Abstract
A serial peripheral interface (SPI) keyboard module for a parking meter comprises a plurality of key switches and at least one controller configured to detect a key press, determine a predetermined indicator associated with the pressed key and transmit the indicator to a keyboard interface of the parking meter. The SPI keyboard module provides a low power keyboard module that can be easily adapted to provide different keyboards or layouts without requiring significant changes to the parking meter electronics.
