PIC 18F2550 I²C Kommunikation XC8 Compiler

Hallo,

void INIT_I2C(void)
  {
    OpenI2C(MASTER, SLEW_OFF);
    SSPADD = 19;
  }

 unsigned int TEST = 0x0000;
 unsigned char LSB = 0x00, MSB = 0x00;

while(1) 
  {
    StartI2C(); // Start condition I2C on bus
    IdleI2C();

    WriteI2C(0x95); // addresses the chip + 1 LESEN
    IdleI2C();
    // AckI2C();

    LSB = ReadI2C(); // read the value from the SLAVE and store in TEST variable.
    IdleI2C();
    // AckI2C();
    MSB = ReadI2C();
    IdleI2C();


    // NotAckI2C(); // Not Acknowledge condition. This will signal the SLAVE that reading data has completed.
    IdleI2C();

    StopI2C(); // Stop condition I2C on bus

    TEST = MSB << 8 | LSB;

    MSB=0x00;
    LSB=0x00;
  } 

Da fehlt doch was oder es ist etwas zu viel?
