Description: Procedure Description: First, a development environment, development board: AT91SAM7X256-EK 2, emulator: SAM-ICE (ATMEL) 3, development of software: IAR4_30A-1_2 (IAR) 2, the program features one, the program Objective: To introduce AT91SAM7X256 ADC' s Basic Usage: 2, Function Description: ADC test- with ADC0_AD3 as analog switch 3, the board set up one, based on AT91SAM7X256-EK using the wizard, set a good development board (minimum system). 2, J13 1,2 feet shorter then , choose the output voltage of MN2 as the ADC' s reference voltage 3, run the program, using wire to J26 of the two-port connected with the ground (0V analog input voltage), we can see LED0 eliminate, LED1 light. 2-port with a port connected to (3V analog input voltage) can be seen LED1 eliminate, LED0 bright.
