@Xeon said in M5stickC:

i have not been able to compile anything for a entire year.
and it's not the computer... 2 different machines doing the same thing tells me it's your software
does not matter what board or libs i choose.
it wont compile anything for the m5stick.. and it often breaks everything else.

on top of this i am still waiting for a delivery for the replacement stickV
no one contacted me after wards.

lack of info on what are you trying to do really

@domi
Are you using the "4Relay module" or the "4Relay unit" or the "2Relay module" ?

If you still get an error, try to make a simple Uiflow programm scanning the i2c bus with the 4Relay connected:

You should get the number [38, 117] displayed as Label0, 38 is the decimal for 0x26.
If you get 37 you have another firmware than I have (I2C address 0x25).
If you only get [117] your 4Relay module is not connected to the M5Stack core. 117 (0x75) is the I2C address of the battery management chip.
