I ran into a problem where the struct.unpack() was failing on the BeagleBone, (due to how I changed the example to flush the serial buffer, and take measurements at a different interval) and the problem seemed to be that the bytearray object was too long for the format ( ">HH..."). That could be a MicroPython vs Python 2.7 issue, I'm not sure. In any case I ended up with a revised PMS5003 packet reading/parsing function to contribute:

def read_valid_packet_from(ser):
    buffer = bytearray()
    valid_packet = False

    while not valid_packet:
        n = min(32, 32- len(buffer))
        data = ser.read(n)
        data = bytearray(data)
        print("read: ", data)          # this is a bytearray type 
        buffer += data

        # look for packet start
        while buffer:
            if buffer[0] == 0x42:
                if len(buffer) >= 2:
                    if buffer[1] == 0x4d:
                        # found valid packet start
                        break
                    else:
                        buffer = buffer[1:] # re-start parsing on next byte
                        continue
                else:
                    break # might be valid packet start, not enough data
            else:
                buffer = buffer[1:] # re-start parsing on next byte
                continue

        #print("current buffer_len", len(buffer))
        #print("current buffer: ", buffer)

        if len(buffer) < 32:
            print("buffer_len", len(buffer))
            print("buffer: ", buffer)
            continue


        frame_len = struct.unpack(">H", bytes(buffer[2:4]))[0]
        print("frame length", frame_len)
        if frame_len != 28:
            # packet is invalid, yet had valid start pattern
            buffer = buffer[2:] # restart parsing after intitial start pattern
            continue

        checksum = struct.unpack(">H", bytes(buffer[30:]))[0]

        check = sum(buffer[0:30])
        if check != checksum:
            print("checksum didn't match", check, checksum)
            buffer = bytearray() # drop whole packet
            continue
        else:
            print("checksum passed")
            valid_packet = True

    return buffer

Awesome work!
Looking forward to it working with the M4_eyes!

I am noticing some audio clicking with the lower pitch changes. Is this similar to the cross-fading issues with the old voice changer on the atmega processors?

Hello.
I'm not so expert but I did some sketches for ESP8266 using SD.h library.
I would adapt the SDlistFiles.ino and similar SDWebBrowse sketches found here but in both cases I have the following error compiling with ARDUINO IDE:
error: 'File' does not name a type
File root;
^
Can anyone help me ? I simply changed the CS pin to num. 15.
Thanks:
here the adapted sketch:

/* SDlistFiles

*/
#include <SPI.h>
#include <SD.h>

File root;

void setup() {
// Open serial communications and wait for port to open:
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}

pinMode(15, OUTPUT); // set the SS pin as an output (necessary!)
digitalWrite(15, HIGH); // but turn off the W5100 chip

Serial.print("Initializing SD card...");

if (!SD.begin(15)) {
Serial.println("initialization failed!");
return;
}
Serial.println("initialization done.");

root = SD.open("/");

printDirectory(root, 0);

Serial.println("done!");
}

void loop() {
// nothing happens after setup finishes.
}

void printDirectory(File dir, int numTabs) {
while (true) {

File entry =  dir.openNextFile();
if (! entry) {
  // no more files
  break;
}
for (uint8_t i = 0; i < numTabs; i++) {
  Serial.print('\t');
}
Serial.print(entry.name());
if (entry.isDirectory()) {
  Serial.println("/");
  printDirectory(entry, numTabs + 1);
} else {
  // files have sizes, directories do not
  Serial.print("\t\t");
  Serial.println(entry.size(), DEC);
}
entry.close();

}
}

I'm trying this sketch with several Teensys: LC, 4.0, 3.5, and found it couldn't even forward the message the ESP32 prints out after resetting to boot mode without dropping characters. Attempting programming with ESPTool.py would fail as it couldn't even get past trying to connect.

