74HC595!!!!!!!PROGRAM
PostPosted: Fri Nov 06, 2009 12:46 pm     Reply with quote
hi...In my project, I am using the pic to control my 22 x 12 RGB led board to display the words and some animation.

I have totally no idea how to control the 74HC595. And I also don't no how to use 1 bit to control 8 bits output...Hope any know the idea or EXAMPLE of simple program can show.

Beside that, I am not sure how to transfer the serial input of first 595 to the second 595. Hope anyone know it, can share the idea with me. THANKS

Code:

//------ Do 74HC595 serial chip --------------
//MSB > xxxx xxxx     xxxx xxxx < LSB
void Do_Serial_Chip(int8 Fuera1,int8 Fuera2)
   {
   int8 i;
   int16 ajuera;
   
   ajuera = Fuera1;
   ajuera = ajuera<<8;
   ajuera = ajuera | Fuera2;
   
   // Output to serial line
   for(i=0; i<16; i++)
      {
      if(ajuera & 0x8000)
         {Serial = 1;}
      else
         {Serial = 0;}
         
      ajuera = ajuera<<1;
      
      SLOK = 0;     //Shift data
      SLOK = 1;
      }

   RCK = 0;         //Output on pins
   RCK = 1;
   }
