The Sample code source you can download form

Binary file:
???DPCv4.2.2W_bin.zip
???DPC_LightSensor_4.2.2W_bin.zip

How to compile source code

• Compile source code with Code::Blocks.
  1. Download and install the Code::Block with command "apt-get install codeblocks".
     
  2. Open an exist project(DPC_Console.cbp) in Code::Blocks, click the compile button.
     

• Compile source code with "make"
  1. cd DPC_Console
     
  2. key in command "make".
     

   Before you make it, you need to install : "make" "make-guile" "pkg-config" "gcc" "gtk2.0"

How to use the DPC console application

1. Install resource before execute application. ".\install.sh"
   
2. Execute the application. ".\DPC_Console".
   
   
3. Set brightness from 10 to 100 with command "-d". Ex: Set brightness 50 with command "-d50".
   
4. Select panel what you try to adjust with command "-t". Ex: Select 200 Hz with command "-t0".
   (0 = 200 Hz, 1 = 275 Hz, 2 = 380 Hz, 3 = 20 Hz, 4 = 25 Hz)
   
5. Select range what you add / subtract brightness with command "-r". Ex: Select 10 Sz with command "-r4".
   (0 = 1 Sz, 1 = 2 Sz, 2 = 3 Sz, 3 = 5 Sz, 4 = 10 Sz)
   
6. Dump DPC information with command "-i".
   
7. Print DPC help menu with command "-h".
   
8. Step add / subtract brightness with keyboard : "Up arrow key" / "Down arrow key".
   
9. Turn off screen backlight with command "-f". Duty cycle value will be modify to 0.
   
10. Default hot key to turn on screen backlight. With hot key "Ctrl + n". Duty cycle value will be modify to 50.
    
11. Quit DPC application with command "Exit".
    

How to use light sensor module

1. Print light sensor help menu with command "-hl".
   
2. Turn on/off light sensor to modify duty cycle value automaticaly. With command "-la". Ex: Turn off light sensor active with command "-la0".
   (0 = Off, 1 = On)
   Attention: If active light sensor module, GPIO module will be turned off.
   
3. Select light sensor mode with command "-lm". Ex: Select ALS mode with command "-lm0".
   (0 = Measures ALS continuously, 1 = Measures IR continuously)
   
4. Select light sensor range with command "-lr". Ex: Select range 1000 with command "-lr0".
   (0 = 1000, 1 = 4000, 2 = 16000, 3 = 64000)
   
5. Turn on/off using custom bounding range with command "-lc". Ex: Turn on custom bounding range with command "-lc1".
   (0 = Use, 1 = Not use)
   
6. Set a custom value for light sensor maximum range with command "-lmax". Ex: Set 100 for maximum range with command "-lmax9".
   (0 = 10, 1 = 20, 2 = 30, 3 = 40, 4 = 50, 5 = 60, 6 = 70, 7 = 80, 8 = 90, 9 = 100)
   
7. Set a custom value for light sensor median range with command "-lmed". Ex: Set 50 for median range with command "-lmed4".
   (0 = 10, 1 = 20, 2 = 30, 3 = 40, 4 = 50, 5 = 60, 6 = 70, 7 = 80, 8 = 90, 9 = 100)
   
8. Set a custom value for light sensor minimum range with command "-lmin". Ex: Set 10 for minimum range with command "-lmin0".
   (0 = 10, 1 = 20, 2 = 30, 3 = 40, 4 = 50, 5 = 60, 6 = 70, 7 = 80, 8 = 90, 9 = 100)
   

How to use GPIO module

1. Print GPIO module help menu with command "-hg".
   
2. Turn on/off GPIO module to modify duty cycle value. With command "-ga". Ex: Turn off GPIO active with command "-ga0".
   (0 = Off, 1 = On)
   Attention: If active GPIO module, light sensor module will be turned off.
