EZ-PSoC Library
Cypress Semiconductor Corporation provides an easy and useful software tool - PSoC Creator. PSoC Creator is an Integrated Design Environment (IDE) that allows concurrent hardware and application firmware design of PSoC 3, PSoC 4 and PSoC 5 systems. PSoC Creator incorporates over hundred on-chip components, so developers can easily drag-and-drop the necessary component into their design and configure that component to suit a broad array of application requirements. PSoC Creator will also generate API libraries for each component; hence the user can directly access components and easily perform reconfiguration during the run-time.
