While looking for a solution to display characters over video for an on screen display I came across the Maxim MAX7456. This is one easy to use chip for exactly this purpose. Using a SPI bus it is easily interfaced with a PIC microcontroller (I'm using a PIC18F2520 for testing).
I have just started playing with this chip and have discovered how easy and powerful it is to use. I have one project in mind for it that I am starting on now and will post again once it is further developed.
I am trying to test it with breadboard and I use PIC16F877A.
ReplyDeleteDo you have a sample code to display some text on the screen?
Do I need pin 11 of Max7456?
