Structures for PORTA,B, etc
PostPosted: Fri Jul 30, 2004 10:05 am     Reply with quote

I would like to use a more standard way to access pins more like other compilers which define stuff like code below.

The idea is that using this setup you can:

PORTAbits.RA0=1; //sets pin A0 to high value...

Is their a simple way to map the structures to memory locations using CCS?


extern volatile near unsigned char PORTA;
extern volatile near union {
struct {
unsigned RA0:1;
unsigned RA1:1;
unsigned RA2:1;
unsigned RA3:1;
unsigned RA4:1;
unsigned RA5:1;
unsigned RA6:1;
};
struct {
unsigned AN0:1;
unsigned AN1:1;
unsigned AN2:1;
unsigned AN3:1;
unsigned T0CKI:1;
unsigned AN4:1;
unsigned OSC2:1;
};
struct {
unsigned :2;
unsigned VREFM:1;
unsigned VREFP:1;
unsigned :1;
unsigned LVDIN:1;
unsigned CLKO:1;
};
} PORTAbits;

Easy. Just define your structure:

Code:
struct lcd_pin_def
{
   BOOLEAN unused1;    // C0
   BOOLEAN unused2;    // C1
   BOOLEAN unused3;  // C2
   BOOLEAN unused4;  // C3
   BOOLEAN w_bar;  // C4 Write bar active low
   BOOLEAN r_bar;  // C5 Read bar active low
   BOOLEAN cd;         // C6 Command/Data BAR   1=command 0=data
   BOOLEAN reset_bar;  // C7 Reset active low
   int  data    :  8;  // PortD=Data bus
};
struct lcd_pin_def  LCD;


Then tell the compiler what port register to associate with the struct:

Code:
#byte LCD = 0xf82    // portC address on 18F452


Then use each "pin":
Code:

  LCD.w_bar = 1;      // INITIAL STATES OF CONTROL PINS
  LCD.r_bar = 1;      //
  LCD.cd = 1;         // command


This is an excerpt from some graphical lcd drivers I posted earlier. You'll notice that I mapped the struct to port C, and since the struct is really 16 bits long, it spills over into port D.

All you need to do is look up the address of the port's register in the datasheet of whatever pic you're using. Just search through the memory organization section for "special function registers".

The only thing to be careful of is the io mode. If you use the default standard io mode, the compiler will automatically set each bit as an input or output each time you call it/set it in your code. If you use fast io mode, you have to set each bit as input/output, and keep track of your settings, because the compiler won't touch the tris registers.

Thanks for the information...

I tried that but I don't think CCS supports unions as in the structure I was using...

Edited: Had to remove the unions. CCS doesn't like unnamed structs.

Hey Mark, did you add to that file? Or is it the standard .h file for newer versions? I can't find such an exhaustive .h file anywhere in my 3.191 distribution.

I notice the use of the #locate directive to define a PIC register. I usually use the #byte PIR1=0xF33 way of doing it.

Yeah, I added to it. I don't think you can use #byte on a struct. I may be wrong on this since I have never tried it but I don't think it will work. After getting my code converted back to CCS today, I discovered that they do not support unnamed structs like the C18 so the unions in the header file won't work Sad Not that big of a deal. One of the regs has the wrong address also. I'll post a corrected version tomorrow when I get back to work.
