In the daily life, the calculator application is extremely universal, already became in our daily life the essential computation tool, and further its main part was the one-chip computer. This design introduced the one-chip computer in the calculator domain application technology, take the commonly used MCS-51 series the one-chip computer as a foundation(this time selects 8051), introduced between the one-chip computer and the keyboard as well as with the monitor between application technology simply. In this design keyboard recognition is an extremely important part, this time we use the right and wrong code keyboard, only needs to read in the recognizer in advance, this method causes our hardware
