RPi.GPIO python module for Pine A64/A64+

[psychedup]

Since I'm running Armbian, I'm using /dev/i2c-1 instead of /dev/twi1.
But here is some code I'm using to make some LEDs flashing on an MCP23017 :

Code:

#!/usr/bin/env python

import sys, time
from RPi import I2C as i2c

i2c.init("/dev/i2c-1")
i2c.open(0x20)
i2c.write([0x00, 0x00])
i2c.write([0x01, 0x00])
while True:
    i2c.write([0x12, 0x0F])
    i2c.write([0x13, 0x0F])
    time.sleep(0.15)
    i2c.write([0x12, 0xF0])
    i2c.write([0x13, 0xF0])
    time.sleep(0.15)

Thanks, I found the problem thanks to your example. I was trying to open "/dev/twi1" which didn't exist. It's /dev/i2c-1. For some reason when I run i2cdetect or i2cdump they want me to use twi1 as an alias to /dev/i2c-1 so I got them mixed up.

Now it is reading from the device. I just have to figure out what to do with the results

Thanks for your help.
