QWERTY keyboard Driver
PostPosted: Wed Aug 05, 2009 2:08 pm     Reply with quote
Hi PIC programmers,

I need help going about writing a code for a 8x12 matrix QWERTY keyboard. I’ve implemented the keyboard driver that is found in this forum to work with a 8x12 matrix, but it doesn’t do exactly what I want, and I’m not good enough programmer to modify that code.
Basically what I need to emulate a IBM PC keyboard and output that information through I2C. So for each key that is pressed there should be a make code, then a break code when the key is released. I also need to be able to handle a three key press which I don’t even know that information would be transferred through I2c. There are other features that is need for this keyboard but I need to get this part first.

Thanks for looking , any help is appreciated.
