103转modbus协议C程序，支持多个485端口并能够配置(103 turn modbus protocol C program, more than 485 ports and supports the ability to configure)

逆变器主程序 和通讯程序 、中断程序、算法及主要编程代码 希望能够帮助大家(The main program and communication program, interrupt program, algorithm, and main programming code of the inverter are expected to help you)

说明：  实现optisystem中matlab component的ofdm仿真。这是调制代码 解调代码在另一个程序里。(Realize ofdm simulation of matlab component in optisystem. This is the modulation code. The demodulation code is in another program.)

说明：  关于VC编写的一份串口通讯程序，测试已通过(VC prepared on a serial communication program, test has passed)
