Re: PortB question

1. Goto C:\DCRABBIT_XX.XX\Utilities, then open IOConfig.exe. 
2  Change your IO On "Parallel Ports Pin Assignments according to your needs.
3  Klik File - Save Library- typo C:\DCRABBIT_XX.XX\LIB\Rabbit4000\mylibrary.lib in "Library File Pathname"
4. Open mylibrary.lib C:\DCRABBIT_XX.XX\LIB\Rabbit4000 used Dynamic C and see this line:

void BoardInit()
{
   // ClockCheck();
   // The following differ from BIOS settings
   WrPortI(PBDDR,&PBDDRShadow,0xFF);     // Port B Input and output Pins
   WrPortI(PCDDR,&PCDDRShadow,0xFF);     // Port C Input and output Pins
   WrPortI(PCFR,&PCFRShadow,0x00);     // Port C Input and output Pins
   WrPortI(SPCR,&SPCRShadow,0x84);     // Port A Input and output Pins
}

5. Open your program from Dynamic C IDE add as follows:

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

#use "rcm57xx.lib"
//#use "mylibrary.lib";  // call mylibrary.lib from here OR paste code direct in code

main()
{
   int i;

   brdInit();  // Press <CTRL H> for view this settings
               // Select brdInit in "C:\DCRABBIT_10.56\LIB\RABBIT4000\RCM5XXX\RCM57XX.LIB" then 
               //   press Ok, you will see the default settings for your board in here
               // Click View Source for edit RCM57xx.LIB you can change the library or directly here but I do not advise it.
               // Change library from mylibrary.lib or direct paste as follows:
   
   // paste your config in here
   WrPortI(PBDDR,&PBDDRShadow,0xFF);     // Port B Input and output Pins
   WrPortI(PCDDR,&PCDDRShadow,0xFF);     // Port C Input and output Pins
   WrPortI(PCFR,&PCFRShadow,0x00);       // Port C Input and output Pins
   WrPortI(SPCR,&SPCRShadow,0x84);       // Port A Input and output Pins

   //WrPortI(SPCR, NULL, 0x84); // Port A as output
   //WrPortI(PBDDR, &PBDDRShadow, 0xff); // Port B as output
   //WrPortI(PBDDR, &PBDDRShadow, 0xff); // Port C as output


   while(1)
   {
      // add your programs in here 

      //WrPortI(PADR,    &PADRShadow,i);
      //WrPortI(PBDR,    &PBDRShadow,i);
      //WrPortI(PCDR,    &PCDRShadow,i++);
   }

}
