Design and Implementation of LED Display Screen Controller Based on STM32 and FPGA

Abstract

In order to realize point-light-source and hurdle lamp LED displays system, a kind of LED display screen controller design based on FPGA and STM32 is introduced by this paper. This design can quickly and easily receive display the data from USB, Ethernet and SD card interfaces through the STM32 processor, and use FPGA to realize data transmission throughput big operation of stable display by double RAM Ping-Pong operation This paper gives drive unit timing for TM1809 series LED drive chip as typical case. This design has applied to LED display controller with stability of reading data and excellent performance.

Design of wave control system based on Ka phased array AIP antenna

“…With the development of technology and the increase of system functions, the scale of phased array antennas is getting larger and their working modes are becoming more and more complex, requiring higher requirements for wave control linking system [7][8][9][10] .…”

A Design of FPGA-Based Interpolator on Digital Integration

“…Furthermore, it is also available for online technological upgrading job, being truly favorable for the CNC machine tools to achieve interpolation algorithm with machining accuracy and speed to be fully guaranteed. This is particularly effective to complete the seamless continuous processing of tiny contour segments to achieve universal performance indicators of the CNC system [3][4][5][6][7].…”

Microstructure and Optical Properties of Fluorocarbon Films Deposited by Pulsed Plasma Thruster

“…Our previous research revealed [7][8] that the content of fluorine and the type of fluorocarbon groups in the layer of the carbon film influence the film properties to a great extent. To reveal the characteristics of the PPT plume, the microstructure and composition of these films were investigated with X-ray photoelectron spectroscopy.…”
