摘要
采用美国MICROSHIP公司生产的单片机PIC12C508和美国Xicor公司生产的X9315W设计了一种智能数字电位器。讨论了数字电位器X9315W及PIC12C508单片机的特点,给出了在振荡频率调整应用中二者之间的应用电路,分析了基本的工作原理,并给出了单片机的软件应用程序。它不仅能对电阻数值自动调整,而且体积小、无机械磨损、寿命长,易实现智能化、自动化。
After the discussion on the characteristics of both PIC12C508 and X9315W made respectively in MICROSHIP Co. and XICOR Co. in USA,a intelligent digital rheostat based on above two devices was developed.The application circuit of the two devices in the adjustment of the oscillating frenquency was given,and basic working principle was also analysed.In the end,the application program for monolithic processor was given.The intelligent digital rheostat can not only adjust automatically the value of the resistance,but has such advantadges as small size,non-mechanical wear,long life,intelligence and automation in working.
