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

Description

Returns the updated CRC7 value. The CRC7 is left-aligned in the byte (the lsbit is always 0), as that makes the computation easier, and all callers want it in that form.
