PIC for the AD converter, and the use of HD7279A display (public cathode of the...

此子程序将进行AD转换和AD处理，处理后的12位AD值中低八位存放在 adc_buffer_low中，高四位存放在adc_buffer_hi寄存器的低四位-This subroutine will convert to AD and AD treatment, treated in the low 12-bit AD value stored in the adc_buffer_low eight, the high four storage registers in the low 4 adc_buffer_hi

基于超声波的测距仪（包括原理图，程序源码与相关调试说明，以及一些参考资料，总之，开发超声波测距仪的一整套资料）-Based on Ultrasonic Range Finder (including schematics, source code and related procedures for debugging instructions, and some reference materials, in short, develop a set of ultrasonic range finder data)

在做一个单片机系统时，常常会遇到这样那样的数据采集，在这些被采集的数据中， 大部分可以通过我们的I/O 口扩展接口电路直接得到，由于51 单片机大部分不带AD 转换 器，所以模拟量的采集就必须靠A/D或V/F 实现。下现我们就来了解一下AD0809与51 单 片机的接口及其程序设计。
