im working with an ecg circuit .i now have the ecg circuit , the problem is, i find difficulties in displaying it in a pc, otherwise in a LCD.
anyone who can help me?is there any software that i can use to easily display the waveform of an eacg circuit. i plan to use pic16f877a for the analog to digital conversion. thanks a lot. your response will be a great help for me.

 

The PIC16F877A is an obsolete chip, and will be more expensive. You should use its replacement, the PIC16F887.

 

Actually, you may want to consider an external ADC chip.

These offer more clarity and "truer" representation to the analog signal.

The result from the ADC chip can be easily fed into the microController.
