GPIO
The nanoX-TCR provides GPIO (General Purpose I/O) pins for custom use through the COM Express A-B
connector. Use the ADLINK Intelligent Device Interface (AIDI) Library to configure the GPIO interface.
AIDI driver information is available in the Utilities link of the nanoX-TCR product page at:
http://www.adlinktech.com
. An AIDI demo program and the AIDI User’s Manual describing how to use the
GPIO pins also reside in the Utilities link of the nanoX-TCR product page.
For more information about GPIO pin operation, refer to the PCA9535BS GPIO Generator Datasheet. Refer
for a hyper link to the datasheet.
