Problem STM32 + Si4703 Radio IC

//Read the entire register control set from 0x00 to 0x0F

void readRegisters(){

  unsigned char inBuff[32];

  HAL_I2C_Master_Receive(&hi2c3, SI4703, inBuff, 32, 100);

  //Si4703 begins reading from register upper register of 0x0A and reads to 0x0F, then loops to 0x00.

  //Wire.requestFrom(SI4703, 32); //We want to read the entire register set from 0x0A to 0x09 = 32 bytes.

  //while(Wire.available() < 32) ; //Wait for 16 words/32 bytes to come back from slave I2C device

  //We may want some time-out error here

  //Remember, register 0x0A comes in first so we have to shuffle the array around a bit

  unsigned char i = 0;

  for(int x = 0x0A ; ; x++) { //Read in these 32 bytes

    if(x == 0x10) x = 0; //Loop back to zero

    si4703_registers[x] = inBuff[i] << 8;

    i++;

    si4703_registers[x] |= inBuff[i];

    i++;

    if(x == 0x09) break; //We're done!

  }

}  //<<<< wenn hier durch Breakpoint gestoppt wird und anschließend weitergelaufen lassen wird funktioniert das Radiomodul

//Write the current 9 control registers (0x02 to 0x07) to the Si4703

//It's a little weird, you don't write an I2C addres

//The Si4703 assumes you are writing to 0x02 first, then increments
