32-Bit Operating Systems
Kontron Embedded Modules GmbH offers a 32bit API (JIDA32), which also includes protected mode
functions to read and write the GPIOs. This programmer’s interface is available for the major 32-bit
operating systems and can be downloaded from the Kontron Web site.
Detailed programming information about JIDA32 is beyond the scope of this document. Please refer to
the JIDA32 documentation and the sample code, which is part of the JIDA32 package on the Kontron
Web site.
