Detailed Description

2x2 key Click example

Description

2x2 Key click has a 4 button keypad and allows multiple key presses.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.

Application Task

This example code demonstrates the usage of 2X2 Key Click board. Detects whether any of the keys is pressed where results are being sent to the UART terminal where you can track changes.

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.
