TRAFFIC LIGHT ControlLER using C51 and RTX-51 tiny，This program is a simple Traffic Light ControlLER. Between start time and end time the system controls a traffic light with pedestrian self-service. Outside of this time range the yellow caution lamp is blinking.
ST7529液晶驅動 The ST7529 is a driver & ControlLER LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
