Research and Design of the Hardware Platform for the Intelligent Information Bulletin System Based on PXA270

摘要

this article introduced the design and implementation of intelligent information bulletin system based on embedded processor PXA270. System chose Marvell's high-performance embedded processor PXA270 as the core. We designed power management, real-time clock, high-speed USB, SO card, Ethernet, audio, wireless serial port, LCD driver circuit, etc modules, and finally developed the whole hardware platform. We have tested the developed prototype, the actual test result showed that the system had high stability and reliability, and is convenient to use.
