| Abstract: | The display is a 16 × 16 two-color LED dot matrix, with AT89Sb2 MCU as mare controller crop ann 74HC595 data scanner, drived by 74HC154 and 9012PNP triode. There are four basic keys, a buzzer and program download module. It can be used not only as screen but also as development board and support the download of 51 chips serial. Meanwhile, it is possible to make circle display of Chinese characters or pictures, to show by scrolling up and down around. The most functions of the system is achieved through software, with chararacteristics of simple circuit and systemantic reliability. |
