This is a guide to the atod_test C example project included in the EMAC OE SDK.

This application reads 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 (see hardware requirements, below).

The atod_test project builds one executable: indexed_atod_test.

Usage and Behavior

Hardware Requirements

The atod_test project requires a device with indexed atod functionality, ie: A SoM-9260, a SoM-9G20 or an IPAC-9302.
You can also use a SoM-150ES carrier (using the mcp3208 external AtoD device through /dev/mcp3208-gpio. (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)).

Using atod_test

indexed_atod_test DEVICE CHANNELS

Where DEVICE is the path to the device to read and CHANNELS is the number of channels to read.

Usage Example

<syntaxhighlight lang="text"> root@som9g20:/tmp# ./indexed_atod_test /dev/indexed_atod 4 [0] = 19 [1] = 76 [2] = 18 [3] = 22 <syntaxhighlight>
