The walnut camera uses two power supply modes: built-in
battery and 5~25.2V external power supply. Supports remote
control of the camera's power on/off, start recording/stop
recording. Take the commonly used flight controller Betaflight
F405 as an example to illustrate how to configure the remote
control to turn on/off the recording function.The wiring
diagram is shown in the figure below, and the TX1 pin on the
flight controller is used to control the recording on/off.

Enter the following blue fonts to configure the PINIO function
of the TX1 pin.
resource SERIAL_TX 1 NONE //Disable the serial port
function of the TX1 pin
resource PINIO 1 A09 //Configure the TX1 pin (The
example is A09 pin, different
flight control pins are different,
please fill in according to the
actual) as PINIO function No. 1
set pinio_box = 40,255,255,255 //Set the PINIO function range
save //save configuration
Next, configure the PINIO function mapping between the remote
controller and flight controller. In Betaflight Configuration, map
the No. 1 PINIO function (ie USER1 in the figure below) to the
AUX channel of the remote control
The trigger mode is a low level trigger, the cursor from the

*KEY信号线可以通过飞控远程控制相机，请阅读相关注意事项
核桃相机使用内置电池与5~25.2V外置电源两种供电方式，支持通
过遥控器远程控制相机开机/关机、开始录像/停止录像。以常用的
穿越机Betaflight F405飞控为例，说明如何配置远程控制开启/关
闭录像功能。接线图如下图所示，使用飞控上的TX1引脚来控制开
启/关闭录像。

通过下面Betaflight CLI命令行，输入以下蓝色字体，配置TX1引脚
的PINIO功能。
resource SERIAL_TX 1 NONE //关闭TX1引脚的串口功能
resource PINIO 1 A09 //将TX1引脚（示例为A09引脚，
不同飞控引脚不同请按实际填写）
配置为1号PINIO功能
set pinio_box = 40,255,255,255 //设置PINIO功能区间
save //保存配置
下面配置遥控器和飞控的PINIO功能映射关系。在Betaflight 地面站
中，将1号PINIO功能（即下图中的USER1）对应到遥控器的AUX通
道。
