bus = I2C(0, I2C.MASTER, baudrate=100000, pins=("P19", "P20"))
return:
b'U\x02'
print(ubinascii.hexlify(bus.readfrom_mem(119, 0xD0, 1)))
b'55'
print(ubinascii.hexlify(bus.readfrom_mem(119, 0xD0, 2)))
b'5502'
and chip revision:
>>> print(ubinascii.hexlify(bus.readfrom_mem(119,0xd1, 2)))
b'0206'
it looks ok 550206
