pyb.I2C.SLAVE can't discover.

I create a I2C slave via:

Code: Select all

i2c = pyb.I2C(1, pyb.I2C.SLAVE, addr = 0x43)
then connect PB6(scl), PB7(sda), GND to other board, but i2c scan result is empty on other board, and I try to connect it to RPi's I2C also.

What step I missing ?

Re: Can't switch usb_mode ?

Solved, the USB mode can't switch in REPL after boot, so it must be config in boot.py .

Re: Can't switch usb_mode ?