If I comment out the pixel* calls in loop(), it works without dropping characters, and programming flash (at least on 3.5 and LC, Teensy 4.0 still has an issue, but it seems unrelated)

@dastels Pressing the snooze button while in clock is in"snoozing mode" causes the code to crash. Also happens when going into the settings page while the clock is snoozing.

This fails for CP5.0-alpha. It works for CP 4.1.0

PyPortal_ArduinoSelfTest/PyPortal_ArduinoSelfTest.ino includes "Adafruit_QSPI_Flash.h", which is not available in the Arduino IDE library manager. https://learn.adafruit.com/adafruit-pyportal/arduino-libraries shows installing library Adafruit QSPI. Online searching found https://github.com/adafruit/Adafruit_QSPI which says it is deprecated and no longer needed.

Commenting out the include, definition and block that references flash got it to run. Initial exploration with manual installation of the deprecated QSPI library, SdFat, or `SdFat - Adafruit Fork' failed various ways too.

PyPortal_ArduinoSelfTest.ino needs some attention, as well as «at least» the web pages https://learn.adafruit.com/adafruit-pyportal/arduino-libraries and https://learn.adafruit.com/adafruit-pyportal/arduino-test that reference the selftest program and needed libraries.

# Generate one period of sine wav.

sine_wave = array.array("H", [0] * length)
for i in range(length):
    sine_wave[i] = int(math.sin(math.pi * 2 * i / 18) * (2 ** 15) + 2 ** 15)

This only works for frequency near 440. The 18 should be length to be more general.

It seems the library MiniMQTT has changed. The code in PyPortal_MQTT_Control uses

# Set up a MiniMQTT Client client = MQTT(socket, broker = secrets['broker'], port = 1883, username = secrets['user'], password = secrets['pass'], network_manager = wifi)
But the latest MiniMQTT library from adafruit-circuitpython-bundle-py-20200516.zip
defines a signature of:
def __init__( self, broker, port=None, username=None, password=None, client_id=None, is_ssl=True, log=False, keep_alive=60, ):

Notice that "socket" and "network_manager" are no longer part of the constructor.

Error:
Traceback (most recent call last): File "code.py", line 205, in <module> TypeError: function got multiple values for argument 'broker'
The code seems to be out of date w.r.t to the latest version of minimqtt

The pdf overview guide for the Adafruit MONSTER M4SK dated 2019-10-21, as well as the corresponding website lists the following libraries as being required to build M4_Eyes:
Adafruit_GFX, Adafruit_ST7789, Adafruit_ZeroDMA
Adafruit_ZeroPDM, Adafruit_ImageReader, Adafruit_SPIFlash
Adafruit_TinyUSB, SdFat - Adafruit fork (not the standard SdFat fork)
ArduinoJson (not Arduino_JSON)

The above list is not sufficient. The following libraries are also required in order to build:
Adafruit_AM2320_sensor_library
Adafruit_Arcada_Library
Adafruit_TouchScreen
Adafruit_Unified_Sensor
Adafruit_ImageReader_Library
Adafruit_LIS3DH
Adafruit_NeoPixel
Adafruit_ZeroTimer_Library
Adafruit_seesaw_Library

In addition, it was necessary for me to pull the latest Adafruit_ZeroPDM library from GitHub, as the version obtained through the Arduino Library Manager was missing some recent updates.

It would be nice to have the documentation updated to save people time in the future.

Adafruit is unclear with exactly how to perform this project. I'm trying to compile this for my Adafruit Feather M0 Express Hallowing but I'm finding a lot of errors and being a novice I'm not sure what's wrong, me or the code. Following this guide (https://learn.adafruit.com/hallowing-all-seeing-skull/code-in-arduino) to here.

I did load the libraries and boards instructed but the only thing that wasn't clear was the Programmer. I've tried AVRISP MK II with the following results on Arduino 1.8.8 -

`Arduino: 1.8.8 (Windows 10), Board: "Adafruit Feather M0 Express"

Perhaps I missed a step, but this Learning System guide doesn't mention the need for the Adafruit_ZeroDMA library. Could be confusing if you're not familiar with Arduino compilation errors.

