AN72382 - Using PSoC® 3 and PSoC 5LP GPIO Pins
AN72382 shows you how to use GPIO pins effectively in PSoC® 3 and PSoC 5LP. Major topics include GPIO basics, configuration, mixed-signal use, registers, interrupts, and low-power behavior.
The any-signal-to-any-pin routing available with PSoC® 3 and PSoC 5LP GPIOs helps to optimize PCB layout, shorten design time, and allow a large degree of solderless rework. However, with this freedom comes a steeper learning curve than with a traditional microcontroller. This application note introduces you to PSoC 3 and PSoC 5LP GPIO basics and demonstrates techniques for their effective use in a design.
