Detailed Description

Expand 3 Click Example.

Description

This example demonstrates the use of Expand 3 click board by setting and reading the port state.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

Application Task

Writes a counter data to the port output pins and reads the status of the same port input pins approximately every 500ms. All data are displayed on the USB UART.

Note: The PIO pins are in the open-drain mode, therefore a pull-up resistor must be added to each pin. This click board can be used in a combination with an EasyLED [MIKROE-571] and EasyPULL [MIKROE-575] boards.
