Time-lapse recordOff0.050.10.5135103060sec.Note: Time-lapse is a video recording mode that captures video at a very low frame rate: around one to two frames per second, although this depends on the length of the recording. When played back, time-lapse video is almost the opposite of slow motion. Higher value for shorter video. There’s no voice in this mode.

Triggers:
The trigger pins(Active Low) need to be connected to the trigger control cable. Scan to watch.
Note: Don’t connect the trigger pins to any power. If you want to control it by a MCU, connect it to a 3.3V GPIO through a 1K resistance.

Remote control to record video:
A 2 way switch to control .

www.CNfpv.com

The following example uses Betaflight F405 flight controller to illustrate how to configure the remote control to turn on/off the video recording function. Use the TX1 pin on the flight controller to control the recording and connect the Hawkeye Cam’s TRG PIN(video trigger PIN). If you use other flight controllers, there may be available TX pads instead of TX1, and they may use different resource allocations. You need to adjust the configuration accordingly for your specific flight controller.

Configure the PINIO function of the TX1 pin through the following Betaflight commands.
resource SERIAL_TX 1 NONE // Close the serial port function of TX1 spindle resource PINIO 2 A09 // Configure TX1 pin (A09 pin) as PINIO function No. 2 set pinio_box = 40,41,255,255 // Set the PINIO function interval Save // Save configuration
(If you need to change to other pins, you only need to change the pin number of the first and second lines of instructions, and the instructions of the third and fourth lines remain unchanged.)
The following figure configures the PINIO function mapping relationship between the remote controller and the flight controller. In Betaflight configuration, PINIO No. 2 function (ie USER2 in the figure below) corresponds to the AUX5 channel of the remote control.

To activate or deactivate functions on the camera, you need to move the switch from the inactive state (white area) to the active state (yellow area), and then back to the inactive state (white area). To The switch configuration of the flight controller and radio controller must match the settings of your own device. Before configuring, make sure you know what you are doing. If you are not using the remote control function, please cut off or insulate the yellow and green wires separately, and do not connect them to any location.

Remote control to record video :
NOTE: FC Arm to record, dis-arm to stop recording.

www.CNfpv.com

The following example uses Betaflight F405 flight controller to illustrate how to configure the remote control to turn on/off the video recording function. Use the TX2 pin on the flight controller to control the recording and connect the Hawkeye Cam’s TRG wire (video trigger). If you use other flight controllers, there may be available TX pads instead of TX2, and they may use different resource allocations. You need to adjust the configuration accordingly for your specific flight controller.
Configure the PINIO function of the TX2 pin through the following Betaflight commands.
resource SERIAL_TX 2 NONE // Close the serial port function of TX1 spindle resource PINIO 2 A02 // Configure TX2 pin (A02 pin) as PINIO function No. 2
set pinio_config = 1,129,1,1 // set PINO 2 Reverse output(129), 1 for Forward output
set pinio_box = 40,0,255,255 // Set the PINIO2 as ARM state output Save // MUST Save configuration
(If you need to change to other pins, you only need to change the pin number of the first and second lines of instructions, and the instructions of the third and fourth lines remain unchanged.)
After the settings, the camera will auto record when the drone is armed, and stop recording when it’s dis-armed.

The switch configuration of the flight controller and radio controller must match the settings of your own device. Before configuring, make sure you know what you are doing. If you are not using the remote control function, please do not connect the wires to any location.
