| Abstract: | A small-sized LED display system based on the computer and SCM was introduced.The key to design host computer was matrix data acquisition of Chinese character and then sent them to MCU through the infrared serial communication,the lower computer acted as the hardware-driver circuit for LPC900 SCMs and LED screen and made the LED display dynamically.The high performance-price ratio,45×80×3mm3 in dimension and low-power make it be widely used in instruments and serve their on-line display. |
