Timo Karppinen / Mbed OS McLab10_OLEDrgb_L432KC_OS60_tk2

The code is developed for the hardware NUCLEO-L432KC and Digilent Pmod OLEDrgb. The purpose is to make students learn the development process and test that the hardware works fine. For converting this to Mbed OS 6 Adafruit_GFX.h needed to add #include "Stream.h" in beginning of the Adafruit_GFX.h Adafruit_SSD1331.cpp wait_ms(200) replaced with ThisThread::sleep_for(200ms); for all the similar wait_ms lines.

Dependencies:   Adafruit-GFX-MbedOS6
