crc7_be(9)

✨ crc7_be(9) ✨

okay bestie, welcome to the Kernel API Manual entry for crc7_be — it's the little function that updates the CRC7 for a data buffer, and yes we're gonna get into it 💅

🌸 NAME 🌸

crc7_be — update the CRC7 for the data buffer

🎀 SYNOPSIS 🎀

u8 crc7_be (u8 crc , const u8 *buffer , size_t len );

💖 ARGUMENTS 💖

• crc — previous CRC7 value
• buffer — data pointer
• len — number of bytes in the buffer

🦋 CONTEXT 🦋

any — literally any context, she's flexible like that 🫶

🔥 DESCRIPTION 🔥

So crc7_be returns the updated CRC7 value. The CRC7 is left-aligned in the byte — the lsbit is always 0 — and that's on purpose, because it makes the computation easier, and all callers want it in that form. No cap. 💅
