Feather M0 express pull ups.

Post by Confundo »

I have followed the wiring diagram tested with a little bit of code (adding mma8451 accelarometer) to a feather M0 express: and get

Traceback (most recent call last):
File "code.py", line 3, in <module>
RuntimeError: No pull up found on SDA or SCL; check your wiring


My wiring is fine 3V to vin, gnd to gnd, sda to sda, scl to scl.

test code:

import board
import adafruit_mma8451
i2c = board.I2C()
sensor = adafruit_mma8451.MMA8451(i2c)


If you know whats wrong and have an answer, imagine you need to explain it to a stupid 5 year old, so you get my level of expertise with this :)

thank you

Can you post a clear close up of the connections to both boards?
