I have a 2pcs GrovePI+ and I have the same result.
I tried to connect official oled screen and official I2C motor driver and it doesn’t work. I used basic example for each board.
Nothing display on the oled screen.
On the motor driver, nothing happened and red and green LED on each side stay on.
I2c 0x04 is detected but nothing connected…
My log file :
log.txt (3.1 KB)
I already tried to re install but it is exactly the same.
thanks in advance for your help
