Introduction

Power Board Develop Utility can help you to develop tool to control LEX power board device.

Support power board module

PW405、PW407、PW601.

The binary file you can download from

DLL files descreption

PWUtilityDll.dll: Contains code and data about PWUtilityDll function.

PWUtilityDll.h: Header about PWUtilityDll function.

PWUtilityDll.lib: Import library that link to PWUtilityDll.dll.

LexIo64.dll、LexIo64.sys: Based on WinIO that provids DLL to read hardware data. For x64.

How to use DLL

*Step1. Unzip DLL zip file and put files to your programe.

*Step2. Initialize power board module resource.

PW_MODULE_E defined in PWUtilityDll.h

 enum PW_MODULE_E
 {
     PW_MODULE_PW405 = 0,
     PW_MODULE_PW407,
     PW_MODULE_PW601,
     PW_MODULE_NUM,  //Used to record the number of modules
 };

 //------------------------------------------------------------------------------
 // Name        : PW_InstallPwModule
 // Description : Initial PW module resource
 // Arguments   : 
 //   nModule     [in]  : PW module. Enum of PW_MODULE_E.
 // Return      : 
 //   TRUE  : Success
 //   FALSE : Failed
 //------------------------------------------------------------------------------ 
 PWUTILITYDLL_API int PW_InstallPwModule(int nModule);

*Step3. You could call PW_CheckPWModuleExist() to check device is still exist or not.

 //------------------------------------------------------------------------------
 // Name        : PW_CheckPWModuleExist
 // Description : Check specific PW module exist or not.
 // Arguments   : 
 //   nModule [in] : PW module. Enum of PW_MODULE_E.
 // Return      : 
 //   TRUE  : PW module exist
 //   FALSE : PW module does not exist
 //------------------------------------------------------------------------------ 
 PWUTILITYDLL_API int PW_CheckPWModuleExist(int nModule);

*Step4. If you want Send DO signal once. Use 1 byte to indicate the digital output pins to be triggered.

Digital output pin bit is 1; Digital input pin bit is 0.
(DO-0 is bit4, DO-1 is bit5, DO-3 is bit6 and DO-3 is bit7).

Ex: Send CIO DO-0、DO-1、DO-2、DO-3 DO signal. bDOVal = 0xF0 (1111 0000) => (OOOO xxxx).
Ex: Send CIO DO-0、DO-3 DO signal. bDOVal = 0x90 (1001 0000) => (OxxO xxxx).

 //--------------------------------------------------------------------------
 // Name        : GPIODLL_SendDOValueToControlModule
 // Description : Send digital out value to GPIO device module
 // Arguments   : 
 //   nModule [in] : GPIO device module. Enum of MODULE_GPIO_LIST_E.
 //   nSwPort [in] : Enum of GPIO_CIO_PORT_E
 //   bDOVal  [in] : Digital out value
 // Return      : 
 //   TRUE  : Success
 //   FALSE : Failed
 //--------------------------------------------------------------------------
 GPIOUTILITYDLL_API int GPIODLL_SendDOValueToControlModule(int nModule, int nSwPort, BYTE bDOVal);

*Step5. If you want receive DI signal once. Use 1 byte to indicate the digital input pins status.

If digital input pin trigger, bit is 1; Else bit is 0. Digital output pin bit is always 1.
(DI-0 is bit0, DI-1 is bit1, DI-2 is bit2 and DI-3 is bit3).

Ex: Receive bDIVal = 0xFF. If DI/DO is 0xF0 (OOOO IIII), then DI-0、DI-1、DI-2、DI-3 are triggered.
Ex: Receive bDIVal = 0xF9. If DI/DO is 0xF0 (OOOO IIII), then DI-0、DI-3 are triggered.

 //--------------------------------------------------------------------------
 // Name        : GPIODLL_GetDIValueFromControlModule
 // Description : Get digital in value from GPIO device module
 // Arguments   : 
 //   nModule  [in] : GPIO device module. Enum of MODULE_GPIO_LIST_E.
 //   nSwPort  [in] : Enum of GPIO_CIO_PORT_E
 //   bDIVal  [out] : Digital in value
 // Return      : 
 //   TRUE  : Success
 //   FALSE : Failed
 //--------------------------------------------------------------------------
 GPIOUTILITYDLL_API int GPIODLL_GetDIValueFromControlModule(int nModule, int nSwPort, BYTE &bDIVal);

*Step6. If you want enable WDT coutdown function and trigger shutdone after few seconds later.

You could update the trigger time by calling GPIODLL_StartWatchDogTimer() repeatedly.\n");

 //--------------------------------------------------------------------------
 // Name        : GPIODLL_StartWatchDogTimer
 // Description : Start running watch dog timer in device module.
 // Arguments   : 
 //   nModule [in] : GPIO device module. Enum of MODULE_GPIO_LIST_E.
 //   nUnit   [in] : Time unit (0: 1sec, 1: 60 sec)
 //   nCount  [in] : Watch dog timer range.(0~255)
 // Return      : 
 //   TRUE  : Success
 //   FALSE : Failed
 //--------------------------------------------------------------------------
 GPIOUTILITYDLL_API int GPIODLL_StartWatchDogTimer(int nModule, int nUnit, int nCount);

*Step7. If you want to know WDT countdown remaining seconds.

 //--------------------------------------------------------------------------
 // Name        : GPIODLL_GetWatchDogCountdownSeconds
 // Description : Get watch dog timer countdown time in device module.
 // Arguments   : 
 //   nModule    [in] : GPIO device module. Enum of MODULE_GPIO_LIST_E.
 //   nTimerSec [out] : Countdown time seconds.(0~255)
 // Return      : 
 //   TRUE  : Success
 //   FALSE : Failed
 //--------------------------------------------------------------------------
 GPIOUTILITYDLL_API int GPIODLL_GetWatchDogCountdownSeconds(int nModule, int& nTimerSec);

*Step8. If you want disable WDT coutdown function.

 //--------------------------------------------------------------------------
 // Name        : GPIODLL_StopWatchDogTimer
 // Description : Stop watch dog timer in device module.
 // Arguments   : 
 //   nModule  [in] : GPIO device module. Enum of MODULE_GPIO_LIST_E.
 // Return      : 
 //   TRUE  : Success
 //   FALSE : Failed
 //--------------------------------------------------------------------------
 GPIOUTILITYDLL_API int GPIODLL_StopWatchDogTimer(int nModule);

*Final Step. Release GPIO resource before leaving your program.

 //------------------------------------------------------------------------------
 // Name        : GPIODLL_FreeControlModule
 // Description : Free DLL supported GPIO device module.
 // Arguments   : 
 //   nModule [in] : GPIO device module. Enum of MODULE_GPIO_LIST_E.
 // Return      : 
 //   TRUE  : Success
 //   FALSE : Failed
 //------------------------------------------------------------------------------ 
 GPIOUTILITYDLL_API int GPIODLL_FreeControlModule(int nModule);