Maybe I'm doing something wrong but I formatted the drive as FAT32 and copied and pasted that code onto the board and it outputs that error. I tried using boot.py to allow it to write to its storage but no luck.

Edit:
SD Card: Samsung EVO 32Gb

Edit 2:
Using the fixed (but also raw) adafruit_sdcard.py from SD Cards producing OSError 19 #245 in the circuitpython git repo solved the issue. Thus the new issue is that the fix has not been added to the Grand Central.

In the new Digital Pot Stemma QT board, the pinout section refers to "Vb" when the silkscreen names it "V+" (like the datasheet. While Vb (bias voltage) makes sense, it's not what's on the board :-)

Hi all,

I was working from an example from the Learning System and found an error in the sample code. Turns out I see it once in the forums as well (but I don't know how to report that). To be honest, I don't remember copying in this code (but I must have, unless some Trinkets shipped with code that includes this error)

Hi! I think we need help from an adult here. I believe I've established that something in the cache is wrong, and this is breaking current PR builds. I created #1098 because of the failure we saw on #1084. With no change relative to master branch, the build fails. With an attempt to address the first error-ish text I saw in the build, nothing changes. When disabling the travis cache, the build succeeded.

I believe I could use my credentials on travis-ci to clear the cache but I don't want to do this willy-nilly.

I've noticed that the brightness setting doesn't work on the neopixel library on Crickit Feather. It does work on the circuitplayground.

The code for the FeatherWing Quote Display has a bug that shows up when using a Huzzah32. If the quote happens to more than 261 characters, you get a board fault. The test string on line 195 is about 40 characters too short to demonstrate the issue. The current set of quotes happens to have two that are longer than that test string.

But, first I had to find this bug. Line 15 received_code = decoder.decode_bits(pulses, debug=False) throws an error. Problem is decode_bits(pulses) doesnt like the debug argument.
Could be this is some expert level code magic I dont understand but it works when I delete debug=false... so thats my issue.

For reference, the adafruit_irremote library doesnt have a debug argument either.

Hello Im trying using the Circuit Playground Express with the cpx-expressive-midi-controller v1.2 code and when using alligator clips attached to objects, sometimes the notes are being played before my hand actually touches the object.

I've tried changing
keydown = [False] * 10
to
keydown = [False] * 5
and 20, 15, 1, etc. but nothing really has an effect.

I'm not sure if I'm doing something wrong or if this is not possible with the code?

Thanks in advance for any help.

Greetings all!

CircuitPlaygroundExpress_AudioSine.py seems to run only once regardless of the value of "loop".

This is on the Circuit Playground Bluefruit from ADABOX 14.

The loop=True doesn't appear to have any effect.

With loop=True, The sample plays once and then the program halts.

Changing it to loop=False resulted in the same behavior. The sample played once and the program halted.

Removing loop=Value entirely resulted in the same behavior. The sample played once and the program halted.

Text on the top line of the Pi Hole Ad blocker's stats.py showing the hostname writes to the second line.

I could be totally wrong, but should this be labeled 10.0um / 0.1L air and not 50 um / 0.1L air?

"Particulate matter per 0.1L air, categorized into 0.3um, 0.5um, 1.0um, 2.5um, 5.0um and 10um size bins"

I just tried M4_eyes on Monster mask from the updated Learning Guide and "voice" seems to be broken. If I enable it, I just get blank screens, nothing.. Without voice, everything is working fine. Is this a known issue?
I tried this example: https://learn.adafruit.com/adafruit-monster-m4sk-eyes/voice-changer-2#example-config-dot-eye-file-14-8
as well as just adding voice : true to other working "eyes"
In both cases, it just seems to hang during the start-up

The PyPortal_Openweather and pyportal_weather_station guides use TileGrid and have the "old" position kwarg. This was updated in displayio to take x,y kwargs instead.

