# Display

The display shows all kinds of battery information presented on an optional local I2C LCD display (e.g. SSD1306 type). The display should be connected to J23. 

{% hint style="info" %}
Both 3.3V and 5V are supported for the display. You can change the display voltage. For example to enable 3.3V on the display connector J23, make sure **D34** is **placed** and **D35** is **not placed**! \
\
If the diode D35 is placed, move the diode placed on D35 and place it on D34.
{% endhint %}

There is a framebuffer which makes sure the data is transferred to the display. Information like SoC, SoH, output status, BMS mode, battery voltage, average current, temperature and ID can be seen on the display.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://nxp.gitbook.io/rddrone-bms772/software-guide-nuttx/display.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
