6.2 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 2 standard assigns the following pins for either GPI or GPO

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
