Appendix A
Sysfs Mapping
LEDs, User Buttons, Digital Input and Digital Output on IGT-30D support Linux sysfs.
The section, Utility Scrip provides a quick access to these peripheral. However,
integrated with users’ own application, it’s also possible to access to these
peripherals via the mapped files. Please refer to the following table for mapping.
