Hardware Setup

This page describes the hardware setup for the tallies.
|
||
|
|
How to build the tallies and how to build and flash new firmware to the tallies.
|

|
||
|
|
Build a Tally
|
||
|
|
=============
|
||
|
|
|
||
|
|
For the tallies a classic ``RGB`` ledstrip is used instead of the more modern ``WS2812B`` standard. This ledstrip is connected as follows:

|
||
|
|
Build the firmware
|
||
|
|
==================
|
||
|
|
|
||
|
|
In order to build the firmware a ``Toolchain`` for cross compilation is required.
|
||
|
|
This toolchain is provided in the repository in ``nodemcu-firmware/``.
|
||
|
|
To build the code for the tallies, navigate to ``wifi-tally/tally/`` and run ``make``.
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ make
|
||
|
|
# if it compiles it is syntactically valid
|
||
|
|
../../nodemcu-firmware/luac.cross -o /dev/null src/init.lua

|
||
|
|
|
||
|
|
The resulting files are in the ``out/`` folder.
|
||
|
|
|
||
|
|
Flash the firmware
|
||
|
|
==================
|
||
|
|
To flash the firmware, first put the device in flash mode.
|
||
|
|
You can do this by pressing and hodling the ``FLASH`` button and presing the ``RST`` button.
|
||
|
|
After that you can release the ``FLASH`` button.
|
||
|
|
Next, navigate to ``../wifi-tally/firmware`` and run ``install_firmware.sh``.
|
||
|
|
|
||
|
|

|
||
|

.. note::
|

|
|
If you receive an error about permissions, run ``sudo -E ./install_firmware.sh`` to mitigate permissions for the USB device. Also look in the ``troubleshooting`` section if you keep having issues.
|

|
|
|
||
|
|
Flash the Application
|
||
|
|
=====================
|
||
|
|
Navigate to ``wifi-tally/tally`` and run ``install_application.sh``.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
Make sure to edit the ``out/tally-settings.ini`` for the correct wifi SSID and password.
|
||
|
|
|
||
|
|
.. code:: console
|
||
|
|
|
