    Abstract
  • In order to increase the display data output rate with the same system cost, an LED display control system based on multiport serial flash was proposed through analyzing the cell boards of the existing bar LED display panels. The system consists of high-speed 1T MCU (micro control unit) of STC12C5616 and multiport serial flash of SST26VF016B with serial peripheral interface (SPI). Based on the SPI high-speed clock of the MCU, the display data in the multi-port serial flash memory is directly sent to a superlong bar LED display panel by the way of direct memory access (DMA). Finally, by taking a 4 09664 monochromatic dot-matrix LED display as an example, the proposed control system was tested. The tested result shows that the display refresh rate is up to 62.5 Hz, and the effectiveness and feasibility of the proposed system are validated.
