Oceanus-I EV

Overview

The we_oceanus1ev board is an evaluation board of the Oceanus-I [1] radio module. It provides support for the STM32WLE5CC [2] ARM CPU and the following devices:

  • CLOCK

  • FLASH

  • GPIO

  • I2C

  • NVIC

  • RADIO (LoRa)

  • RTC

  • SPI

  • UART

  • WDT

Hardware

The board has below hardware features:

  • Oceanus-I [1], 256KB Flash, 64KB RAM with external antenna

  • 1 FTDI chip (USB to UART) converter

  • 1 I2C WE sensor EV-Boards connector

  • 1 SPI WE sensor EV-Boards connector

  • 2 application LEDs

  • 1 application, and 1 reset push-button

Programming and Debugging

Applications for the we_oceanus1ev board can be built the usual way (see Building an Application).

The board debugged and flashed with an external debug probe connected to the SWD pins, current native support is for the JLink debug probe.

Flashing

Connect the board to your host computer and build and flash an application.

# From the root of the zephyr repository
west build -b we_oceanus1ev samples/hello_world
west flash

Run a serial terminal to connect with your board. By default, lpuart1 is accessible via the on-board FTDI USB to UART converter.

Debugging

You can debug an application in the usual way. Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b we_oceanus1ev samples/basic/blinky
west debug
