Where does EasyCAT come from?

You haven't wrapped the library correctly.

jinyistudio · Feb 20, 2019

attached file is my first wrapped library. I need help

Siam · Feb 20, 2019

#include "B4RDefines.h"
namespace B4R {
void B4REasyCAT::Initialize() {
hat = new (beEasyCAT) EasyCAT();
hat->Init();
}

void B4REasyCAT::Initialize1(unsigned char SPI_CHIP_SELECT) {
hat = new (beEasyCAT) EasyCAT(SPI_CHIP_SELECT);
hat->Init();
}

void B4REasyCAT::Initialize2(SyncMode Sync) {
hat = new (beEasyCAT) EasyCAT(Sync);
hat->Init();
}

void B4REasyCAT::Initialize3(unsigned char SPI_CHIP_SELECT, SyncMode Sync) {
hat = new (beEasyCAT) EasyCAT(SPI_CHIP_SELECT,Sync);
hat->Init();
}
}

the green one is the right place the red ones are wrong (redefines)
have a look to the other libs on github ... this helped me a lot

Hi
The original program(EasyCAT.h) has 4 constructor. So I build 4 Initialize function. Is this wrong?

B4X:

    EasyCAT();                              // default constructor
    EasyCAT(unsigned char SPI_CHIP_SELECT);
    EasyCAT(SyncMode Sync);            
    EasyCAT(unsigned char SPI_CHIP_SELECT, SyncMode Sync);

jinyistudio · Feb 21, 2019

Hi
It seems that there is no problem with following.

B4X:

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
End Sub

Private Sub AppStart
    RunNative("Initialize", Null)
    Log("AppStart")
End Sub

#if C
    #include <EasyCAT.h>
    EasyCAT hat;

    void Initialize (B4R::Object* o) {
        hat.Init();
    }
#End if

Siam · Feb 21, 2019

hi,

so far i see you need only one constructor

EasyCAT(unsigned char SPI_CHIP_SELECT);
EasyCAT(SyncMode Sync);
EasyCAT(unsigned char SPI_CHIP_SELECT, SyncMode Sync);

the first line inits easycat only with the cs

the next line inits easycat only with the sync mode

and the last line inits easycat with sync mode and cs

so you have to check in the init routine if SPI_CHIP_SELECT or / and SyncMode Sync is set
and then you can call the right constructor.

Hi

I try to remove any function as following. I found that the same problem occurs when I include "EasyCAT.h".

rEasyCAT.h

B4X:

#pragma once
#include "B4RDefines.h"
#include "EasyCAT.h"
//~version: 1.1
namespace B4R {
    //~shortname: EasyCAT
    class B4REasyCAT {
        private:   
              
        public:
            void Initialize();           
            void CycleTask();
    };   
}

rEasyCAT.cpp

B4X:

#include "B4RDefines.h"
namespace B4R {   
    void B4REasyCAT::Initialize() {
      

    }   
}

Please change the tread title to something more meaninfull

Siam · Feb 21, 2019

ok now i understand the problem

This part in The library is the problem:

B4X:

//--------------------------------------------------------------------------------
// This is the code that usually is in the .cpp file.
// This seems to be the only way to allow the library
// configuration through "#defines" in the ino. file 
//-------------------------------------------------------------------------------- 
 
    
//---- constructors --------------------------------------------------------------------------------

EasyCAT::EasyCAT()                              //------- default constructor ----------------------
{                                               //
  Sync_ = ASYNC;                                // if no synchronization mode is declared
                                                // ASYNC is the default
                                                //
  SCS = 9;                                      // if no chip select is declared
  digitalWrite (SCS, HIGH);                     // pin 9 is the default
}                                               //


EasyCAT::EasyCAT(unsigned char SPI_CHIP_SELECT) //------- SPI_CHIP_SELECT options -----------------
                                                //
                                                // we can choose between:
                                                // 8, 9, 10, A5, 6, 7
{                                               //                                       
  SCS = SPI_CHIP_SELECT;                        //  initialize chip select 
  digitalWrite (SCS, HIGH);                     //     
}
 

EasyCAT::EasyCAT(SyncMode Sync)                 //-------Synchronization options ----------------------

for now i have no solution to fix this issue maybee someone with more C knowledge can help you

B4R Question Where is the error ?
