###################################################
|

|
||||
Overview
|
||||
********
|
||||
|
||||
The BMD-340-EVAL and BMD-341-EVAL hardware provides support for the
|
||||
u-blox BMD-340 and BMD-341 Bluetooth 5.0 modules, based on the
|
||||
Nordic Semiconductor nRF52840 ARM Cortex-M4F CPU. the BMD-340 and
|
||||
BMD-341 are identical in operation except for the antenna. The
|
||||
BMD-340 has a PCB antenna while the BMD-341 has a U.FL connector.
|
||||
Both support 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:`USB (Universal Serial Bus)`
|
||||
* :abbr:`WDT (Watchdog Timer)`

More information about the BMD-340-EVAL, BMD-340 module, BMD-341-EVAL,
|
||||
and BMD-341 module can be found at the `u-blox website`_.
|
||||
All of the Nordic Semiconductor examples for the nRF52840 DK
|
||||
(nrf52840dk_nrf52840) may be used without modification.
|
||||
|
||||
..note::
|
||||
The BMD-340 and BMD-341 are identical except for the antennna.
|
||||
Throughout this board support package, the filenames utilize
|
||||
the ubx_bmd340eval_nrf52840.
|
||||
|
||||
Hardware
|
||||
********
|
||||
|
||||
The BMD-340 on the BMD-340-EVAL (or BMD-341 on the BMD-341-EVAL)
|
||||
contains an internal high-frequency oscillator at 32MHz.
|
||||
There is also a low frequency (slow) oscillator of 32.768kHz.
|
||||
The BMD-340 and BMD-341 do not include the slow crystal;
|
||||
however, the BMD-340-EVAL and BMD-341-EVAL do.
|
||||
|
||||
.. note::
|
||||
|
||||
When targeting a custom design without a slow crystal, be sure
|
||||
to modify code to utilize the internal RC oscillator for the
|
||||
slow clock.
|
||||
|
||||

Programming and Debugging
|
||||
*************************
|
||||
|
||||
Applications for the BMD-340-EVAL and BMD-341-EVAL board
|
||||
configurations 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
|
||||
========
|
||||
|
||||
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 :ref:`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 BMD-340-EVAL
|
||||
or BMD-341-EVAL 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: ubx_bmd340eval_nrf52840
|
||||
:goals: build flash
|
||||
|
||||
Debugging
|
||||
=========
|
||||
|
||||
Refer to the :ref:`nordic_segger` page to learn about debugging
|
||||
u-blox boards with a Segger J-LINK-OB IC.
|
||||
|
||||
|
||||
Testing the LEDs and buttons in the BMD-340-EVAL and BMD-341-EVAL
|
||||
*****************************************************************
|
||||
|
||||
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/arm/ubx_bmd340eval_nrf52840/ubx_bmd340eval_nrf52840.dts`.
|
||||
|
||||
Using UART1
|
||||
***********
|
||||
|
||||
The following approach can be used when an application needs to use
|
||||
more than one UART for connecting peripheral devices:
|
||||
|
||||
1. Add device tree overlay file to the main directory of your
|
||||
application:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ cat ubx_bmd340eval_nrf52840.overlay
|
||||
&uart1 {
|
||||
compatible = "nordic,nrf-uarte";
|
||||
current-speed = <115200>;
|
||||
status = "okay";
|
||||
tx-pin = <14>;
|
||||
rx-pin = <16>;
|
||||
};
|
||||
|
||||
In the overlay file above, pin P0.16 is used for RX and P0.14 is
|
||||
used for TX
|
||||
|
||||
2. Use the UART1 as ``device_get_binding("UART_1")``
|
||||
|
||||
Overlay file naming
|
||||
===================
|
||||
|
||||
The file has to be named ``<board>.overlay`` and placed in the app
|
||||
main directory to be picked up automatically by the device tree
|
||||
compiler.
|
||||
|
||||
Selecting the pins
|
||||
==================
|
||||
To select the pin numbers for tx-pin and rx-pin:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
tx-pin = <pin_no>
|
||||
|
||||
Open the data sheet for the BMD-340 at the `u-blox website`_, Section 2
|
||||
'Pin definition'. In the table 3 select the pins marked 'GPIO'.
|
||||
Note that pins marked as 'Standard drive, low frequency I/O only
|
||||
(<10 kH' can only be used in under-10KHz applications.
|
||||
They are not suitable for 115200 speed of UART.
|
||||
|
||||
Translate 'Pin' into number for Device tree by using the following
|
||||
formula::
|
||||
|
||||
pin_no = b\*32 + a
|
||||
|
||||
where ``a`` and ``b`` are from the Pin value in the table (Pb.a).
|
||||
For example, for P0.1, ``pin_no = 1`` and for P1.0, ``pin_no = 32``.
|
||||
|
||||
.. note:
|
||||
Pins are defined according to the "nRF52" pin number, not the module
|
||||
pad number.
