So for all of you asking, "why would anyone do this?" the answer is two-fold. Believe me, the irony of programming a PIC chip with an ATMega is not lost on me. This is how the idea for this project came to life. Glancing at some of my extra devices lying around, I noticed an unused Arduino. Rather than spend the $40 to buy a PIC programmer (thus, accumulating even more junk I don't need), I decided to think about how I could make this happen. Instead, it only supports Microchip's In-Circuit Serial Programming (ICSP) protocol via direct serial communication. Lo and behold, I didn't read the docs properly this chipset doesn't have a USB to serial interface. When I bought these chips I figured I could easily rig a board up to the chip via USB. ![]() The problem I now had was that I didn't have a PIC programmer. However, this time the bet paid off! Only about a year or two too late but that's beside the point. Yes, I know, this is a horrible way to actually build something and a great way to accumulate junk. I figured someday I could use these in something. A while back I bought a couple of PIC16F57 ( DIP) chips because they were dirt cheap. ![]()
