ecg signal
Hi All:

I am relatively new to 16 bits.

My task is to sample an analog ECG signal from an ECG amplifier (0-3v analog). I am able to display the positive values of ADC on LCD, but unable to ADC/sample the negative going signals. Can anybody point me to sample code for sampling negative going signals.

I am using explorer16 board with PIC24FJ128GA010.

Thanks.
Vinod

Re: ecg signal
