.. zephyr:board:: nrf52_vbluno52

Overview

Zephyr can use the nrf52_vbluno52 board configuration to run on the VBLUno52 board, a VNG Bluetooth Low Energy UNO using an nRF52832 ARM Cortex-M4F processor. It provides support for the Nordic Semiconductor nRF52832 ARM Cortex-M4F CPU and the following devices:

:abbr:NVIC (Nested Vectored Interrupt Controller)
:abbr:RTC (nRF RTC System Clock)
UART
GPIO
FLASH
RADIO (Bluetooth Low Energy 5.0)

Hardware

The VBLUno52 board has two external oscillators. The frequency of the slow clock is 32.768 kHz. The frequency of the main clock is 64 MHz.

Supported Features

Connections and IOs

LED

LED = LED0 (green) = P0.12

Push buttons

BUTTON = BUT = SW0 = P0.17

Programming and Debugging

.. zephyr:board-supported-runners::

Flashing

The VBLUno52 board has an on-board DAPLink (CMSIS-DAP) interface for flashing and debugging. You do not need any other programming device. You only need to install the pyOCD tool (https://pypi.python.org/pypi/pyOCD)

See the :ref:getting_started for general information on setting up your development environment.

You can build and flash applications in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.

Testing the VBLUno52 with Zephyr: buttons, LEDs, UART, BLE

Here are some sample applications that you can use to test different components on the VBLUno52 board:

:zephyr:code-sample:hello_world
:zephyr:code-sample:blinky
:zephyr:code-sample:button
:zephyr:code-sample:bluetooth_beacon
:zephyr:code-sample:ble_peripheral_hr
