Thanks Bitmaniac,

Don't let me worry you! The speed difference will probably have a bigger affect on your PWM sensing and pass through, than altitude conversion. But I think 8mhz is reasonable for this. Yours is the motor control for a glider, so even if it is a little glitchy, you are not going to notice much, since to get to altitude you will probably be at 50 to 100 percent throttle, or you will be at 0 looking for lift.

I was originally thinking of speed for the higher bit conversions, like 15 and 16 bit. But I think the speed of your conversion will be 2 us, where with 20 mhz, the conversion is 1.6 us. So just the 16 bit analog oversampling takes 100 ms with 20 mhz and 125 ms with your 8mhz internal. Not a big difference there! Of course the 15 and 14 bit samples are MUCH quicker.

So no, really, I think you will be fine.
