This system is a DC voltage source for the power supply system, with enhanced 8051 microcontroller-based controllers that STC12C5A60S2 particular, we use this microcontroller NOKIA5110 LCD part and serial data transmission section. Through the keyboard to the required letters and numbers displayed on the LCD, the actual test results demonstrate the system to achieve a standard keyboard to communicate with the microcontroller PS2, read keyboard accuracy.
