|
|
|
<p>Since 2.1.0-rc1 the core includes a Debugging feature that is controllable over the IDE menu.</p>
|
|
|
|
<p>The new menu points manage the real-time Debug messages.</p>
|
|
|
|
<h3 id="requirements">Requirements</h3>
|
|
|
|
<p>For usage of the debugging a Serial connection is required (Serial or Serial1).</p>
|
|
|
|
<p>The Serial Interface need to be initialized in the <code>setup()</code>.</p>
|
|
|
|
<p>Set the Serial baud rate as high as possible for your Hardware setup.</p>
|
|
|
|
<p>Minimum sketch to use debugging:
|
|
```cpp
|
|
void setup() {
|
|
Serial.begin(115200);
|
|
}</p>
|
|
|
|
<p>void loop() {
|
|
}
|
|
```</p>
|
|
|
|
<h3 id="usage">Usage</h3>
|
|
|
|
<ol>
|
|
<li><p>Select the Serial interface for the Debugging messages:
|
|
<img src="debug_port.png" alt="Debug-Port"></p></li>
|
|
<li><p>Select which type / level you want debug messages for:
|
|
<img src="debug_level.png" alt="Debug-Level"></p></li>
|
|
<li><p>Check if the Serial interface is initialized in <code>setup()</code> (see <a href="#requirements">Requirements</a>)</p></li>
|
|
<li><p>Flash sketch</p></li>
|
|
<li><p>Check the Serial Output</p></li>
|
|
</ol>
|
|
|
|
<h2 id="informations">Informations</h2>
|
|
|
|
<p>It work with every sketch that enables the Serial interface that is selected as debug port.</p>
|
|
|
|
<p>The Serial interface can still be used normal in the Sketch.</p>
|
|
|
|
<p>The debug output is additional and will not disable any interface from usage in the sketch.</p>
|
|
|
|
<h3 id="for-developers">For Developers</h3>
|
|
|
|
<p>For the debug handling uses defines.</p>
|
|
|
|
<p>The defined are set by command line.</p>
|
|
|
|
<h4 id="debug-port">Debug Port</h4>
|
|
|
|
<p>The port has the define <code>DEBUG_ESP_PORT</code> possible value:
|
|
- Disabled: define not existing
|
|
- Serial: Serial
|
|
- Serial1: Serial1</p>
|
|
|
|
<h4 id="debug-level">Debug Level</h4>
|
|
|
|
<p>All defines for the different levels starts with <code>DEBUG_ESP_</code></p>
|
|
|
|
<p>a full list can be found here in the <a href="https://github.com/esp8266/Arduino/blob/master/boards.txt#L180">boards.txt</a></p>
|
|
|
|
<h4 id="example-for-own-debug-messages">Example for own debug messages</h4>
|
|

<p>The debug messages will be only shown when the Debug Port in the IDE menu is set.</p>
