.. zephyr:board:: we_proteus3ev

Overview

The Proteus-III-EV (evaluation board) hardware provides support for the Proteus-III radio module that uses the Nordic Semiconductor nRF52840 ARM Cortex-M4F CPU and the following devices:

:abbr:ADC (Analog to Digital Converter)
CLOCK
FLASH
:abbr:GPIO (General Purpose Input Output)
:abbr:I2C (Inter-Integrated Circuit)
:abbr:MPU (Memory Protection Unit)
:abbr:NVIC (Nested Vectored Interrupt Controller)
:abbr:PWM (Pulse Width Modulation)
RADIO (Bluetooth Low Energy and 802.15.4)
:abbr:RTC (nRF RTC System Clock)
Segger RTT (RTT Console)
:abbr:SPI (Serial Peripheral Interface)
:abbr:UART (Universal asynchronous receiver-transmitter)
:abbr:WDT (Watchdog Timer)

More information about the radio module can be found the Würth Elektronik web page https://www.we-online.com/katalog/de/PROTEUS-III .

Hardware

Proteus-III radio module provides only the internal oscillators. The frequency of the slow clock is 32.768 kHz. The frequency of the main clock is 32 MHz.

Supported Features

.. zephyr:board-supported-hw::

Connections and IOs

LED

LED1 = P0.00
LED2 = P0.01

Push buttons

BUTTON1 = SW1 = P0.03

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the we_proteus3ev/nrf52840 board configuration can be built, flashed, and debugged in the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running.

Flashing

Follow the instructions in the :ref:nordic_segger page to install and configure all the necessary software. Further information can be found in :ref:nordic_segger_flashing. Then build and flash applications as usual (see :ref:build_an_application and :ref:application_run for more details).

Here is an example for the :zephyr:code-sample:hello_world application.

First, run your favorite terminal program to listen for output.

.. code-block:: console

$ minicom -D <tty_device> -b 115200

Replace :code:<tty_device> with the port where the board Proteus-III-EV can be found. For example, under Linux, :code:/dev/ttyACM0.

Then build and flash the application in the usual way.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: we_proteus3ev/nrf52840 :goals: build flash

Debugging

Refer to the :ref:nordic_segger page to learn about debugging Nordic boards with a Segger IC.

Testing the LEDs and buttons in the Proteus-III-EV

There are 2 samples that allow you to test that the buttons (switches) and LEDs on the board are working properly with Zephyr:

.. code-block:: console

samples/basic/blinky samples/basic/button

You can build and flash the examples to make sure Zephyr is running correctly on your board. The button and LED definitions can be found in :zephyr_file:boards/we/proteus3ev/we_proteus3ev_nrf52840.dts.
