修改MAC的软件

Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface. PIC Modbus RTU slave supports write and read (3 and 16) functions. The data is stored and read from EEPROM via the I2C bus. You can write/read up to 8000 registers. In a single frame can be read/write 32 registers . The program was written in the HI-TECH C compiler-Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface.

资源描述 经过这几天的学习与调试，终于在STM32F103VCT6+W5500(SPI1)+Freemodbus 平台上，实现Modbus-TCP协议的功能。其实很简单，只要熟悉Modbus-RTU通讯，明白Modbus帧的结构等，Modbus-TCP只是在原来的帧结构上加个头，去个尾，然后用TCP传输即可。 关键的内容就是怎样获取W5500新接收的数据包，并发送给Modbus事件状态机驱动协议的执行，数据的处理。 主要参考Freemodbus demo里的Modbus-TCP协议实现的思路，获取缓存区的读写与发送响应。
