2.2.12 Functional Switches and Status LEDs

There are two functional multipurpose push buttons connected to GPIOs configured as inputs on the processor that can be used for software developers to test applications developed using this board. Three LEDs are connected to three GPIOs of the processor to indicate the status of processes that are running, completed, or can have failed. Both the push-buttons and status LEDs can be used for debugging or to provide tactile inputs and visual feedback to the user. These connections are shown in Figure 2-12.