Should they be fixed with try/except on TypeError to for "backward compatibility" of just updated for the latest version of displayio?

I just downloaded and used the build uploaded on 28Jan20, and while it's improved the idle audio playback dramatically, there's still a glitch in the idle audio every once in a while. It ranges from a quick pop to an oscillating sort of white noise. Not sure what the root of this is. Other people have also reported it. Not sure if this is a software playback issue or electrical problem, but it's only in the idle sound as far as I can tell. There was a comment about audio file length potentially being an issue.

Even when examples are changed and when CircuitPython changes.

The "reopen button" is not available. Regarding #1091, which is about Feather_ePaper_Quotes, found in https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/Feather_ePaper_Quotes and as described in https://learn.adafruit.com/epaper-display-featherwing-quote-display. The "fix" that was merged previously for this changed one fixed-length buffer for a slightly larger one. Instead of fixing the problem, it just postpones it until the new buffer size overflows.

I suggest you also change the strcpy() statement a few lines after the declaration on line 93

static char buff[1024];
. . .
strcpy(buff,str);

to this:

static char buff[512];
. . .
if (strlen(str) >= sizeof(buff)-1) { // protect against buffer overflow
strncpy(buff, str, sizeof(buff)-2);
buff[sizeof(buff)-1] = '\0';
} else {
strcpy(buff,str);
}

That will future proof the code.

Because of the small memory on the microcontroller, I also drop the size of buff back down a bit so you don't have such a large buffer floating around that is empty most of the time.

I'll put together a PR with this fix.

What must be changed in the sketch to use the GSM SIM800L Breakout module, like this: https://www.ebay.com/itm/SIM800L-V2-0-5V-GPRS-GSM-TTL-Port-LGA-Chip-Quadband-L-Shape-Antenna-for-Arduino/332800310271?var=541920377421
and TFT Display ILI9341 SPI Breakout?
Thanks

halt() is used a couple of places to indicate errors, but it doesn't actually exist.

When I try to compile and upload the PyPortal Arduino Self Test I get the following error:

Adafruit_QSPI_GD25Q.h: No such file or directory

I can't find this file on GitHub, and it no longer seems to be part of the QSPI library.

Hi,

I had a bit of a rough start trying to get going on a Hallowing M4, wanted to start with something really simple, so I went through the "Hallowing" directories in the repo. Hallowing/graphicstest compiled, but did not show anything at all, not even serial printouts which left me wondering... Went on trying the other examples, most of them did not even compile.

Only then I got a hint on IRC that they are probably not meant to work on the M4 at all and this indeed seems to be the case, and I was able to build and run M4_Eyes which proved the above point.

I don't know if I missed that, but would be cool to have a more prominent warning somewhere that "Hallowing" examples won't work on the "Hallowing M4".

In CircuitPython_PWM_Piezo.py, line 14, it gives the duty_cycle of 65536, when the correct range is 0-65535.

Hello,
I have an Adafruit Circuit Playground Express and a Crickit, and I would like to run Circuit Python to use the HAL 9000 code. I have tried loading the Circuit Python special Circuit Playground Express + Crickit build from here https://circuitpython.org/board/circuitplayground_express_crickit/, which is currently 5.1.0. When I put the HAL code on my adafruit, I get the error that the adafruit_crickit library cannot be found. I feel like I am missing some simple thing to get this working. I was under the impression that if I run that build, my code can just load those libraries. My code is at the root of the CIRCUITPY flash. Did the library name change? Have you tested HAL on 5.1.0? Does that build have any other dependencies? Any help would be greatly appreciated.

@dastels Hiya, I'm testing this out. Running PyPaint on PyGamer using circuit python 4.0.2 with latest libraries from bundle.
