Example atod

TODO: {{#todo:Review(11.13.13-12:59->JG+)|Jgreene|oe 4,oe 5,ky,md,Review}}

This procedure provides an overview of how to compile and run the atod_test C example project. It assumes familiarity with the C programming language and is intended to be used by experienced programmers who are looking to learn the EMAC SDK.

1. Open the C/C++ editing perspective

From the Eclipse menubar select Window->Open Perspective->Other...

Select C/C++ and click OK.

Figure 1: Select C/C++ Perspective.

2. Open the atod_test project

From the Eclipse menubar select File->New->Makefile Project With Existing Code...

Click the Browse button and navigate to the directory of the atod_test example project.

The atod_test example project source can be found in the projects/ subdirectory of the EMAC OE SDK root directory. The full path is:

    /path/to/sdk/EMAC-OE-arm-linux-gnueabi-SDK_4.0/projects/atod_test/ 

After you have successfully specified the path to the atod_test project directory, click Finish.

3. Build it

This is intentionally left blank pending new build system.

What it does

atod_test reads all channels of an indexed atod device and outputs the results to the terminal.

Usage: indexed_atod_test DEVICE CHANNELS
i.e. : ./indexed_atod_test /dev/indexed_atod 4

From the comments in index_atod_test.c

   Example application for reading all channels of an indexed atod device
   on EMAC OE Linux. Examples of this type of device are the processor
   AtoDs on the SoM-9260/9G20 and the IPAC-9302 and the mcp3208 external
   AtoD devices on the SoM-150ES carrier (through the /dev/mcp3208-gpio
   device. This interface uses the EMAC ioex class to provide a GPIO-like
   device where each channel can be read directly.(see also the egpc project).
