Usage and Behavior

Hardware Requirements

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).
