Design According to the Measurement & Control Platform of the AT91RM9200 Embedded System

Abstract:

In this paper, the design scheme of a Measurement and Control(M&C) system based on AT91RM9200 is proposed. For expanding the test functions, based on the AT91RM9200 control platform the GPIB interface is added in the platform. With the EMAC interface, the automatic test function on multiple communication channels is realized on the GPIB test bus and Ethernet. In this paper, the Modular architecture is used to design the hardware platform. While in the design of the software, the real-time multitasking function of RTOS is combined with the task processing methods corresponding to the interruptions to make the design , building and reusing of tasks more convenient. So that the whole test system can be more common and scalable.
