Windows CE Library - General Purpose Input Output Library (GPIOLIb)
this is a legacy library and thus not supported by Toradex anymore. We recommend that you use the new libraries for all Toradex modules. Please see the Toradex CE Libraries and Code Samples for up-to-date information.
Description
This library manages General Purpose IO pins.
Current Version
V2.3
Application Notes
The GPIOLib provides functions to interact with GPIO pins - pins can be referenced using SODIMM pin numbers or processor-specifc GPIO pin numbers. Individual functions in the library require a specific type of pin reference type. For portability, SODIMM pin numbers and associated functions are recommended. In some application-specific instances processor-specific GPIO pin numbers will need to be used.
SODIMM pin numbers are numeric. Our datasheets use an alphanumeric format. Conversion between the two formats is detailed here.
Some SODIMM pins have multiple GPIO pins multiplexed on to them - consult the datasheet for your module for specific details.
