E.g. my Epia LT offers 8 programamble GPIO pins according to the documentation (see below for layout) but I'd like to know if there is a driver so I can actually use them and e.g. receive an interrupt when a GPIO goes high or low. Please let us know what is available. Thanks, Udo Epia LT documentation: Digital I/O Connector: DIO General purpose input and output for POS systems.
