Creating my own TV Tuner IR remote with a PIC16F684

While I was home this winter, I saw that the remote for our TV tuner was damaged physically, causing the buttons to not function responsively. Some of them just didn’t work. I saw this as an opportunity for a fun couple days’ project to build a new remote controller for the tuner. The TV tuner was manufactured by a brand name RealView and, as expected, I couldn’t find much detail about it. Thus, I had to reverse engineer the remote. From my previous experience in working with IR remotes, I had a hunch that the IR was most likely modulated at ~38kHz or ~56kHz.”
