Function Documentation

getIcuParams()

bool getIcuParams	(	brain_pin_e	hwPin,
		iomode_t *	af_ptr,
		ICUDriver **	icu_ptr,
		icuchannel_t *	channel_ptr,
		uint32_t *	clock_ptr
	)

ChibiOS limitation is that only channels #1 and #2 could be used for input capture Could this be unified with getConfigForPin() method?
