Traffic control arises at the historic moment , it plays an important role in the human life and working environment .People travel all traffic dealt with all the time. An application of the intelligent traffic signal lamp is ARM system ,used in conjunction by the hardware and soft ware. The system adopts the nuvoton technology company ARM Cortex ? - M0 kernel of a new generation of NuMicro32-bit microcontrollers NUC140VE3CN, in with the core of NU - LB - NUC140 NUC140VE3CN development environment for the design of intelligent traffic lights. Is the minimum, the lowest energy consumption , existing on the market the most energy-efficient ARM processor. The processor power consumption is very low, less door number , code to take up the space is little, so widely used, such as electronic measurement, medical equipment, and intelligent control, etc. The design on the NU - LB - NUC140 development board to achieve intelligent traffic lights design, using the BMP graphics conversion tool, using Keil software programming, the results displayed on the LCD screen.
