CameraLED

Pure python3 library to control Camera LED for RaspberryPi 3

Background

This library is used for ArduCAM with motorized IR Cut Filter.
The IR Cur filter is connected to the camera LED, so by controlling the LED you can control the IR filter.
This python library is used to control the camera LED (and IR filter) on Raspberry 3. .

Prerequisites

You have to disable the automatic management of camera led in /boot/config.txt.

$ echo "disable_camera_led=1" | sudo tee -a /boot/config.txt 
$ sudo reboot

Installation

$ wget https://raw.githubusercontent.com/arducam/RPI_Motorized_IRCut_Control/master/CameraLED.py 
$ chmod 755 CameraLED.py

Usage

You need to be root (or at least be able to use sudo).

Standalone

You can use the library as a standalone command:

$ sudo ./CameraLED.py 
Usage: ./CameraLED.py (state|toggle|on|off)

$ sudo ./CameraLED.py state
State: 0

$ sudo ./CameraLED.py toggle
State: 1

$ sudo ./CameraLED.py toggle
State: 0

$ sudo ./CameraLED.py on    
State: 1

$ sudo ./CameraLED.py off
State: 0

For Pi4 with UC350 Rev.B

$ python RPI_Camera_PI4_Ircut_ctl.py on    
State: 1

$ python RPI_Camera_PI4_Ircut_ctl.py off
State: 0

Python library

You can use my library in your Camera projects

from CameraLED import CameraLED
led = CameraLED() # CameraLED(134)
led.on()
led.off()
led.toggle()
led.state()

Photos

LED OFF = NO IR filter = Night vision

LED ON = IR filter = Daily vision
