Help to move data between SD Card & USB flash Drive with UHS30 or UHS20 about uhs30 HOT 92 CLOSED

first important part from the example:
https://github.com/felis/UHS30/blob/master/libraries/UHS_FS/examples/USB_HOST_SHIELD/UHS_FS_NEW_DEMO/UHS_FS_NEW_DEMO.ino#L1

In other words you need to know the label on the target volume. No label defaults to "/", AKA root part of the filesystem tree.

UHS30's filesystem automatically will mount upon initial detection, and there is a way to know when that event happens. See here: https://github.com/felis/UHS30/blob/master/libraries/UHS_FS/examples/USB_HOST_SHIELD/UHS_FS_NEW_DEMO/UHS_FS_NEW_DEMO.ino#L273

After that point, you are free to read/write as needed. Just do not forget to close all files, and sync the filesystem when all writes are done. You do not need to unmount it, that happens automatically as well once you remove or power down the target storage.

Thanks a lot.
My problem wit UHS30 had been that code execution does not go beyond
while(KINETIS_Usb.Init(1000) != 0);
the Aduino ADK just sits hear endlessly. Is there something i am doing wrong.
I use Arduino 1.6.8, Arduino AVR Board manager 1.6.11, Mega ADK Arduino, Windows 7.
Thanks a lot

from uhs30.

Sounds to me like a pin conflict, or I don't have something right for supporting the particular board.
I don't own one of these boards, so I can only make a guess that it is indeed a conflict.
If the SDcard library uses SPI, this indeed could be the case, especially if it does not use transactions.
Can you tell me which SDcard library you are using?

from uhs30.

For now, the problem is with the UHS30 example files. Even without the SD card shield, the code hangs when executing the line

while(KINETIS_Usb.Init(1000) != 0);

UHS20 example testusbHostFAT.into works on my board. I don't know why UHS30 examples will not work.

Could it be the cs_pin for the max3421 chip? On my board, max3421 seems to be on pin 10, the SD card shield is on pin 8

from uhs30.

Ok, that is fine, what are the MISO/MOSI/CLK line pin numbers?

from uhs30.

It uses the standard ICSP pins on Arduino mega

from uhs30.

Ok, did you connect 9 to pin 3 with a jumper wire?
https://github.com/felis/UHS30#avr-arduino

from uhs30.

I did. Nothing happened

from uhs30.

Do you know where the INT pin from the MAX3421E is routed?
Connect that to pin 3, and it should wake up and work.
UHS30 uses interrupts and does all the work in the background, which means no polling...

from uhs30.

I don't know where the INT pin of max3421 is, however, I will find out and do what you suggested.

I also noticed that the UHS20 with the examples from your github page didn't work either. I found one (probably modified) that ended up working. I will upload it to you in a few minutes. The difference might show something

from uhs30.

Try the following:
Connect pin 54 to pin 3
then... specify the SS/INT pins like so...
MAX3421E_HOST MAX3421E(53, 3); // SS on pin 53, IRQ on pin 3

from uhs30.

...if that works, I'll place this fix in the library

from uhs30.

I will check it out and give you a feedback if it works. Meanwhile, the link to the UHS2 that worked on my board is presented here:

https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_06_Microduino_USBHOST_MAX3421E

from uhs30.

@xxxajk please see how I have done it in UHS2.0: https://github.com/felis/USB_Host_Shield_2.0/blob/ff8bdb24c19f254aa0496d3933920f3ae92f85a0/avrpins.h#L31-L32, https://github.com/felis/USB_Host_Shield_2.0/blob/ff8bdb24c19f254aa0496d3933920f3ae92f85a0/avrpins.h#L514-L517, https://github.com/felis/USB_Host_Shield_2.0/blob/ff8bdb24c19f254aa0496d3933920f3ae92f85a0/UsbCore.h#L37, and https://github.com/felis/USB_Host_Shield_2.0/blob/ff8bdb24c19f254aa0496d3933920f3ae92f85a0/usbhost.h#L158-L162.

from uhs30.

