CRC Calculator vs ESPHome

CRC Calculator generates cyclic redundancy check byte(s) using the remainder from a polynomial division on the input data. The supported generated check byte(s) are 8, 16, 32 & 64. Data can be manually entered in hexadecimal format or can be sourced from a file that is uploaded through the integrated document explorer. CRC check values can be generated in a normal (most significant bit first) or reversed (least significant bit first) format. This is an essential tool for any developer or software engineer.
