DMX master module

Example :

config.h :

#ifndef _CONFIG_H_
#define _CONFIG_H_
 
//DMX config:
#define DMX_UART_NUM    AUXSERIAL_NUM
#define DMX_UART_PIN    AUXSERIAL_TX  // K11 on Versa
#define DMX_NBCHAN      256
 
#endif // _CONFIG_H_
 

main.c :

/*********************************************************************
 *               DMX master example for Versa2
 *  Output DMX frames to AUXSERIAL_TX  (K11 for Versa)
 *********************************************************************/
#define BOARD Versa2
#include <fruit.h>
#include <dmx.h>
 
//----------- Setup ----------------
void setup(void) {  
    fruitInit();            
    DMXInit();        // init DMX master module
}
 
// ---------- Main loop ------------
void loop() {
    fraiseService();// listen to Fraise events
    DMXService();   // DXM management routine
}
 
 
// ---------- Receiving ------------
void fraiseReceive() // receive raw bytes
{
    int i;
    unsigned char c=fraiseGetChar(); // get first byte
    switch(c) {
        PARAM_INT(30,i); DMXSet(i, fraiseGetChar()); break; // if first byte is 30 then get DMX channel (int) and value (char).
    }
}
 

Settings to put in config.h
You must define the serial port : #define DMX_UART_NUM [1/2] #define DMX_UART_PIN [pin]
#define	DMX_NBCHAN
	DMX_NBCHAN default is 128, maybe overloaded up to 256 (TODO:512 but memory issue at compile time when tested).

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

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

Utilities
unsigned int	DMXframeCount
void	DMXSet (unsigned int channel, unsigned char value)
	Set value of a DMX channel. More...

Function Documentation

DMXSet()

void DMXSet	(	unsigned int	channel,
		unsigned char	value
	)

Set value of a DMX channel.

Parameters

channel	DMX channel (starting from 1)
value	New value for this channel (0-255)
