The Sample code source you can download from

Source file: DPC_v3.0L_src.tar.gz

Binary file: DPC_v3.0L_bin.tar.gz

64bits

Source file: DPC_v3.0L_x64src.tar.gz

Binary file: DPC_v3.0L_x64bin.tar.gz

How to compile source code

1. Compile source code with Code::Blocks

Download and install the Code::Block with command "apt-get install codeblocks"

Open an exist project(DPC.cbp) in Code::Blocks, click the compile button


2. Compile source code with "make" 

   Before you make it 

   you need to install make make-guile  pkg-config gcc gtk2.0
  1. cd DPC_v3.0L_src
  1. ./configure
  1. make
  1. src/dpc // execute the binary file

How to use this Demo Application

1. execute the ap, it will showed in system bar

2. Content explanation

3.Frequency of panel selection.


Sample Code Introduction

Define SMBus register 

 typedef unsigned char  BYTE;
 typedef unsigned short WORD;
 typedef unsigned long  DWORD;
 #define m_SMBusMapIoAddr 0x0500
 //----------------------------------------------------------------------------------
 #define HST_STS	0x00	// SMBus Host Status        Register Offset
 #define HST_CNT	0x02	// SMBus Host Contorl       Register Offset
 #define HST_CMD	0x03	// SMBus Host Command 	    Register Offset
 #define XMIT_SLVA	0x04	// SMBus Host Address	    Register Offset
 #define HST_D0	0x05	// SMBus Host Data0         Register Offset
 //----------------------------------------------------------------------------------
 #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);
 }
