Thanks for your reply.

I just need to transmit about 6 different codes.

The codes are from a proprietary remote (to control a piece of medical equipment). Presently, I do have the codes learned in my Pronto learning remote.

I would like to store the codes in the PIC using the DATA statement and transmit any of the codes based on certain external conditions the PIC will detect.

These are my initial thoughts (please feel free to comment on them):

Figure out the carrier frequency
Figure out if the IR code is PWM or simple high & lows

(I think I can get the above from the Pronto editor, I am trying to find my notes on reading the IR data through the PC software ProntoEdit)

Store the data in the PIC eg (HEADER PULSE), 2H,3L ....

AND the output pulses with the original carrier frequency (either produced by an external oscillator, or possibly by the PIC itself (comments please))

The combined data and carrier would drive a transistor that would be connected to an IR LED.


Comments, ideas suggestions please.

Thanks
