Ok, I have a couple of multiplexers hooked up and working now. Basically, this will be an 8 channel Data Collector. I have it prototyped up to cycle thru the 8 channels and I also have one channel tied to the GPS Thingy so that when that channel goes high, it triggers the GPS to dump its latest reading. Now I have to work on the rest of the data collector, i.e. the eeprom, the rtc and making it cycle every 30 seconds, exactly. Its a start, and I am glad I have until June to make it work... hehe
When I get the Collector working, I will probably get with DaddyB and get that GPS from him and see if I can interface with it.
Also, I think it is kinda cool that I can control the 8 Channels (sending the Ready Signal AND receiving the RS232 per chanel) with just 5 pins on the PIC. Muxxing is GREAT!!!
