Function Documentation

§ CheckAnalogLine()

struct Mc_AnalogLine CheckAnalogLine	(	int	pin,
		uint16_t	num
	)

Test analogic line.

This function samples an analogic input to read lower, higher , mean and, rms values. inoltre - althought you can see the number of samples and the kalmann filtered value. This last value is useful to test lines wich signal is stable (or may be it).

Parameters

pin	is the analogic pin you want to test
num	is the number of "grid waves" you want to sample (default 450 if you don't specify values).

Returns: this funtion return a Mc_AnalogLine structure.

§ kalman_update()

void kalman_update	(	kalman_state *	state,
		double	measurement
	)

This function updates a Kalman filter.

Parameters

state	is the actual kalman filter pointer
measurement	is the new value you want to filter

Returns: this funtion DON'T retrun nothing because the original filter is modificated
