这是VB编程RS232串口（COM口）控制的D/A(数模转换)转换板的上位机演示程序。通过电脑串口（或其他具有串口的单片机、PLC、DSP）发个简单的可视ASCII指令，便可以方便地控制8个数模转换通道输出设定的电压值。比如,电脑串口输出字符串"C2V2660"到本控制板,则控制板将控制2号通道输出2.66V电压；电脑串口输出字符串"C6V3060"到本控制板,则控制板将控制6号通道输出3.06V电压.指令非常简单，完全不需了解复杂的硬件及时序控制。-This is a VB programming RS232 serial port (COM port) control D/A (digital-analog conversion) conversion board host computer demonstration program. Via the computer serial port (or other serial port of the microcontroller, PLC, DSP) made a simple visual ASCII commands, they can easily control the number of eight-channel DAC output set voltage. For example, the computer serial output string " C2V2660" to this control panel, then the control board will control 2-channel output 2.66V voltage computer serial output string " C6V3060" to this control panel, then the control board will control the 6 channel output voltage is 3.06V. instruction is very simple, completely without understanding of complex hardware and timing control.
