My first post! Wewhew!!! Well Currently I am waiting for my soldering iron to warm up and so I thought I would get one of these blog sites. I am working on my MCU (microcontroller) programmer. I am using an 8051 based MCU that has embedded flash so that you can reprogram it on your end system board which is ISP (In System Programming). The specific part I am using right now is the 89c51rd2 from phillips. I have to get back to soldering.
