking the UHS_HID_RAW example sketch could be useful for my project. Has anyone some information how can i send and receive data with that sketch?

I've found that running an Arduino sketch with UHS3 and the Arduino Servo library causes the servo to twitch. This is one of the problems I am encountering in integrating UHS3 into our printers.

However, since this isolates the problem better, limiting it to the interaction of two libraries, I figured I would pass the information along.

I am looking for an example of how to leverage writeReport.
Specifically, I'm trying to send a query string which should illicit a response with the requested information.
It doesn't appear to send the query string out though;

d->writeReport(uint16_t(sizeof(upsquery1))-1, uint8_t(upsquery1));

I assume I'm doing something wrong and seeking a functional example(s) of writeReport.

The sketch I'm working with is below.

It would be very interesting to be able to use this library with ESP32. This Teensy is very expensive.

Does anyone know if there is already an example?

I'm trying to use STM32F4 with two internal USB Host (OTG). But this library is still the best alternative for compatibility with the mini keyboard, with touchpad.

ATM they come from Arduino tree and apart from hw-specific code they are called from the core as well as swi (see grep output below). PIC32 won't be able to use it. What would be the best course of action - abstract it out somewhere else, perhaps?

I am testing MIDI driver with MEGA ADK.
malloc() and new fail in the AVR toolchain after version 1.6.12.

• Work: 1.6.2 to 1.6.11
• Not work: 1.6.12 to 1.6.20

However, in version 1.6.11 or earlier, UNO will result in a link error.

This is a continuation of the issue raised on ush2 with accessing a mass storage device using a usb host shield and a teensy 3.5. By the way its a microcent 8gb thumb drive. I incorporated the suggestions in the last post:

#define UHS_DEVICE_WINDOWS_USB_SPEC_VIOLATION_DESCRIPTOR_DEVICE 0

// Uncomment to debug
#define ENABLE_UHS_DEBUGGING 1
// Uncomment to make debugging very noisy
#define DEBUG_PRINTF_EXTRA_HUGE 1

and still hangs. I am attaching a text file with the debug messages for your reference.

UPDATE: Fiddling around with the FS_lock parameter, changed it to around 1000 and it seemed to running even further. On the off chance that there is some sort of propotional time affect on the sketch with the number of files on the drive I decided to delete all files on the drive and put just 5 files on it for a test.

With a FS_lock of one I get a repeating error:

ResetRecovery

Gen SCSI Err: 27
LUN: 00

Read LUN:

CBW.dCBWTag: 00000032
USB Error: 06
Index: 01
CBW: OK
Data Stage: OK
CSW:Sig error
Invalid CSW

where the TAG keeps incrementing. Changing it to 255 it proceeds further with periodic error messages like above - gets to CBW.dCBWTag: 00000ADE hangs for awhile then it gives me a few more USB errors and SCSI errors and continues very slowly. Increasing it makes it worse like for FS_lock 1.

Hope this info helps
