16 bit checksum calculator online5/16/2023 ![]() I am trying to confirm if my calculation is correct with some online crc calculators such as:Īccording to the initial and polynomial values that I use, the result should be:Ĭould someone help me understand what is wrong here? Thanks in advance. Printf("result remainder = X \n",remainder) Īnd I call it my main.c: uint8_t crc_buf = Īs you can see from my function call, I pass 0xffff as initial crc value and 0x1021 as polynomial. I have a code that calculates CRC16 uint16_t CalCrc(uint16_t crc_initial, uint8_t* buf,uint16_t len,uint16_t POLY) I have read a few pages that explain what is crc and how to calculate.
