Hallo,
ich habe meinen RP6 gerade mit ein paar Wärmesensoren ausgestattet.
Diese werden über die M32 ausgewertet.
Soweit läuft alles, aber jetzt wollte ich die Bumper mit ins Programm einfügen.
Leider reagieren die nicht!
Was mache ich falsch.
Hier der Quellcode.
Code:
// Includes:

#include "RP6ControlLib.h"
#include "RP6I2CmasterTWI.h"	
#include "RP6Control_I2CMasterLib.h"

/*****************************************************************************/
#define I2C_RP6_BASE_ADR 10

// I2C Requests: 

/**

 */
void I2C_requestedDataReady(uint8_t dataRequestID)
{
	checkRP6Status(dataRequestID);
}

	}
