My code for TV remote and MIBAM for RGB control
Hi all, I made a RGB LED lamp with super bright RGB LEDs from sparkfun and control the color from my TV remote. I use 16F628s X2 because I couldnt get pulsein to work with MIBAM (inturupt timming issue) Here is the code if it will help anyone. Its not real clean but it works well
