| Abstract: | Based on the technology of embedded real - time operating system and high performance of ARM MPU, a hardware design for LED color screen display control system was designed. Under the control of core chip ARM MPU LPC2214, this control system completed the functions of data store and updating, circulation showing etc. It realized the full color LED screen display a- synchronous control with stable picture, high resolution color, quick refreshing rate and reliable performance. |
