摘要
利用PIC16F873片内10位A/D转换器,设计实现了多个按钮开关的数字量输入问题,以此原理制成的16路抢答器,外围电路比较简单,实用性强,而且很容易使之扩展成更多路的抢答器。
Based on the A/D conversion in PIC16F873,this paper solves the input problem of the numerical quantity by button switches, and by this principle, the answer machine with 16 channels has been made. The peripheral circuit of the machine is simple and has a powerful usability, and is easy to be extended to be a multi-channel answer machine.
