can someone please explain this MPLAB IDE v8.00 PIC C code to me?
It is a program using PIC 16F877 to get the data from an ECG, respiration rate, pressure and heart rate circuit and display the output in an LCD and further serial communication is done via zigbee to view it on a laptop.

 

Which part of the program,or if you are asking about the full program then I am sorry you need to learn about PIC and C try some tutorial or books.Have a google search....it may help

Good Luck and welcome to AAC
