Hello there, I've recently gotten my self a Adafruit Prop-Maker FeatherWing and Adafruit Feather M4 Express and got it setup per the lightsaber guide. I got it working for a whole 3 days until suddenly I got an error stopping the project. Going online I was able to find out what the flashing Neopixel on the board meant. Hooked it to the computer using the Mu Editor and ran serial to find this error.
Code: Select all
Traceback (most recent call last):
File "code.py", line 60, in <module>
RuntimeError: No pull up found on SDA or SCL; check your wiring
The code is from
https://learn.adafruit.com/lightsaber-f ... g/software and line 60 is
Code: Select all
i2c = busio.I2C(board.SCL, board.SDA)
I re-applied my solder on both board headers to see if maybe something happened to break something when I was testing, however I've had no luck. I've tested the feather m4 with some other applications and it appears to be working fine but maybe the FeatherWing went bad? I was only testing it with a 144 neo pixels strip, speaker, and RGB switch that all came with the project. Please let me know if there is anything I can try doing on the FeatherWing as this is my first experience with them.
