Das erste Mal ein richtiges Programm sehen

[ActiveRobo]

Und hier nochmal eins in C für Cypress Chips:

//----------------------------------------------------------------------------
// C main line
//----------------------------------------------------------------------------

#include <m8c.h>        // Part specific Constants and Macros
#include "PSoCAPI.h"    // PSoC API definitions for all User Modules

char Button = 0x00;

void I2C_Init(void);

void main(void)
{
  M8C_EnableGInt;
  CSD_Start(); 
  CSD_InitializeBaselines();
  CSD_SetDefaultFingerThresholds(); 
  
  EzI2Cs_SetRamBuffer(1, 1, (char *)&Button);

  I2C_Init();

  while (1)
     {
    CSD_ScanAllSensors();
    CSD_UpdateAllBaselines();
        
        // Sensor 1
        if(CSD_bIsSensorActive(0))
        {
            PRT2DR |= 0x01;
            Button = 0x01;
        }
        else
        {

        }

        if(CSD_bIsSensorActive(1))
        {

            Button = 0x02;

        else
        {

        }
    }
}

void I2C_Init(void)
{

}

Und wofür war das gedacht? Was hast du da geschrieben?
