12+
13+
* :abbr:`ADC (Analog to Digital Converter)`
14+
* CLOCK
15+
* FLASH
16+
* :abbr:`GPIO (General Purpose Input Output)`
17+
* :abbr:`I2C (Inter-Integrated Circuit)`
18+
* :abbr:`MPU (Memory Protection Unit)`
19+
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
20+
* :abbr:`PWM (Pulse Width Modulation)`
21+
* RADIO (Bluetooth Low Energy)
22+
* :abbr:`RTC (nRF RTC System Clock)`
23+
* Segger RTT (RTT Console)
24+
* :abbr:`SPI (Serial Peripheral Interface)`
25+
* :abbr:`UART (Universal asynchronous receiver-transmitter)`
26+

Hardware
39+
********
40+
41+
Proteus-II radio module provides only the internal oscillators. The frequency of the slow clock
42+
is 32.768 kHz. The frequency of the main clock is 32 MHz.

Programming and Debugging
100+
*************************
101+
102+
Applications for the ``we_proteus2ev_nrf52832`` board configuration can be
103+
built, flashed, and debugged in the usual way. See
104+
:ref:`build_an_application` and :ref:`application_run` for more details on
105+
building and running.
106+
107+
Flashing
108+
========
109+
110+
Follow the instructions in the :ref:`nordic_segger` page to install
111+
and configure all the necessary software. Further information can be
112+
found in :ref:`nordic_segger_flashing`. Then build and flash
113+
applications as usual (see :ref:`build_an_application` and
114+
:ref:`application_run` for more details).
115+
116+
Here is an example for the :ref:`hello_world` application.
117+
118+
First, run your favorite terminal program to listen for output.
119+
120+
.. code-block:: console
121+
122+
$ minicom -D <tty_device> -b 115200
123+
124+
Replace :code:`<tty_device>` with the port where the board Proteus-II-EV
125+
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
126+
127+
Then build and flash the application in the usual way.
128+
129+
.. zephyr-app-commands::
130+
:zephyr-app: samples/hello_world
131+
:board: we_proteus2ev_nrf52832
132+
:goals: build flash
133+
134+
Debugging
135+
=========
136+
137+
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
138+
Segger IC.
139+
140+
141+
Testing the LEDs and buttons in the Proteus-II-EV
142+
*************************************************
143+
144+
There are 2 samples that allow you to test that the buttons (switches) and LEDs on
145+
the board are working properly with Zephyr:
146+
147+
.. code-block:: console
148+
149+
samples/basic/blinky
150+
samples/basic/button
151+
152+
You can build and flash the examples to make sure Zephyr is running correctly on
153+
your board. The button and LED definitions can be found in
154+
:zephyr_file:`boards/arm/nrf52dk_nrf52832/nrf52dk_nrf52832.dts`.
