MC9S08RG60 Timed Keyboard Input

Vickyg — Tue, 14 Aug 2007 02:57:49 GMT

Well I'm back.

I can't seem to get my keyboard interupt.

I'm trying to set a timer and tell if a certain key is pushed a second time.

Can someone show me some code of a simple timed keyboard interupt timer sequence with comments.

TIA

Posting here, seems to be magic. As soon as I posted, I found what's prohibiting the keyboard interrupt.

Can anybody give me an idea of what PTCD does? This setting was different and changing it enabled keyboard input, but I really can't find help on what this is, or what it does.

Hi Vicky,

PTCD would normally be the data register for Port C. The place where you write to or read from to get/set port c's i/o.
