Hi,

I had a problem with my LCD where about only half the letters were correct and the rest was random letters. Turns out I didn't have the capacitor in the right spot and it was fine once I put it in the right spot, but I was curious as to how the capacitor fixes this issue?

What capacitor did you have?

Where was the incorrect spot?

Where is the correct spot that made a difference?

Hi mcgroover,

My bet is (and what I think Ralph is getting at) is that you had the capacitor across one or more of the wires going to the LCD. This was causing some of the timings to be off when the MCU was talking to the LCD.

Hi guys!

This was during the instalload project of the nerdkits guide. Unfortuntely, I have now forgotten where it was. I thought it was connected to an empty row (and hence not connected at all), but it could well have been connected to the wires going to the LCD. Anyway, I was just curious, so thanks for the help!
