Hi,
I decoded the NEC80 remote system and I have the C-code in codevision version.
I had a lot of help from code from YAMPP project by Jesper Hansen.
W*W.YAMPP.COM

So I have the code for decoding a Nec-80 remote ( like Kenwood's)
Now I like to make a transmitter also. I want to use an ATMEL AVR uC for this.
Anyone done this?
I have no idea on how exact the generated carrier wave has to be..does it has to be Sinus to be perfect, or can I use Block signal?
Anyone?
