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".
     
  3. Select panel what you try to adjust with command "-t". Ex: Select 200 Hz with command "-d0".

   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 "-d0".
   (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 "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".

#define	HST_D0			SMBUSPORT+0x05
#define bSize			1

#define PWMFeq			0x01
#define PWMDuty			0x02

Set Frequency data
