I am an analogue guy but i need to add a digital bit to my work, but i don't know how . I need c code to control the gain of my instrumentation amplifier through a programmable digital potentiometer with 128 gain steps using a PIC 16F877A. i need to send the output of the amplified signal of the instrumentation amplifier to a PC. I need help, cause all my colleagues are analogue inclined too.