@Lauszus difference--- UHS30 needs an actual real IRQ pin....

from uhs30.

Thanks so much. I will check it out. However in your previous post

I guess you meant,
"Connect pin 53 to pin 3" and not "Connect pin 54 to pin 3".
Pin 54 & Pin 55 are GND in Aduino Mega

from uhs30.

If this is a regular Arduino mega with a USB host shield, then the jump from 9 to 3 should work.
The ADK isn't the same thing and those pins are in a different location.

from uhs30.

I think I found out something on the Aduino Mega ADK for use as USB Host

1. The MAX3421E communicate with Arduino with the SPI bus. So it uses the following pins:
   Digital: 7 (RST), 50 (MISO), 51 (MOSI), 52 (SCK)

2. Digital pin 7 should not be used as input or output because is used in the communication with MAX3421E

3. There are three Connections to the MAX3421E through Non broken out on Headers:
   PJ3 (GP_MAX), Pin66 on ATMEGA 2560
   PJ6 (INT_MAX), Pin69,pin8 on ATMEGA 2560
   PH7 (SS). Pin27 on ATMEGA 2560 Pin53 on Arduino ADK Header

http://www.electroschematics.com/7965/arduino-mega-adk-pinout/

4. There seems to be an error in USB_HOST_SHIELD.h for the Aduino ADK.
   lines
   81 #elif defined(BOARD_MEGA_ADK)
   82 #define UHS_MAX3421E_SS_ 53
   83 #define UHS_MAX3421E_INT_ 54

54 in line 84 should be referenced to PJ6 (since it has no broken out header, I don't know how to properly label it). *I could be wrong about this Sir

Pin 54 on Aduino Mega and ADK is GND
http://download.arduino.org/products/MEGAADK/arduino-mega-adk-schematic.pdf

5. Is there any other library files that needs to be modified in UHS30 appart from USB_HOST_SHIELD.h to effect this changes.

Thanks

from uhs30.

Hi,
In USB_Host_Shield_2.0: avrpins.h
P54 and P55 (line 514-517) were properly defined. I am not sure of whether it was so done in UHS30

#ifdef BOARD_MEGA_ADK // These pins are not broken out on the Arduino ADK
#define P54 Pe6 // INT on Arduino ADK
#define P55 Pj2 // MAX_RESET on Arduino ADK
#endif

Sorry for my troubling.
Here is my Board
https://www.aliexpress.com/store/product/MEGA-ADK-2560-R3-Enhanced-version-Swith-for-I-O-5V-3-3V-USB-CH340G-USB/1950989_32672086405.html?spm=2114.12010608.0.0.2995e5c0nS6V2R

from uhs30.

You will need to locate where the INT_MAX pin is, and connect it to pin 3.
The MEGA ADK has different pin numbers than the regular MEGA.
What I see in your picture is basically a MEGA2560 with the MAX3421E on-board.

Do they provide a schematic?
Perhaps you need to compile for plain MEGA2560?

from uhs30.

FYI the official Arduino Mega ADK is totally different from this board too.

from uhs30.

Any chance on donating one to me so i can figure it out?

from uhs30.

1. They did not provide a schematic. I have wriien the sellers though, they promised to get back to me.
2. INT_MAX seems to be hardwired to MAX3421E chip...I am still trying to confirm that though.
3. I will attemt to comple of the plain MEGA2560 as suggested.
4. I could donate a board if you send me your shipping address in private. (You know my email address).
5. In the mean while, can you help me with solving this problem of moving data from SD card to USB Flashdrive with UHS20?(Since I already have a working code with the ADK)..

The working code is:
https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_06_Microduino_USBHOST_MAX3421E

Thanks

from uhs30.

