Suppport for Raspberry Pi Pico #2

Closed rodrigocmn closed 3 years ago

rodrigocmn commented 3 years ago

The new Raspberry Pi Pico's MicroPython does not support start, write and stop operations for IC2. These operations are used in the write_data function.

The solution I've found was to identify the board via uos.uname() and use IC2.writeto() operation. This solution is included in my forked version, so I will create a pull request in case you want to merge the code.

BTW, I've also included a fix for chinese OLEDs offset problem in this pull request.

I upgraded the driver from MicroPython 1.9 to 1.14, and replaced the i2c.start() i2c.write() i2c.stop() with i2c.writevto() which works on the ESP32 and RPI Pico.
