No serial port enumerated for a QT Py M0 SAMD21
Adafruit » Arduino
by
5d ago
I am using a QT Py M0 SAMD21. It was working fine, then I wanted to call pwm() instead of analogWrite(). pwm() exists in the Seeed XIAO software, but apparently not in the QT Py code. Thinking that the QT Py and the XAIO were interchangeable, I specified to the Arduino IDE that the QT Py was a XIAO SAMD21 and uploaded my sketch. Now, the QT Py does not show up in the list of serial ports (i.e. /dev/ttyACM*). Is there a way to unbrick the QT Py? I tried holding down the reset button while powering it on, but that had no effect ..read more

Feather RP2040 crashes when connecting via MIDI to Pro Tools
Adafruit » Arduino
by

Hello there! I´m new here and not very experienced in programming, so please excuse me for any mistakes. My problem is with an Adafruit Feather RP2040 board, but maybe someone one here has some good insights, since there is also an Arduino board based on the RP2040. I chose the Adafruit one because of the Native USB with USB C connector basically. So here is the problem: i want to make the board control the Audio Software "Pro Tools". But when the software sets up the connection to the board, the board crashes. I know the board freezes beacause i can no longer upload new sketches unless i ..read more

ICM20948 Mag stopped working
Adafruit » Arduino
by
5d ago
I'm looking for help with a ICM20948 I've been using to try and use with an Arduino and an SD card module. After trying many different combinations of Arduino (R3 and Pro Mini) with the ICM20948 connected via QWIIC (I2C) connector or using regular SPI connections, and the SD Card module connected via SPI using a different CS pin, I haven't been able to get the sketch to initialize. The SD card module will work by itself and the ICM20948 "was" working by itself until recently. However, regardless of which unit I initialized first or what buffer settings or delays I put in the setup, whenever I ..read more

Compiler error when using TC_WAVE_WAVEGEN_MFRQ or TC_WAVE_WAVEGEN_NFRQ in zeroTimers
Adafruit » Arduino
by
6d ago
I have a rather odd issue compiling zeroTimers. I want to use a timer to generate a variable frequency with a 50/50 duty cycle. When I select TC_WAVE_WAVEGEN_MFRQ or TC_WAVE_WAVEGEN_NFRQ in the configure call, I get the below compiler error. I don't understand why the the difference. Ultimately it expands to 0, 1,2 or 3. It might be somehow related to the enum tc_wave_generation defined in zeroTimers.h though. The PWM waveform TC_WAVE_WAVEGEN_NPWM or TC_WAVE_WAVEGEN_MPWM macros work fine. Thanks for any insight.

Class or Documentation missing for NeoKey 1x2

Hi! I've just bought several NeoKey 1x2 feather wings, and while there is class Adafruit_NeoKey_1x4, there isn't a version for the NeoKey 2. I tried to adapt Adafruit_NeoKey_1x4 into a 2 key version, but I'm not sure what the button mask should be. Is someone from Adafruit able to assist, or supply a Adafruit_NeoKey_1x2 class?

Feather RP2040 resets when calling SPI.begin
Adafruit » Arduino
by
1w ago
I am modifying the Uncanny Eyes project and I'm trying to get each display running on separate SPI buses on the Feather RP2040. When I run the sketch the RP2040 keeps disconnecting and reconnecting. I have the debug level set to SPI and the debug port set to serial and it looks like it's crashing when SPI.begin is called, but I can't figure out much beyond that. I'm using the Earle Philhower RP2040 core and the SPItoMyselfAsync example works just fine with the pins I have defined, so I don't think the issue is anything physical with the board. Below is my setup code and the output from the ser ..read more

Power Nano via USB C with power-only cable?

Can I use a cable like this connected to a 3.7 or 4.5 battery pack to power a Nano?   https://www.amazon.com/gp/product/B0BFH ... =UTF8&th=1 It seems from the USB C PD spec that there has to be some sort of negotiation board to communicate the power requirements, but I'm hoping for a super simple connection here :) Thanks for making time to read this and respond. I appreciate all the knowledge sharing that goes on in the community! /Bill ..read more
