Title radar ranging signal with RAM to achieve
Abstract
This paper introduced the general design principle of the data acquisition system, and designed a data acquisition system based on ARM processor.
This system use the chip AT91SAM7S64 as the core, and use the on-chip ADC to collect signals, the TC provides the hardware trigger clock. We use protel to make the hardware schematic diagram and PCB ,and use keil software program to process the data collected. At the last of this paper, the hardware and software debugging methods of the system was given, and tested the system. The result of the test show that the design proposed in this paper is feasible.
