Detailed Description

Buck 20 Click example.

Description

This example demonstrates the use of Buck 20 click by changing the output voltage.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables the device.

Application Task

Changes the output voltage every 3 seconds and displays on the USB UART the digipot wiper position, as well as an approximate buck R1 and voltage output.

Note: An approximate buck R1 and VOUT values do not have to be 100% accurate for all wiper settings but they are a good reference point. VOUT ranges from ~1.3V to ~5V, and it is the most accurate around 3.3V since all passive components are set for that output.

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.
