Im working on a project where i going to communicate between a STM32F407VGT and a LTC6804 BMS chip. for communication im going to use SPI with 8Bit datasize. For the communication im going to use a Packet error code which is a 15-bit cyclic redundancy chech (CRC-16) calculation.
sending a message (0x00 0x01) should return CRC value (0x3D 0x6E). I have trid to use the CRC calculation in the SPI driver stm32f4xx_spi.h but i can't figure out how i can initialize the CRC register with a value of: 0x000000000010000.
Has anybody worked with the CRC calculation and knows if this is possible to initialize the crc polynomial calculation?.
Best Regards Helge
It's easy to compute the table. Some programs save flash space by building the table directly after boot.
