Problems with DLL call to relayboard

[KaVaD 0]

I am a newbie to Autoit and need help with dll calls to a relayboard to switch on and off some relays.

the dll's internal look like this:

// masdll.h

// Header file for the Control Master DLL

///////////////////////////////////////////////

// General Defs

#define MAXBOARDS 30 // maximum number of boards that can be connected to the system

// Board type defs

#define BOARD_MASTER 0 // non isolated master controller

#define BOARD_ISOMASTER 1 // isolated master controller

#define BOARD_DIGITAL_IOSLAVE 2 // digital I/O Slave

#define BOARD_ANALOGUE_IOSLAVE 3 // analogue I/O slave

#define BOARD_RELAY_SLAVE 4 // relay slave

#define BOARD_MOTOR_SLAVE 5 // motor slave

#define NO_BOARD_DETECTED 123 // no board detected at the specified board number

// error defs

#define SUCCESS 0 // no error

#define ERR_REQUEST_FAILED -1 // non specific general failure to process command

#define ERR_INVBOARDNUMBER -2 // invalid board number specified as parameter

#define ERR_NOMASTERFOUND -3 // no master controller found

#define ERR_USB_MESSAGING_ERROR -4 // message received from USB was not as expected (length or header byte)

#define ERR_CHECKSUM -5 // checksum error in data received from slave

#define ERR_WRONG_BOARD_TYPE -6 // wrong command for the board type (eg CM_RELAY_Update used with board number of a Motor Slave)

// sub command defs

#define MOTOR_STOP 1 // stop command used within Direction command

#define MOTOR_FORWARD 2 // forward command used within Direction command

#define MOTOR_REVERSE 3 // reverse command used within Direction command

// DLL Function type definitions

typedef int (*Type_Mas_Initialise)();

typedef int (*Type_Mas_SendMessage8)(int board, int command, int *message, int *answer);

typedef int (*Type_CM_Initialise)();

typedef int (*Type_CM_GetBoardType)(int BoardNumber);

typedef int (*Type_CM_DIO_Update)(int BoardNumber, int Outputs, int *Inputs);

typedef int (*Type_CM_DIO_GetStatus)(int BoardNumber, int *Outputs);

typedef int (*Type_CM_RELAY_Update)(int BoardNumber, int Outputs, int *Inputs);

typedef int (*Type_CM_RELAY_GetStatus)(int BoardNumber, int *Outputs);

typedef int (*Type_CM_ANIO_Update1to4)(int BoardNumber, int Outputs, int *Inputs, int Sensitivity);

typedef int (*Type_CM_ANIO_Update5to8)(int BoardNumber, int Outputs, int *Inputs, int Sensitivity);

typedef int (*Type_CM_ANIO_GetStatus)(int BoardNumber, int *Outputs, int *Sensitivity);

typedef int (*Type_CM_Motor_M1Speed)(int BoardNumber, int Speed, int *Inputs);

typedef int (*Type_CM_Motor_M1Direction)(int BoardNumber, int Direction, int *Inputs);

typedef int (*Type_CM_Motor_M2Speed)(int BoardNumber, int Speed, int *Inputs);

typedef int (*Type_CM_Motor_M2Direction)(int BoardNumber, int Direction, int *Inputs);

typedef int (*Type_CM_Motor_ReadInputs)(int BoardNumber, int *Inputs);

typedef int (*Type_CM_Motor_GetStatus)(int BoardNumber, int *M1Speed, int *M1Dir, int *M2Speed, int *M2Dir, int *Inputs);

This is what I have done so far with no success.

The boardnumber has address 2 via a dil switch on the printboard.

The outputs value 85 is the decimal value of binary value 01010101 which will turn on relays 1,3,5 and 7 (reading from right to left)

Global $Boardnumber

Global $Outputs

Global $Inputs

Global $RelayUpd

Dim $Error

$Error = CM_Initalise()

If $Error = 0 Then

test()

$Boardnumber = 2

$Outputs = 85

$Inputs = 0

CM_RELAY_Update($Boardnumber,$Outputs,$Inputs)

MsgBox(0,"RelayUpdat",$RelayUpd)

Else

EndIf

Func CM_Initalise()

$Init= DllCall ("mas.dll","int","Initialise")

if @error Then Return 0

Return $Init

EndFunc

Func CM_RELAY_Update($Boardnumber,$Outputs,$Inputs)

$RelUpd = DllCall ("mas.dll","int","Boardnumber","int","Outputs","int","Inputs")

if @error Then Return 0

Return $RelUpd[0]

EndFunc

Can someone help me with the calls ?

maybe a working example?

thanks in advance

The header you posted is like a bunch of DllStructCreate() tags, not the functions themselves.

Shouldn't that cal for example be to "CM_Initialise"?

DllCall() always returns an array. The returned int value would be in $Init[0].

DllCall() always returns an array. The returned int value would be in $Init[0].

In the Manual the Function Name is: CM_Initialise

Syntax for 'C/C++' is : int CM_Initalise()

Syntax for 'Visual Basic' : CM_Initialise () As Integer

Function Name: CM_RELAY_Update

Syntax for 'C/C++' : int CM_RELAY_Update (int BoardNumber,int Outputs, int Inputs)

Syntax for 'Visual Basic' :CM_RELAY_Update (ByVal BoardNumber AS Integer,

ByVal Outputs As Integer,

ByVal Inputs As Integer ) As Integer

I have no idea how to translate it to Autoit

Anyone who can give me some starting help, with an example code?

Those aren't functions or structures. Those are just definitions for callbacks actually.

What C++ you posted alone wouldn't even work in C++.

The manual of the Control board and the Relay board is at this url.

on page 37 the programmers guide start.

In the manual a VB dllcall has this syntax :

Declare Function CM_DIO_Update Lib "mas.dll" (ByVal BoardNumber As Integer, ByVal Outputs As Integer, ByRef Inputs As Integer) As Integer

Dim BoardNumber As Integer

Dim Inputs As Integer

Dim Outputs As Integer

BoardNumber = 2

Outputs = 85 „ outputs 1,3,5 and 7 On, 2,4,6 and 8 off

„ Update the board (i.e. send the new outputs and read back the current inputs

CM_DIO_Update( BoardNumber, Outputs, Inputs )

„ After the above call, the variable inputs would hold the current pattern of inputs appearing at the board

Is this how you will call it from Autoit??

Global $Boardnumber

Global $Outputs

Global $Inputs

Global $DIO_upd

$Boardnumber = 2

$Outputs = 85

$Inputs = 0

CM_DIO_Update($Boardnumber,$Outputs,$Inputs)

Func CM_DIO_Update($Boardnumber,$Outputs,$Inputs)

$DIO_upd = DllCall ("mas.dll","int","Boardnumber","int","Outputs","int","Inputs")

if @error Then Return 0

Return $DIO_upd

EndFunc

You might try it like this:

#include <Array.au3>

; Declare Function CM_DIO_Update Lib "mas.dll" (
;       ByVal BoardNumber As Integer, _
;       ByVal Outputs As Integer, _
;       ByRef Inputs As Integer) As Integer

Global $iBoardNum = 2
Global $iOutputs = 85
Global $iInputs = 0

Global $aRET = DllCall("mas.dll", "int", "CM_DIO_Update", "int", $iBoardNum, "int", $iOutputs, "int*", $iInputs)

; [0] = Return value (usually 0=success, depends on function)
; [1] = Repeat back of first param
; [2] = Repeat back of second param
; [3] = Repeat back of third param, which may have been changed by the function (because it was passed ByRef "int*")
_ArrayDisplay($aRET, "$aRET")
