<div class="section" id="tools">
<h2>Tools<a class="headerlink" href="#tools" title="Permalink to this headline"></a></h2>
<p>I use the following tools in order to build and manage the software:</p>
<ul class="simple">
<li><p>Visual Studio Code</p></li>
<li><p>PlatformIO</p></li>
<li><p>Git for Windows</p></li>
<li><p>VSCode plugin: Minify (used to minimise the html files)</p></li>
</ul>
</div>
<div class="section" id="code-formatting">
<h2>Code Formatting<a class="headerlink" href="#code-formatting" title="Permalink to this headline"></a></h2>
<p>I use pre-commit and their cpp style checks to validate the code. Plugin defintions are found in <strong>.pre-commit-config.yaml</strong></p>
<p><a class="reference external" href="https://www.pre-commit.com">Pre-Commit</a></p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>There is not yet any automatic checks since this does not work on Windows. It works if running under WSL2 with Ubuntu.</p>
</div>
</div>
<div class="section" id="targets">
<h2>Targets<a class="headerlink" href="#targets" title="Permalink to this headline"></a></h2>
<p>In the platformio config there are 3 targets defined</p>
<ul class="simple">
<li><p>gravity-debug; Maximum logging for trouble shooting, deep sleep is disabled.</p></li>
<li><p>gravity-release; Standard release</p></li>
<li><p>gravity-perf; Standard release but contains code for measuring performance.</p></li>
<li><p>gravity32-release: Version for ESP32.</p></li>
<li><p>gravity32-perf: Version for ESP32 but contains code for measuring performance.</p></li>
</ul>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>There is an experimental ESP32 target but since platformio only supports SDK 1.0.6 and the WIFI connection is really slow compared to ESP8266,
so the recommendation is to wait for support on 2.0.x branch. With the tested version an wifi connection takes 3-8s on a ESP32 compared
to 0.5s on an ESP8266. There is also a bug in OneWire connected to ESP32 that has not been fixed in the main repository yet.</p>
</div>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>The debug target can be unstable and crash the device under certain circumstanses. Excessive logging to the serial port can cause corruption and crashes.
So only enable enough debugging to troubleshoot your changes.</p>
