Chapter 3. Executing the Sample Program

3.1 Via the Command Line

Note:

The OS supported by Lanner DIO function include platforms based on Linux Kernel series 2.4.x and

Linux Kernel series 2.6.x, FreeBSD 8.0, and DOS.

This section contains sample executable programs that you could test on your platform.

It demonstrates some useful functionality that the DIO provides. Note that the installation

needs to be completed before proceeding with the execution.

On Linux

The executable program will be in the bin directory after compilation.

Just run “dio_tst” for Digital IO test. This program will drive output pin with specific value

(high or low) and then read status of input pin. If you have external loopback which

connects input to output pins directly, the input value should be identical with output

value.

To execute the DIO sample code, type:

# ./dio_tst

1 2 ... 12 13 14 15 16 17 18 19 20 21 22 ... 27 28