Definitions seem to be identical, I'll see what I can find out as far as the actual tie points for these pins.

from uhs30.

#ifdef BOARD_MEGA_ADK // These pins are not broken out on the Arduino ADK
#define P54 Pe6 // INT on Arduino ADK
#define P55 Pj2 // MAX_RESET on Arduino ADK
#endif

Looks like you will have to find a good place to tap in on these two wires.

Are you capable of doing fine soldering?

from uhs30.

P54 I mean, not the reset one :-)

from uhs30.

Looks like this is actually a valid /INT pin!

from uhs30.

Thanks. I will check out the Board for the possibility of tapping PE6 and PJ2. I am not sure I can do fine soldering though but I am willing to givebit a try.

Is there no way round UHS20 for the working code code, while solution is being sought for the ADK board?

https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_06_Microduino_USBHOST_MAX3421E

Thanks

from uhs30.

Well, there are two options to get this to work without soldering.
1: make a new set of read/write/mode for the digital pins.
OR
2: fix the definitions for the ADK in the Arduino definitions....

I think the first one makes the most sense at this point, and is very easy to do.

from uhs30.

1. Which of the libraries need to be tweeked to Making a new set of read/write/mode for the digital pins in the library and How do you suggest it be implemented.
   (I wouldn't mind going by this as a first option before having a permanent and generic solution to the problem-at least to have a working project).
   The problem looks so simple, yet daunting.

2. I assume it is more difficult to get the UHS20 move data between SD card and USB FlashDrive.

from uhs30.

Easier to work around in UHS30, UHS2 is horrible for this.
Working on the patch for you to test, it seems to only be half broken :-)

from uhs30.

I just got the schematic to the Arduino Mega ADK board by Robotdyn. I will send it now through my mail.

from uhs30.

Please send to my personal email, available off of my own github page. Just click my Avatar :-)

from uhs30.

from uhs30.

Send to my personal email as an attachment please.

from uhs30.

Thanks in anticipation for the patch. A million cheers to you if it works.

Thanks

from uhs30.

On your board, which of the following resistors are populated (IF THESE ARE MARKED!)
R11
R12
R13
R16

from uhs30.

I hope you can confirm this from the schematic
MAX3421E. ATMEGA2560. ADUINO ADK
RST_3V3 PH4/PJ2. PIN7
SCK_3V3. PB1. PIN52
SS_3V3. PB0. PIN53
MOSI_3V3. PB2. PIN51
MISO_3V3. PB3. PIN50
GPC_3V3. PH5/PJ3. PIN10
INT_3V3. PH6/PE6. PIN9

If this is true, an easy work around should be possible

from uhs30.

Sorry. This is gabbled up. The formating was messed up. I will send it through my mail again

from uhs30.

I just resent it as an *.rtf attachment.

from uhs30.

All the resistors mentioned are marked

from uhs30.

Try now...

from uhs30.

What about the following changes

1. In USB_HOST_SHIELD.h
   81 #elif defined(BOARD_MEGA_ADK)
   82 #define UHS_MAX3421E_SS_ 53
   83 #define UHS_MAX3421E_INT_ 9 //modified from 54 to 9

2. In what other files can one rectify this?

from uhs30.

Leave it as 54

from uhs30.

Sorry, I checked a wrong Board.
None of the components were labelled.

from uhs30.

Not a problem. Does the new code work?

from uhs30.

1. I havent seen the New Code. Did you send it to my mail or you uploaded it to your github page?

2. I hope you have confirmed this from the schematic. They look normal and INT can be taken fro Pin9, I dont know why it is not working
   MAX3421E............... ATMEGA2560............... ADUINO ADK
   RST_3V3 __________PH4/PJ2.______________PIN7

I reverted back line 83 to #define UHS_MAX3421E_INT_ 54

from uhs30.

Do a pull from github :-)

from uhs30.

Ok.
I will feed you back as soon as I test it. Thanks

from uhs30.

no problem :-)

from uhs30.

