1. DESCRIPTION

This directory contains the driver code for interfacing the AD7689 ADC to the ADSP-BF70x processor
using the SPI port. Both RAC and RDC modes are supported.

****************************************************************************************************
2. VERSION INFORMATION

Tested on:

IDE: CrossCore Embedded Studio 2.1.0.0 (w1508281)
Hardware: ADSP-BF707 EZ-BOARD 1.0

****************************************************************************************************
3. DIRECTORY STRUCTURE

- ADC_7689_Driver -Project directory
 	-src
 		main.c -  Sets up Clock and SPI port and gets data from AD7689 via SPI
		main.h -  Sets up Clock and SPI port and gets data from AD7689 via SPI
		SPI.c   - Configure SPI driver for receiving data from ADC
		SPI.h	- Configure SPI driver for receiving data from ADC
		mode.h  - Switch between RAC and RDC mode flag
	
****************************************************************************************************
4. EXTERNAL CONNECTIONS

   Connect a signal source from a function generator to the J1 port of the ADC using a SMB connector.
   This will convert the signal on CH0.
