Overview

The SAM4L WM-400 Cape is a full featured design to enable IEEE 802.15.4 low power nodes. It is a Beaglebone Black cape concept with an Atmel AT86RF233 radio transceiver. User can develop Touch interface and have access to many sensors and connectivity buses.

Hardware

  • ATSAM4LC4B ARM Cortex-M4 Processor
  • 12 MHz crystal oscillator
  • 32.768 kHz crystal oscillator
  • 1 RS-232 interface
  • 1 RS-485 full duplex interface
  • Micro-AB USB OTG host/device
  • 1 user touch button and One user pushbutton
  • 4 user LEDs
  • 1 AT86RF233 IEEE 802.15.4 transceiver
  • 1 MPL115A2 I²C Barometric Pressure/Temperature Sensor
  • 1 VCNL4010 Proximity/Light Sensor
  • 1 CC2D33S Advanced Humidity Temperature Sensor
  • 1 NCP18WF104J03RB NTC Temperature Sensor
  • 1 TEMT6000X01 Ambient Light Sensor

Supported Features

Connections and IOs

For detailed information see SAM4L WM-400 Cape_ Information.

System Clock

The SAM4L MCU is configured to use the 12 MHz internal oscillator on the board with the on-chip PLL to generate an 48 MHz system clock.

Serial Port

The ATSAM4LC4B MCU has 4 USARTs. One of the USARTs (USART3) is shared between RS-232 and RS-485 interfaces. The default console terminal is available at RS-232 onboard port or via USB device.

Programming and Debugging

.. zephyr:board-supported-runners::

The SAM4L WM-400 Cape board has a 10-pin header to connect to a Segger JLink. Using the JLink is possible to program and debug the SAM4LC4B chip. The board came with a SAM-BA bootloader that only can be used to flash the software.

Flashing

#. For JLink instructions, see :ref:jlink-debug-host-tools.

#. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:/dev/ttyACM0. For example:

.. code-block:: console

  $ minicom -D /dev/ttyACM0 -o

The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:

  • Speed: 115200
  • Data: 8 bits
  • Parity: None
  • Stop bits: 1

#. Connect the SAM4L WM-400 Cape board to your host computer using the USB debug port. Then build and flash the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: sam4l_wm400_cape :goals: build flash

You should see Hello World! sam4l_wm400_cape in your terminal.

#. For SAM-BA bootloader instructions, see :ref:atmel_sam_ba_bootloader.

#. Connect the SAM4L WM-400 Cape board to your host computer using the USB debug port pressing the S1 button. Then build and flash the :zephyr:code-sample:hello_world application. After programming the board the application will start automatically.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: sam4l_wm400_cape :goals: build flash :flash-args: -r bossac

Debugging

You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: sam4l_wm400_cape :maybe-skip-config: :goals: debug
