okay so this is a Kernel API Manual page, bestie — section 9, main character energy, and we're talking about one tiny but iconic checksum function. no cap ✨

✨ NAME ✨

atmel_i2c_checksum — generate a 16-bit CRC as required by ATMEL ECC. It's doing CRC16 verification of the count, opcode, param1, param2 and data bytes. The checksum is saved in little-endian format in the least significant two bytes of the command. The CRC polynomial is 0x8005, and the initial register value should be zero. periodt 💅

🦋 SYNOPSIS 🦋

void atmel_i2c_checksum (struct atmel_i2c_cmd *cmd );

🎀 ARGUMENTS 🎀
