How to use the DPC utility

1. Set step add / subtract brightness level.

2. When click the "LightOff" button, the panel will become darkness.
(*)Hot key and touch position to light on panel must set first.

3. Brightness control scrollbar, you can adjust volume of brightness. Value from 1 to 100.

4. Show the brightness value which you adjust.

5. Advanced config settings.

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

How to set advanced settings of the DPC utility

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

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

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

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

     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();
     }

Set Duty data

     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();
