Hi, I have a 2 x 16 parallel LCD. It is attached to a protoshield attached to a UNO. It works fine on "Hello world" but when I have it hooked up to a thermocouple, it gives the Int temp as -127 and states T/C Problem. Then it goes bonkers with all 32 characters rapidly changing with various symbols…
