TMS37157: Communication between TMS3705 and TMS37157

Hi,

I'm almost there, but I need again a little bit of help.

I'd like to calculate the CRC-16 for the communication between TMS3705 and TMS37157 with the CRC module of my MSP430F6659.

I try to use the example code:

 unsigned int i, CRC_Result, CRC_Init = 0x3791;

  // ------------------------< Calculate CRC-16 >-------------------------------
  CRCINIRES = CRC_Init;             // Init CRC
  for(i=0;i<7;i++)                  // Loop
  {
    CRCDIRB = varTMS3705_data[i];   // Input data in CRC
    // __no_operation();
  }
  CRC_Result = CRCINIRES;           // Save results (per CRC-CCITT standard)
  

But the result is wrong.

Any ideas?

Kind regards

Gerd
