Proteus-III-EV

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:

  • ADC

  • CLOCK

  • FLASH

  • GPIO

  • I2C

  • MPU

  • NVIC

  • PWM

  • RADIO (Bluetooth Low Energy and 802.15.4)

  • RTC

  • Segger RTT (RTT Console)

  • SPI

  • UART

  • WDT

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.

Programming and Debugging

The we_proteus3ev board supports the runners and associated west commands listed below.

flash debug

Applications for the we_proteus3ev/nrf52840 board configuration can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application for more details on building and running.

Flashing

Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing. Then build and flash applications as usual (see Building an Application and Run an Application for more details).

Here is an example for the Hello World application.

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

$ minicom -D <tty_device> -b 115200

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

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b we_proteus3ev/nrf52840 samples/hello_world
west flash

Debugging

Refer to the Nordic nRF5x Segger J-Link 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:

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 boards/we/proteus3ev/we_proteus3ev_nrf52840.dts.
