Hello @alpaka

unfortunately GPIO36 (one of the GPIOs used for Port B) is an input only GPIO. See here - section M5GO Base Pins and here - GPI: GPIO34-39 can only be set as input mode and do not have software-enabled pullup or pulldown functions.

I2C however requires one GPIO as output (SCL) and one GPIO which can be an out- or input (SDA). Therefore Port B cannot be used for I2C.

Thanks

@felmue there is also a king running issue with the ENV III unit

Hello @Amedee

on M5CoreS3 the 5 V on the Groove ports needs to be enabled explicitly. See section Power Management here.

Try calling below function in setup():

M5.Axp.powerModeSet(POWER_MODE_USB_IN_BUS_OUT);

Thanks
Felix

StickC (Not Plus) reports RoverC not connected.

Look in the Discussion about the ENV III and the Core S3

Hello @jaysom

please find a simple touch application drawing random colored circles here.

Thanks

Doesn’t look like there will be anytime soon.

I’ve reported it to M5STACK and they are looking into it

Nope still hanging