The new code still get stuck when executing the line

while(KINETIS_Usb.Init(1000) != 0);

I have put the jumper
between pin9 and pin3
between pin53 and pin3
with no jumper

from uhs30.

Should be no jumpers needed with new code.

from uhs30.

Also compile with board as the MEGA ADK

from uhs30.

Even with no jumper.
It prints Start. on the serial monitor and then waits indefinitly

from uhs30.

Try this with the board_qc example.

from uhs30.

Yes. I did compile it as

1. Mega ADK
2. Mega 2560
3. Changed Board in case it is faulty
   Nothing seem to work

from uhs30.

Please try board_qc as Mega ADK, no jumpers, and it should print something out, after you pull this new patch.

from uhs30.

What do you mean by board_qc?
Did you upload a new patch?

from uhs30.

https://github.com/felis/UHS30/blob/master/libraries/UHS_host/USB_HOST_SHIELD/examples/board_qc/board_qc.ino
It is under the examples for USB Host Shield.
Yes I uploaded a new patch. :-)

from uhs30.

This is the Result from the Serial Display

from uhs30.

Please see if you have +5v on pin 12 on the MAX3421E.
I will send you a picture of where to test to your private email.

from uhs30.

Sorry, 3.3v

from uhs30.

There is 0.85V between Pin12 and GND

from uhs30.

Sorry my error. Pin12 on the MAX3421E chip you mean?

from uhs30.

Yes.

from uhs30.

Sent you the pin to check to your email.

from uhs30.

I am on it. The pins are so tiny I want to activate my usb microscope to see where i am probing

from uhs30.

No problem, I am probing here as well on the ATMega, using mine.

from uhs30.

Pushed a new patch, pull, try board_qc again.

from uhs30.

Just Did that. The same Result on Serial Port

Circuits At Home 2011

from uhs30.

Unsure what the exact issue is, the port/pins should be correct now.
I probed them on my regular Arduino Mega2560 at the actual MCU.

Try this short sketch, it will toggle the reset and int pins.

#define PULSE_DELAY 100 

void setup() {
        DDRJ |= 0x04; // output
        PORTJ |= 0x04; // HIGH
        DDRE &= 0x40; // outputput
        PORTE |= 0x40; // HIGH
        pinMode(LED_BUILTIN, OUTPUT);
        digitalWrite(LED_BUILTIN,HIGH);
}

void loop() {
        PORTJ |= 0x04; // HIGH
        PORTE |= 0x40; // HIGH
        digitalWrite(LED_BUILTIN,HIGH);
        delay(PULSE_DELAY);
        PORTJ &= ~0x04; // LOW
        PORTE &= ~0x40; // LOW
        digitalWrite(LED_BUILTIN,LOW);
        delay(PULSE_DELAY);
}

Do you have an oscilloscope or multimeter with the ability to sense frequency? If so, the RESET and INT pins should be pulsing in the above test.

from uhs30.

I do not have the Oscilloscope around, but I was able to do a work around by slowing down the oscillation (delay 2000) and viewing the Output with LED.

My observations:

1. Pin7 and Pin8 Toggles ON/OFF
2. The Oscillations on Pin7 and Pin8 are in Phase
3. I am not sure which one of them is INT and which is RST
4. Pin9 is permanently ON

Was this your intention?

from uhs30.

of course Pin13 goes in sync with Pin8 and Pin7. Same phase and Same Frequency

from uhs30.

All right, in that case, the creators of this board tied pin 7 an 8 to the "hidden" pins.
That's pretty interesting, and not really how the official ADK works, but should not pose a problem as long as you don't use pins 7 and 8.

This is actually progress :-)

Are you certain it is pins 7 and 8 and not 7 and 9?

from uhs30.

I am certain.
Pin 7 and Pin 8 Oscillates
Pin 9 is permanently ON

from uhs30.

