| Abstract: | This paper introduces a design scheme of mass storage equipment used on aeroplane. The hardware and software of mass storage equipment were designed based on ATmega128 MCU, which realizes real-time data communication through RS422, accomplishes 2 GB storage capability by using flash memories and read data from processor at the speed of 10 MB/s via Ethemet port. The program flow and USART are introduced in the paper in detail. |
