Hi Gordon, Dan ... Encountering exact same symptoms here, STM32F4Discovery board, (A0,A1,C0,C1,C2,C3 wiring) ... including the 'ever so slight' dimming on running the code. A DS18B20 on A2 runs perfectly. Have double-checked wiring, tried 1.62 and 1.63 . Changed 'rs' from A0 to A3 in case it was a button conflict, but no joy. Just a single bar of blank chars ... Any ideas?
Cheers, Jon
