8 channels AC dimmer

Example :

main.c

/*********************************************************************
 *               dimmer example for Versa2
 *  Connect dimmer board to Versa's VNH2 port.
 *********************************************************************/
#define BOARD Versa2
#include <fruit.h>
#include <dimmer.h>
t_delay mainDelay;
 
//----------- Setup ----------------
void setup(void) {  
    fruitInit();            
    dimmerInit();        // init dimmer module
    delayStart(mainDelay, 20000);   // init the mainDelay to 20 ms
}
 
// ---------- Main loop ------------
void loop() {
    fraiseService();// listen to Fraise events
    dimmerService();    // dimmer management routine
    if(delayFinished(mainDelay)) // when mainDelay triggers :
    {
        delayStart(mainDelay, 20000);   // re-init mainDelay
        //dimmerPrintDebug();       // 
    }
}
 
// ---------- Interrupts ------------
void highInterrupts()
{
    dimmerHighInterrupt();
}
void lowInterrupts()
{
    dimmerLowInterrupt();
}
 
// ---------- Receiving ------------
void fraiseReceive() // receive raw bytes
{
    unsigned char c=fraiseGetChar();
    if(c==40) dimmerReceive(); // if first byte is 40, then call dimmer receive function.
}

Settings to put in config.h
You must define the pin used to trig the interrupt (sensing the AC zero-crossing): #define DIMMER_INTPIN K9 (replace K9 by the pin used by your dimmer) The following parameters can be overloaded:
#define	DIMMER_INTEDGE
	Edge of the interrupt (0:falling edge ; 1:rising edge) ; default: 1(rising edge).
#define	DIMMER_TIMER
	Timer to be used by the dimmer module (only 1, 3 or 5 ; default: 5).
#define	DIMMER_K0
	output pin for channel 0.
#define	DIMMER_K1
	output pin for channel 1.
#define	DIMMER_K2
	output pin for channel 2.
#define	DIMMER_K3
	output pin for channel 3.
#define	DIMMER_K4
	output pin for channel 4.
#define	DIMMER_K5
	output pin for channel 5.
#define	DIMMER_K6
	output pin for channel 6.
#define	DIMMER_K7
	output pin for channel 7.
#define	DIMMER_TMIN
#define	DIMMER_INTPRI

Initialization
void	dimmerInit (void)
	Init the module in setup()

Main loop functions
void	dimmerService (void)
	Module service routine, to be called by the main loop().

Utilities

	Set the value of a dimmer channel. More...

Interrupt routine
void	dimmerHighInterrupt (void)
	Module high interrupt routine, must be called by the highInterrupts() user defined function.
void	dimmerLowInterrupt (void)
	Module low interrupt routine, must be called by the lowInterrupts() user defined function.

Receive function
void	dimmerReceive ()
	Module receive function, to be called by the fraiseReceive() user defined function. More...
void	dimmerPrintDebug ()

Function Documentation

dimmerSet()

void dimmerSet	(	unsigned char	num,
		unsigned int	val
	)

Set the value of a dimmer channel.

Parameters

num	Dimmer channel (0 to 7)
val	New 16 bit value for this channel, between 0 and 65535

dimmerReceive()

void dimmerReceive

(

)

Module receive function, to be called by the fraiseReceive() user defined function.

The first byte of the message represents the channel (0-7), the 2 next bytes are the 16 bit new position value. If the first byte is 8 then the next char sets the AC frequency : 0=50Hz, 1=60Hz
