TMS320F28P650DK: How to Use VCRC for 5-bit CRC Calculation in Endat2.1 Communication?

Part Number: TMS320F28P650DK


Tool/software:

Hello engineers,

I plan to use VCRC to implement the 5-bit CRC calculation for Endat2.1, with the following parameters:

- Initial value: 0x1F

- Polynomial: x^5 + x^3 + x + 1

- Input data: 32-bit, LSB

I have checked the example programs, but why do all the examples generate the corresponding lookup tables?

If all examples use lookup tables, is it also necessary to generate a corresponding lookup table to implement the 5-bit CRC for Endat2.1? And how should I modify the example programs to achieve this?

Regards,

Lin Haonan
