I am trying to debug my code. I have a timer function which is called every minute but as soon as it triggers, my LCD goes BLANK (white). This is similar behaviour if u remove the reset pin from my 8 but LCD. So my question is , is the timer someone connected to some pin which could be causing this?? sorry cant share code its for a job.
If you code isn't doing it it shouldn't happen.
However, get an oscilloscope and check the actual pin level.
Sharing your timer code might also be a good idea.
