hi
I'm thinking about designing a portable ecg unit, but i'm affraid about 2 or 3 dummie's things (after reading i'm still confused btw)0:
1: Two lead or 3lead testprobe?? 2: If i can use 2 leads for test purposes, wher i must place it in my chest??? 3: why if i put leads on the two corners of my chest even, i only recover a 60 hz amplified and homogeneous signal at the output of the ad8237 ( i followed the schema of the datasheet btw, except that i put 3.3V !!)
Am i doing something bad putting the AI to work at 3.3 ? or there's some constipation against me each time i use more than 3 opamps in a board?
has any one got code for LPC3128 to help me start?
