Design of LED Display-Screen System Base on TMS320F2812

Abstract

LED Display-Screen is widely used as one of display Terminals to reveal the information in all aspects. With the improvement of living standards, people demand LED display screen to work with the high quality, high speed and high intelligence. The paper presents a method to design LED display-Screen with TMS320F2812 DSP chip of TI, Meanwhile it uses GPRS to communicate with the telephone and the information platform for convenient remote control, it can constitute a large LED display with the CAN bus and so on. The test shows that the system is reasonable, realizable, operated easily, flexible, adaptable to environment, low price, and it is useful in practice after being proved in the practical system. Key words: Display-Screen;TMS320F2812;DSP ;GPRS;

Design of Full-Color LED Display-Screen System Based on ARM and FPGA

“…The system uses the latest advanced architecture Cortex-M3-based core processor STM32F103ZET6, which is promoted by ST Co. and has a operating frequency of 72 MHz, with 512K FLASH chip integrated, 64K SRAM memory, and up to 13 communication interfaces: two I 2 C, 5 USART, 2 SPI and I 2 S complex, a USB 2.0 full-speed interface, a CAN interface, and an SDIO interface. Various STM32 chip peripherals can simplify the peripheral circuit design and improve the system integration and anti-jamming capability [4].…”

“…The Flowchart of main program as shown in the Figure5. FPGA development process consists in the developing of FPGA chip using Hardware programming language with EDA software and programming tools [4]. Complete FPGA development process includes functional definition, design entry, functional simulation, integration, integration-based simulation, layout wiring, timing simulation, board-level simulation and verification, chip programming and debugging.…”
