DEFINE_ZEROCROSS_ISR

(

)

Zerocross interrupt, call when 220V cross zero.

This function turn off all triacs that have duty < 100% and arm the triac timers for phase control. This function is frequency adaptive so can work both at 50 or 60Hz.

Definition at line 65 of file phase.c.

void phase_setPower	(	TriacDev	dev,
		triac_power_t	power
	)

Set power of the triac channel dev (interrupt safe).

This function approsimate the sine wave to a triangular wave to compute RMS power.

Definition at line 129 of file phase.c.

static void phase_softint

(

void *

_dev

)

[static]

Soft int for each _dev triac.

The triacs are turned on at different time to achieve phase control.
