PROBLEM IN THONNY'S BACK-END: Exception while handling 'Run' (ConnectionError: read failed: [Errno 6] Device not configured).
See Thonny's backend.log for more info.
You may need to press "Stop/Restart" or hard-reset your CircuitPython device and try again.
Process ended with exit code 1.
Unable to connect to /dev/cu.usbmodem0740D1EC05011: [Errno 2] could not open port /dev/cu.usbmodem0740D1EC05011: [Errno 2] No such file or directory: '/dev/cu.usbmodem0740D1EC05011'
Description
Board: adafruit-esp32-s3-tft-feather
SDCard: SPI (MI, MO, SCK, RX-CS), 3V3
Audio: MAX98357A (A0-BCLK, A1-LRC, A2-DIN, A3-GAIN), 3V3
Speaker: 4O 3W
Wav file: /sd/music/xzl2.wav, 16Bits, 22KHz, filesize is 15539848
When I run the code, the speaker plays sound.
But after a while, the board reboots and enters the boot mode.
The restart time is uncertain, sometimes after outputting 1 2, it restarts.
Sometimes, the output number exceeds 30 before restarting.
Additional information
- code to check whether the wav file can be read normally
