I have a pi zero that I am connecting to a Pimoroni drum hat, and I need it to communicate over I2C.
I followed the steps here but when I run
sudo i2cdetect -y 1
the grid is filled with dashes and there is no I2C device detected.
I used a multimeter to check the connection from the drum hat to the pi, and they are all fine so it isn’t anything mechanical. What else might be wrong and causing the pi to not find the hat over I2C?
Thanks for any help.
