| Abstract: | 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. |
