5.2. GPIO
GPIO library support is limited to GPIO signals that originate from the Computer on Module and extend to the carrier board. COM Express
modules support 4 GPO and 4 GPI signals. Some of ADLINK’s COM Express boards can configure all 8 ports for GPI or GPO use.
GPIO signals can be monitored and controlled by using the ADLINK Intelligent Device Interface (AIDI) library that is compatible and identical
across all ADLINK COM Express modules and all supported operating systems.
The COM Express Type 6 standard assigns the following pins for either GPI or GPO.

5.2.1. AIDI Demo Program - GPIO Tab
The AIDI Demo Program displays current GPI
or GPO status and allows reading of GPI and
writing to GPO.
The table above links logical port numbers in
AIDI to physical port numbers on the COM
Express board-to-board connector.
For boards that support multi-direction the
“SetDirection” button can configure the port for
either GPI or GPO
