Design method of infrared information processing hardware platform based on TMS320F2812

The design of hardware platform are very important designing method of infrared information processing hardware for processing infrared information. The paper introduces a platform which is based on TMS320F2812. The platform has ten sampling channels, automatic gain control circuit and kinds of D/A conversion circuit. This paper discusses the capability and elements of TMS320F2812, and gives the designing of peripheral and external interface circuits, and the designing of driving program. The last give the experiments of the platform. The results of the experiment show that the platform can satisfy the requirement of system. The platform has good stabilization and dependahility.
