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.
Contents
1. Open the C/C++ editing perspective
From the Eclipse menubar select Window->Open Perspective->Other...
Select C/C++ and click OK.
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).
