This project demonstrates the ADC (Analog-to-Digital Converter).
Requirements
The following evaluation kits are supported by this project:
AT91SAM7A3-EK
AT91SAM7L-EK
AT91SAM7S-EK
AT91SAM7SE-EK
AT91SAM7X-EK
AT91SAM7XC-EK
AT91SAM9260-EK
AT91SAM9G20-EK
AT91SAM9XE-EK
AT91CAP9-DK
AT91CAP9-STK
Description
After launching the program, the device will display the voltage on four of his ADC pins. Somes boards have more than four accessible pins, so the software can be easily update for that.
Usage
For AT91SAM7A3-EK board: The measured pins are J6 pins 1 and 2, and J9 pins B15 and B16
For AT91SAM7L-EK board: The measured pins are J205 pins 1, 3, 5 and 7
For AT91SAM7S-EK board: The measured pins are J7, J8, J9 and J10
For AT91SAM7SE-EK board: The measured pins are J17 pins 29, 30, 31 and 32
For AT91SAM7X-EK board: The measured pins are J16 pins C29 and C30, and J26 pins 1 and 2
For AT91SAM7XC-EK board: The measured pins are J16 pins C29 and C30, and J26 pins 1 and 2
For AT91SAM9260-EK board: The measured pins are J24 pins 1, 2, 3 and 4
For AT91SAM9G20-EK board: The measured pins are J24 pins 1, 2, 3 and 4
For AT91SAM9XE-EK board: The measured pins are J24 pins 1, 2, 3 and 4
For AT91CAP9-DK board: The ADC jumpers are on position 1 (J3)
For AT91CAP9-STK board: The ADC jumpers are on position 3 (J53-3, J54-3, J55-3, J56-3)
Compile the application.
Connect the DBGU port of the evaluation board to the computer and open it in a terminal.
Settings: 115200 bauds, 8 bits, 1 stop bit, no parity, no flow control.
