Run with overclocked compile? #5

Open enjoychang opened 9 years ago

enjoychang commented 9 years ago

Looks like this firmware only works with maximum 72MHz Compilation. Any progress on updated code for overclocked compilations, like 96 or 120 MHz?

Thanks.

Ctn use i2c with too high speed - this may be a problem with higher clocks.

Unfortunately i don't work on this project for a very long time so i can't really answer this, however what @CopterFail seems reasonable, the prescalers will go a bit crazy with cpu overclock, so you will have to compensate for that.

OK. Thanks, that make sense. Also I found the pwm output for esc doesn’t work with overclock either.
