but you're very very close Alain.....

Except in my application I'm needing to generate an 8ch PPM pulse frame at 22.5mS rate from scratch.

To cut to the chase what I want to do is build a simple RC TX radio eliminator so I can test prototype 2.4Ghz transmitter modules in the field (range tests etc etc) without needing a second person to wiggle the sticks on the radio (it uses Futaba compatible TX modules). I did the obvious thing and looked for existing projects but they all seem to decode PPM frames not create them...

The app will change the PPM period for two channels (at least) slowly so the servos move at the RX end while I move away doing testing (sometimes Km's). The remaining channels will just be 1.5mS center position all the time.

Sorry for the apparently newbie programming questions, I've actually written some quite large complex code in the past (way way past) but I do it so infrequently now I have to go back to basics at the start of a new project like a beginner. I never seem to do a similar project twice which doesn't help.

I guess another way of asking my question is can I have a lot of code in the interrupt handler subroutine ? Or could that bugger up the interrupt code ?

Thanks,
Martin
