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 (see hardware requirements, below) on EMAC OE Linux.

The atod_test project builds one executable: indexed_atod_test.

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).