Hi,
I noticed an important difference in the port assignment between the Standard ADK and the Robotdyn ADK
Except if the supplied schematic is wrong.

RobotDyn ADK______________________MAX3421E______________________Arduino ADK(Standard)
PH4/PJ2_____________________________RST_3V3_________________________PH4/PJ2
PB1 (Pin52)__________________________SCK_3V3________________________PB1_SCK (Pin 52)
PB0 (Pin 53)_________________________SS_3V3__________________________PB0_SS/PH7 Pin (53)
PB3 (Pin 50)_________________________PB3_MISO_______________________PB3_MISO (Pin 50)
PB2 (Pin 51)_________________________MISO_3V3_______________________PB2_MOSI (Pin 51)
PH5/PJ3_____________________________GPX_MAX________________________PJ3
PH6/PE6_____________________________INT_MAX_______________________PJ6/PE6
FROM:
http://download.arduino.org/products/MEGAADK/arduino-mega-adk-schematic.pdf
and the RobotDyn Supplied Schematic
The major problem seems to be that
PH6/PE6_____________________________INT_MAX_______________________PJ6/PE6
INT_MAX is connected in addition to PE6 differently:
Robotdyn allowed a connection to PH6 while the Standard Arduino ADK allowed connection to PJ6
the non critical difference is the connection
PB0 (Pin 53)_________________________SS_3V3__________________________PB0_SS/PH7 Pin (53)
where the standard connected SS_3V3 to PH7, whereas PH7 was unconnected in Robotdyns board.

What do you think?
It is even possible that bot schematics have been reviewed since published.

from uhs30.

From Robodyns Schematic,(if it is correct),
Pin_____PORT________MAX3421E
Pin 6= PH3
Pin 7= PH4/Pj2---->RST_3V3
Pin 8= PH5/PJ3--->GPX_3V3
Pin 9= PH6/PE6--->INT_3V3
Pin10= PB4
Pin13= PB7
Pin53=PB0--------->SS_3V3
Pin50=PB3--------->MISO_3V3
Pin52=PB1--------->SCK_3V3
Pin51=PB2--------->MOSI_3V3

Seems all the connections to the MAX3421E chip were made accessible

from uhs30.

I made a spreadsheet, and should be able to run some kind of test to determine what kind of "ADK", official, or quirky clone.

Part of the difference should actually not matter, however it is wired differently for /INT.

from uhs30.

Whao!
So much difference between the Official and Robotdyn ADK. I am sure except for their own library as in https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_06_Microduino_USBHOST_MAX3421E , No other library would work with the MAX3421E chip.

I guess this is the problem with Chinese clones: with almost no documentation. I am surprised you were able to get the Table above. The schematic supplied by the seller to me actually seems not the same that was implemented.

I guess I have learnt a lesson. "Never use a Chinese Clone for prototyping: to avoid endless Headaches and Time waste".

Thanks so much for spending so much time on this.

1. From your earlier Port Test Sketch,

#define PULSE_DELAY 100
void setup() {
DDRJ |= 0x04; // output
PORTJ |= 0x04; // HIGH
DDRE &= 0x40; // outputput
PORTE |= 0x40; // HIGH
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN,HIGH);
}
void loop() {
PORTJ |= 0x04; // HIGH
PORTE |= 0x40; // HIGH
digitalWrite(LED_BUILTIN,HIGH);
delay(PULSE_DELAY);
PORTJ &= ~0x04; // LOW
PORTE &= ~0x40; // LOW
digitalWrite(LED_BUILTIN,LOW);
delay(PULSE_DELAY);
}

I assumed you did intended to toggle PJ2(RST ) and PE6(INT), and by the Table, it should correspond to Pin7(PH4) and Pin9(PH6)
but
Pin7(PH4) and Pin8(PH5) Toggles ON/OFF while Pin9(PH6) is permanently ON.

