Detailed Description

Expand 17 Click example.

Description

This example demonstrates the use of Expand 17 Click board by setting and reading the ports state.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration which sets half of pins as output ( IO5, IO6, IO7 and IO8 ) and the half of the pins as inputs ( IO1, IO2, IO3 and IO4 ).

Application Task

Sets the state of the output pins and then reads the status of the input pins and displays the results on the USB UART approximately every 2 seconds.

Note
In order for this example to work as intended it is necessary to connect the input and output pins eg. IO1 and IO5, IO2 and IO6 etc. Floating input pins will be shown as a high state.

< Click config object.

Logger initialization. Default baud rate: 115200 Default log level: LOG_LEVEL_DEBUG

Note
If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
