# 查找/更新参数
|
||
|
||
PX4 behaviour can be configured/tuned using [parameters](../advanced_config/parameter_reference.md) (e.g. [Multicopter PID gains](../config_mc/pid_tuning_guide_multicopter.md), calibration information, etc.).
|
||
|
||
The _QGroundControl Parameters_ screen allows you to find and modify **any** of the parameters associated with the vehicle.
|
||
The screen is accessed by clicking the **Q** application icon > **Vehicle Setup**, and then _Parameters_ in the sidebar.
|
||
|
||
:::info
|
||
Most of the more commonly used parameters are more conveniently set using the dedicated setup screens, as described in the [Standard Configuration](../config/index.md) section.
|
||
The _Parameters_ screen is needed when modifying less commonly modified parameters - for example while tuning a new vehicle.
|
||
:::
|
||
|
||
:::warning
|
||
While some parameters can be changed in flight, this is not recommended (except where explicitly stated in the guide).

||
|
||
## 查找参数
|
||
|
||
You can search for a parameter by entering a term in the _Search_ field.
|
||
This will show you a list of all parameter names and descriptions that contain the entered substring (press **Clear** to reset the search, and use the **Show modified only** checkbox to filter out unchanged parameters).
|
||
|
||
|
||
|
||
You can also browse the parameters by type and group by clicking on the buttons to the left (in the image below the _DShot_ group in the _Standard_ parameters is selected).
|
||
|
||
|
||
|
||
You can expand/collapse the "type" groupings as shown.
|
||
Note that the groups at the bottom named _Component X_ are attached [DroneCAN peripherals](../dronecan/index.md#qgc-cannode-parameter-configuration) ("X" is the node id).
|
||
[QGC can set the parameters](../dronecan/index.md#qgc-cannode-parameter-configuration) of these peripherals if they are attached to the Flight Controller when QGC is started.
|
||
|
||
|
||
|
||
:::tip
|
||
If you can't find an expected parameter, see the [next section](#missing).

|
||
|
||
## 找不到的参数
|
||
|
||
参数通常不可见，因为它们要么以其他参数为条件，要么不存在于固件中（见下文）。
|
||
|
||
### 条件参数
|
||
|
||
如果一个参数是以未启用的另一个参数为条件，则该参数不会被显示。
|
||
|
||
You can usually find out what parameters are conditional by searching the [full parameter reference](../advanced_config/parameter_reference.md) and other documentation.
|
||
In particular [serial port configuration parameters](../peripherals/serial_configuration.md) depend on what service is assigned to a serial port.
|
||
|
||
### 固件中没有的参数
|
||
|
||
参数可能不在固件中，因为您使用了不同版本的 PX4，或者因为您构建的固件中没有包含相关的模块。
|
||
|
||
每个PX4版本都添加了新参数，现有参数有时被删除或重命名。
|
||
You can check whether a parameter _should_ be present by reviewing the [full parameter reference](../advanced_config/parameter_reference.md) for the version you're targeting.
|
||
您还可以在源代码和发布说明中查找参数。
|
||
|
||
参数可能不在固件中的另一个原因是如果其关联的模块没有被包含。
|
||
This is a problem (in particular) for _FMUv2 firmware_, which omits many modules so that PX4 can fit into the 1MB of available flash.
|
||
解决此问题有两种方法：
|
||
|
||
- Check if you can update your board to run FMUv3 firmware, which includes all modules: [Firmware > FMUv2 Bootloader Update](../config/firmware.md#bootloader)
|
||
- If your board can only run FMUv2 firmware you will need to [rebuild PX4](../dev_setup/building_px4.md) with the missing modules enabled.
|
||
You need reconfigure the PX4 firmware itself through make px4_fmuv2_default boardconfig where you can enabled/disable modules.
|
||
|
||
::: info
|
||
You may also need to disable other modules in order to fit the rebuilt firmware into 1MB flash.
|
||
Finding modules to remove requires some trial/error and depends on what use cases you need the vehicle to meet.

|
||
|
||
## 更改参数
|
||
|
||
要更改参数的值，请单击组或搜索列表中的参数行。
|
||
单击后屏幕侧边会显示一个对话框，您在其中更改参数的值（这个对话框还提供了该参数的额外细节信息——包括是否需要重启才能使参数生效）。
|
||
|
||
|
||
|
||
:::info
|
||
When you click **Save** the parameter is automatically and silently uploaded to the connected vehicle.
|
||
根据参数，您可能需要重新启动飞控才能使更改生效。
|
||
:::
|
||
|
||
## 工具
|
||
|
||
You can select additional options from the **Tools** menu on the top right hand side of the screen.
|
||
|
||
|
||
|
||
**Refresh** <br>Refresh the parameter values by re-requesting all of them from the vehicle.
|
||
|
||
**Reset all to firmware defaults** <br>Reset all parameters to their original default values in the firmware.
|
||
|
||
**Reset to vehicle's configuration defaults** <br>Reset all parameters to their original default values for the particular selected airfame configuration.
|
||
|
||
**Load from file / Save to file** <br>Load parameters from an existing file or save your current parameter settings to a file.
|
||
|
||
**Clear all RC to Param** <br>This clears all associations between RC transmitter controls and parameters.
|
||
For more information see: [Radio Setup > Param Tuning Channels](../config/radio.md#param-tuning-channels).
|
||
|
||
**Reboot Vehicle** <br>Reboot the vehicle (required after changing some parameters).
