Test code attempting to drive a Ebay SSD1306 128X65 LCD from STM F303K8. The chip responds my I2C address scanner but the LCD never turns on or displays anything.
Dependencies: SSD1308_128x64_I2C mbed Adafruit_GFX
Fork of
Nucleo-F303K8-ADC-TEST

Update of sample using Adafruit library to drive a generic Ebay SSD1306 OLED display. On Nucleo-F303K8 it will display reading of first two ADC lines once every couple seconds. Should work with other CPU boards.
