Good Job! I remember watching the first video some time back.

Remember to comment the lines in your program so you can easily read what each line is trying to accomplish in your program.

I keep my code in many forms. I keep the asm file and hex file for all my programs that are written in assembler. I save them to my hard drive, server, CD R/W and USB key. I also save a printed copy of my program and keep the previous two versions (if available) of the program as well.

Debugging can be quite tedious. Depending what the problem is you are trying to debug dictates how you will handle debugging, I will sometimes skip to a section of the code in my program or add break points to see how much code gets executed before it fails. Tracking registers and variables helps as well.
You can preload timers and modify variables etc. It still can be time consuming though. In a lot of cases I will add features to my projects IE. LED flashes three times to indicate program
running or a section of code has completed, some idea as power on self test of a computer, its all up to you as the developer.

Keep up the good work, I look forward to future videos.
