Hi i want to make this simple usb st4 interface circuit but i dont understand if it is necesary to program the pic microcontroller or not since i dont see any source code and any way of doing it. is it necesary a independent board to program the microchip and then put it into the functional circuit or it is not necesary any programming it simply works when you put the chip in the circuit without any more coplexity? is it easy to build? thanks.