This would mean that INT on Robotdyn ADK is actually PH5/PE6 and not PH6/PE6 as the table suggests.
2. How critical is the connection to PH6 which seems to be missing in Robotdyn ADK?
Thanks

from uhs30.

Yup, that's where even sometimes it is actually even better to build your own boards too.
Considering that the code was tweaked to use PE6, it should actually work.
One huge difference also is that on the official Arduino ADK, the alternate pins are not connected, and are optional connections.
This difference could possibly be part of the issue as well.
One possible solution would be to locate where on the board the junction is made, and disconnect the secondary connections.
Another possible problem with this board (judging by the schematics) is that there are no buffer chips to convert the signal levels from the MAX chip to the ATMega. While typically this shouldn't be an issue, it could actually be, since the waveform characteristics would be very different.
Another problem with doing it the way they did is that if the INT/MISO/GPX lines are set to PULL_UP, the backwash of +5v to the +3.3V signal may damage the MAX3421E.
Furthermore, MISO should be gated via the buffer IC so as when /SS is not low, that MISO is tristated, and not visible on the SPI BUS. Even if the MAX3421E DOES tristate alone, this is not enough, because anything ELSE connected to the SPI BUS is goping to be talking at +5V, and fry the MAX3421E that way too.

from uhs30.

My only consolation now is that their own library seems to work.

An easy solution will be to purchase the Standard Arduino ADK and get on with the project, but that will take approximately 3 weeks of waiting for the shipment. It is sometimes impossible to trust the schematics you get from China. They could have done 21 revisions after the publication for their own consumption.

It looks like they have buffer chips to convert the signal levels from the MAX chip to the ATMega

I have tried to compare what they did (they heavily modified your code) with your USB_Host_Shield_2.0
with a view of noting the important difference to no avail. ...my coding skill isn't that strong.

Can you please help with the easiest solution that you think while I try to get a Standard Arduino ADK? I will surely appreciate this.

You may need to reroute the int line to pin 3, plus some other stuff, possibly.
Quite busy with work currently.
As far as what board to compile for/what demos, use only the demos for the host shield, and select mega ADK.
Again, I do not actually have this board, so I can't really tell you why it doesn't work. If you can send me one, then I could probabbly get it running in a couple minutes, and tell you what to modify.

I did a checkup for Arduino Mega ADK from their site
https://store.arduino.cc/arduino-mega-adk-rev3
the board seem to be out of stock. Is there a local site near you where I can purchase it online?

I can pay for it once I know your shipping address.
Pls use my private mail to ensure confidentiality.

Thanks so much.

Click my avatar, you'll get my email address and I'll give details.
No, there is no local stores that carry any such items.

Let me know here if it also works for you, it should.
I shall be pushing the patch very soon.

from uhs30.

Hi,
Your patch works like a charm on both my ADk clone Robotdyn Arduino Mega ADK and the Official Arduino Mega ADK. I gues the patch can now be made public.
Thanks so much for the effort you have put.

Unfortunately, it doesnt support the SD card all the SD card libraries i know. I have tried SD.h, SdFat.h, SdFs.h and SduFat.h.

'Sorry to ask, What does UHS_KINETIS_FS_HOST Do? The two examples do not compile on the ADK. You might want to check them out.

I am happy the code works but will prefer both the SD and the USB card shields work together.

The Output of the UHS3 I paste Here Below:
Thanks so much.

Since the UHS30 and the SD card FAT system seem to share a lot in common, wouldn't it be nice if the UHS30 can also handle SD card functions?

from uhs30.

I guess the easiest solution by which to resolve the namespace conflicts is to modify an SD card library specifically for the UHS30.

from uhs30.

Closing, problems assumed resolved.

from uhs30.

Heads-up... SD card on SPI is now supported. You must have the SDcard detect pin connecting to a real interrupt pin or ARM MCU with built-in pin interrupts for it to work.
