hmmm... i don't know if it has to do with me not building the device right or me not knowing how to use the debugging software right, but something's not doing the trick. To my knowledge, i double checked everything in both parts, the LPT connector responds fine to win 98, the GSR amp doesn't seem to have any anomalies in the hardware. I think i might be getting the address of the ADS1110A0 wrong, it's 1001000, which in hex is 48. But it still doesn't change the reading when i enter that. Maybe i'll give it a shot on another computer and if not i have to get someone to help me out....
