Hey guys,
I have a project in which I need to interface LCD with pic16f877a
When I use 4MHz crystal it displays and everything works fine
But when I use any other crystal 8MHz or 20Mhz
It only displays black rectangles, I really need to switch it to 20Mhz and keep the LCD working
Don't know what the problem is.
