A naive CRC implementation in C Code Cleanup Before we start making this more efficient, the first thing to do is to clean this naive routine up a bit. In particular, let's start making some assumptions about the applications in which it will most likely be used. First, let's assume ...
modbus-crc16——c语言 为确保消息数据的完整性,除了验证消息CRC之外,建议实现检查串行端口(UART)成帧错误的代码。如果接收消息中的CRC与接收设备计算的CRC不匹配,则应忽略该消息。下面的C语言代码片段显示了如何使用逐位移位和异或运算来计算Modbus消息CRC。使用消息帧中的每个字节计算CRC,除了包含CRC本身的最后两个字...

The pycrc program generates *.h and *.c files containing C99 code with the following definitions: crc_t crc_init(void); crc_t crc_update(crc_t crc, const void *data, size_t data_len); crc_t crc_finalize(crc_t crc); This library converts the C99 code in the following way: each...
