How to use the DPC Utility

Image:DPC1.jpg

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

2. It will show the MCU version of DPC.

3. Frequency of panel selection.

4. Apply the frequency of panel which user selected.

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

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

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

11. First key of hotkey. Only enter Ctrl, SHIFT, or ALT.

12. Second key of hotkey. Only enter key: 'A' to 'Z'.

13. Apply the hotkey which user entered.

15. If checked it. utility will adjust the volume of brightness automatically.

16. Light sensor device name.

17. The mode of light sensor in used.

18. The range of light sensor in used.

19. Calculated LUX values.

20. Advanced settings.

Image:DPC5.jpg

21. Choose which mode of light sensor to use.

22. Choose which range of light sensor to use.

23. Custom limit: light sensor maximum volume of brightness.

24. Custom limit: light sensor median volume of brightness.

25. Custom limit: light sensor minimum volume of brightness.

26. Save the setting value but without leaving the window.

27. Save the setting value and close the window.

28. Close the window and without saving.

#define	HST_D0			SMBUSPORT+0x05
#define bSize			1
#define SADD			0xb0
#define PWMFeq			0x01
#define PWMDuty			0x02

SMBusIoWrite 

 void SMBusIoWrite(BYTE byteOffset,BYTE byteData)
 {
     outb( byteData , m_SMBusMapIoAddr + byteOffset);
 }

SMBusIoRead 

 BYTE SMBusIoRead(BYTE byteOffset)
 {
     DWORD dwAddrVal;
     dwAddrVal = inb(m_SMBusMapIoAddr + byteOffset);
     return (BYTE)(dwAddrVal & 0x0FF);
 }

SetDutyCycle 

 void SetDutyCycle(gint iDutyValue)
 {
     DWORD dwPortVal;
     SMBusIoWrite(HST_STS, 0xFE);
     SMBusIoWrite(XMIT_SLVA, SADD);
     SMBusIoWrite(HST_CMD, PWMDuty);
     dwPortVal = SMBusIoRead (HST_STS);
     dwPortVal = dwPortVal & 0x01;
     SMBusIoWrite(HST_D0, iDutyValue);
     SMBusIoWrite(HST_CNT, 0x48);
 }

SetFrequency 

 void SetFrequency(gint iFrequency)
 {
     DWORD dwPortVal;
     SMBusIoWrite(HST_STS, 0xFE);
     SMBusIoWrite(XMIT_SLVA, SADD);
     SMBusIoWrite(HST_CMD, PWMFeq);
     dwPortVal = SMBusIoRead (HST_STS);
     dwPortVal = dwPortVal & 0x01;
     SMBusIoWrite(HST_D0, iFrequency);
     SMBusIoWrite(HST_CNT, 0x48);
 }
