Connections and IOs
|
|
===================
|
|
|
|
LED
|
|
---
|
|
|
|
* LED0 (red) = P0.27
|
|
* LED1 (green) = P0.25
|
|
* LED2 (blue) = P0.26
|
|
|
|
Push buttons
|
|
------------
|
|
|
|
* BUTTON1 = SW1 = P0.25
|
|
* BUTTON2 = SW2 = P0.24
|
|
|
|
General information on module pin numbering
|
|
-------------------------------------------
|
|
|
|
The numbering of the pins on the module and EVK do not follow the GPIO
|
|
numbering on the nRF52832 SoC. Please see the `ANNA-B1 Data Sheet`_ for
|
|
information on how to map ANNA-B1 pins to the pin numbering on the
|
|
nRF52832 SoC.
|
|
|
|
The reason for this is the u-blox module family concept where different
|
|
modules share the same pinout and can be interchanged.
|
|
|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``ubx_evkannab1/nrf52832`` board configuration can be
|
|
built and flashed in the usual way (see :ref:`build_an_application`
|
|
and :ref:`application_run` for more details); however, the standard
|
|
debugging targets are not currently available.
|
|
|
|
Flashing
|
|
========
|
|
|
|
Build and flash applications as usual (see
|
|
:ref:`build_an_application` and :ref:`application_run` for more details).
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
Open a terminal program to the USB Serial Port installed when connecting
|
|
the board and listen for output.
|
|
|
|
Settings: 115200, 8N1, no flow control.
|
|
|
|
Then build and flash the application in the usual way.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: ubx_evkannab1/nrf52832
|
|
:goals: build flash
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Refer to the :ref:`nordic_segger` page to learn about debugging boards
|
|
containing a Nordic Semiconductor chip with a Segger IC.
|
|
|
|
|
|
Testing the LEDs and buttons in the EVK NINA-B11x
|
|
*************************************************
|
|
|
|
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/ublox/ubx_evkannab1/ubx_evkannab1_nrf52832.dts`.
|
|
|
|
Note that the buttons on the EVK-ANNA-B1 are marked SW1 and SW2, which
|
|
are named sw0 and sw1 in the dts file.
|
|
Also note that the SW1 button and the green LED are connected on HW level.
