这是我设计制作的仪表放大器的一个单片机程序。采用C51系列单片机，Keil软件开发环境，用C语言开发，具有液晶显示功能和简单的人机交互界面，主要是用来控制放大器的放大倍数，以满足不同的量程范围。-This is my design of an instrumentation amplifier SCM procedures. Using C51 series microcontroller, Keil software development environment with C-language development, LCD with functional and simple man-machine interface, is mainly used to control the amplifier multiples to meet a range of different areas.
