| Abstract: | MCS-51 system is mostly controlled with keys.h must be considered for designers which are eliminating the dithering of keys and operating respond of keys in non- coding keyhoard.in this thesis, the dithering problem of keys was solved by software and discussed how to come true once key operation of respond. In addition,some applied procedures were provided with C51 language in the paper. |
