How to use the DEMO application

When the DPC utility starts, it will hide in the notification area (like below picture),
and double click the tray icon (shown as the red square below), 'DPC v4.2.3w', it will show.

1. Frequency of panel selection.

2. Apply the frequency of panel which user selected.

3. If checked to save DPC setting , the setting of frequency and duty cycle will be reserved.

4. It will show the MCU version of DPC.

5. Brightness control scrollbar, you can adjust volume of brightness.

6. Show the brightness value which you adjust.

7. When click the LightOff button, the panel will become darkness.

8. Set step add / subtract brightness unit.

9. Apply the step unit.

10. Reset the record of hot key and picked up area.

11. Click the button. User can pick up the area from object 13. When clicking area, the panel will be light on from darkness.

12. Click the button. User can set the hotkey. When push hot key, the panel will be light on from darkness.

13. The light on mouse position and hotkay can not use together , after you record hotkey , you can't use the position anymore.

13. First key of hotkey

15. Second key of hotkey

16. Third key hotkey

17. Confirm the hotkey which you entered

18. Show hotkey which you set.

19. Hotkey will show here.

20. If you want to exit DPC , you should click right button of mouse on the icon and choose exit.

21. Check this grid program will automatically grab the light size to adjust the DPC light and dark

22. Showing the device name

23. Showing the mode in use

24. Showing the range in used

25. Showing calculated LUX values

26. Mode and Range detail settings

27. Choose which mode to use

28. Choose which range to use

29. Custom DPC Max brightness

30. Set the DPC brightness intermediate reference value

31. Custom DPC Min brightness

32. Complete the settings button but without leaving the window

33. Complete the settings button and exit leaving the window

34. exit leaving the window

Sample code Introduction

Define SMBus register

#define SMBUSPORT		0x0500
#define	HST_STS			SMBUSPORT+0x00
#define	HST_CNT			SMBUSPORT+0x02
#define	HST_CMD			SMBUSPORT+0x03
#define	XMIT_SLVA		SMBUSPORT+0x04
#define	HST_D0			SMBUSPORT+0x05
#define bSize			1
#define SADD			0xb0
#define PWMFeq			0x01
#define PWMDuty			0x02

Set Frequency data

DWORD dwPortVal;

if (bResult){
     SetPortVal(HST_STS, 0xFE, bSize); //start
     Sleep(20);
     SetPortVal(XMIT_SLVA, SADD, bSize); //set
     Sleep(20);
     SetPortVal(HST_CMD, PWMFeq, bSize); //set frequency
     Sleep(20);
     GetPortVal(HST_STS, &dwPortVal, bSize);
     Sleep(20);
     dwPortVal = dwPortVal & 0x01;
     if (dwPortVal == 0){
          SetPortVal(HST_D0, fvalue, bSize); //write data into frequency
          Sleep(20);
          SetPortVal(HST_CNT, 0x48, bSize); //stop
          Sleep(20);
          ShutdownWinIo();
     }
     else
          ShutdownWinIo();
}
ShutdownWinIo();

Set Duty data

UpdateData(TRUE);
DWORD dwPortVal;
bool bResult;
bResult = InitializeWinIo();

if (bResult){
     SetPortVal(HST_STS, 0xFE, bSize); //start
     Sleep(20);
     SetPortVal(XMIT_SLVA, SADD, bSize); //set 
     Sleep(20);
     SetPortVal(HST_CMD, PWMDuty, bSize); //set duty
     Sleep(20);
     GetPortVal(HST_STS, &dwPortVal, bSize);
     Sleep(20);
     dwPortVal = dwPortVal & 0x01;
     if (dwPortVal == 0){
          if (inverter == false)
               SetPortVal(HST_D0, dvalue * 10 , bSize); //write data into data
          else if (inverter == true)
               SetPortVal(HST_D0, (10 - dvalue) * 10 , bSize); 
          Sleep(20);
   	   SetPortVal(HST_CNT, 0x48, bSize); //stop
          Sleep(20);
          ShutdownWinIo();
     }
     else
          ShutdownWinIo();
}
ShutdownWinIo();
