本上位机是基于VB语言编程的进行与单片机串口通信的上位机。用于三个舵机的控制。串口通信格式为波特率9600bps、8位数据位、1位停止位、无校验、ASCII码字符通信。串口通信程序用于接收上位机发送过来的控制命令。控制命令采用自定义文本协议，即协议内容全部为ASCII码字符。通信协议格式为起始符“#”通道号CHx，脉宽百位，脉宽十位，脉宽个位，与停止符“!”。-The host computer is based on the VB programming language for serial communication with the PC chip. For three servo control. Baud rate serial communication format is 9600bps, 8 data bits, 1 stop bit, no parity, ASCII, characters communicate. Serial communication program for the PC to receive control commands sent over. Control commands used to customize the text agreement, that agreement contains all ASCII characters. Communication protocol format for the start character " #"　channel number CHx, pulse 100, pulse width ten, pulse width a bit, and stop character " !."
