How to compile source code
(Develop Environment: UBUNTU 18.04)
- Step1: Install compile packages
- Install "GCC Ver.7.5.0". You could install "build-essential" include it.
Command: "apt install build-essential".
- Install "gtk2.0".
Command: "apt install libgtk2.0-dev".
- Step2: Compile source code with CodeBlocks.
- Download and install the "CodeBlocks".
Command: "apt-get install codeblocks".
- Open an exist project(DPC_Console.cbp) in CodeBlocks, click the compile button.
- Open an exist project(DPC_Console.cbp) in CodeBlocks, click the compile button.
- Or compile source code with "make"
- cd DPC_Console
- cd DPC_Console
Command: "make".
How to use the DPC console application
- Install resource before execute application. ".\install.sh"
- Execute the application. ".\DPC_Console".
- Dump DPC information with command "-i".
- Print DPC help menu with command "-h".
- Set brightness from 10 to 100 with command "-d". Ex: Set brightness 50 with command "-d50".
- 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)
- 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)
- Step add / subtract brightness with keyboard : "Up arrow key" / "Down arrow key".
- Turn off screen backlight with command "-f". Duty cycle value will be modify to 0.
- Fixed hot key to turn on screen backlight with hot key "Ctrl + n". Duty cycle value will be modify to 50.
- Clear terminal screen with command "Clear".
- Quit DPC application with command "Exit".
If you have LEX light sensor module. How to use light sensor module
- Print light sensor help menu with command "-hl".
- 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.
- Select light sensor mode with command "-lm". Ex: Select ALS mode with command "-lm0".
(0 = Measures ALS continuously, 1 = Measures IR continuously)
- Select light sensor range with command "-lr". Ex: Select range 1000 with command "-lr0".
(0 = 1000, 1 = 4000, 2 = 16000, 3 = 64000)
- Turn on/off using custom bounding range with command "-lc". Ex: Turn on custom bounding range with command "-lc1".
(0 = Use, 1 = Not use)
- 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)
- 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)
- 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)
Sample code Introduction
Step1. Initial SMBUS.
if( SMBus_Install() == false ) printf( "Initial SMBUS failed!!! \n" );
Step2. Check DPC device is exist from SMBUS.
#define DPC_ADD 0xb0
if(!SMBus_CheckDevice(DPC_ADDR)) printf( "DPC device is not exist!!! \n" );
Step3. Setup frequency type of panel.
#define PWMFeq 0x01 BYTE pbCmd = PWMFeq;
(itype = 1: 200 Hz, itype = 2: 275 Hz, itype = 3: 380 Hz, itype = 4: 20 Hz, itype = 5: 25 Hz) int nValue = itype;
if(SMBus_WriteByte( DPC_ADDR, pbCmd, (BYTE)nValue ) == true) printf( "Setup panel type success. \n" );
If you need to get current frequency type of panel.
BYTE byteCmd = PWMFeq; BYTE byteVale = 0x0;
SMBus_ReadByte(DPC_ADDR, byteCmd, &byteVale);
Step4. Setup DPC brightness level.
BYTE pbCmd = PWMDuty;
(iduty = level 0 ~ 100) int iduty = 50;
if(SMBus_WriteByte( DPC_ADDR, pbCmd, (BYTE)iduty) == true) printf( "Setup brightness level success. \n" );
If you need to get current brightness level.
BYTE byteCmd = PWMDuty; BYTE byteVale = 0x0;
SMBus_ReadByte(DPC_ADDR, byteCmd, &byteVale);
Final Step. Release SMBUS resource before closing program.
SMBus_Uninstall();
