I am using ccs compiler and firstly I get #device problem, Solved it then i get undefined identifier problem. How to solve it?
| Code: | // Configuration bits
/* _CPUDIV_OSC1_PLL2_1L, // Divide clock by 2
_FOSC_HS_1H, // Select High Speed (HS) oscillator
_WDT_OFF_2H, // Watchdog Timer off
MCLRE_ON_3H // Master Clear on
*/
#include "18F4550.h"
#device adc=10
#define seg_port LATD
#define seg_unit LATA.F0
#define seg_decade LATA.F1
#define seg_hundred LATA.F2
#define seg_thousand LATA.F3
unsigned int i=0,j=0,k=0;
void main(void)
{
unsigned int value[10]={0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90};
unsigned int count,num0,num1,num2,num3,num4;
TRISA=0; // Configure PortA as output port
LATA=0;
TRISD=0; // Configure PortD as output port
LATD=0;
for(count=0;count<9999;count++) // Counter from 0 to 9999
{
num0=count;
num1=num0%10; // Extract the value of unit digit
num0=num0-num1;
num0=num0/10;
num2=num0%10; // Extract the value of decade digit
num0=num0-num2;
num0=num0/10;
num3=num0%10; // Extract the value of hundred digit
num0=num0-num3;
num0=num0/10;
num4=num0%10; // Extract the value of thousand digit
num0=num0-num4;
num0=num0/10;
for(i=0;i<10;i++) // Delay= ((5msx4)x10) = 200ms between two consecutive counts
{
seg_unit=1;seg_decade=0;seg_hundred=0;seg_thousand=0; // Display unit digit
seg_port=value[num1];
Delay_ms(5);
seg_unit=0;seg_decade=1;seg_hundred=0;seg_thousand=0; // Display decade digit
seg_port=value[num2];
Delay_ms(5);
seg_unit=0;seg_decade=0;seg_hundred=1;seg_thousand=0; // Display hundred digit
seg_port=value[num3];
Delay_ms(5);
seg_unit=0;seg_decade=0;seg_hundred=0;seg_thousand=1 // Display thousand digit
seg_port=value[num4];
Delay_ms(5);
}
}
}

Start at the beginning. The original code had fuses set. You need to duplicate these:
| Code: |
/* _CPUDIV_OSC1_PLL2_1L, // Divide clock by 2
_FOSC_HS_1H, // Select High Speed (HS) oscillator
_WDT_OFF_2H, // Watchdog Timer off
MCLRE_ON_3H // Master Clear on
*/
#include "18F4550.h"
#fuses HS_PLL //HS oscillator with PLL enabled
#fuses NOWDTÂ //Watchdog off
#fuses MCLR //enable MCLR
#fuses CPUDIV1 //CPU /1 from clock
#fuses PLL2 //PLL fed off OSC/2
//At this point CCS _[u]requires[/u]_ a clock statement. You don't tell us
//your crystal, but guessing from the settings you have an 8MHz crystal
//and are running the CPU at 48Mhz
#USE DELAY(clock=48MHz, USB_FULL)
|
Then your second problem is trying to talk to the port latch registers and tris registers. CCS does not 'know' these names. You can define them, but easier to change the code to use the CCS commands:
| Code: |
//TRISA=0; // Configure PortA as output port
//LATA=0;
//TRISD=0; // Configure PortD as output port
//LATD=0;
output_a(0); //sets port a as output, and puts 0 into the latch
output_d(0); //same for port d
|
Similarly where you #define seg_decade for example, this needs to just have the pin name. So:
#define seg_decade PIN_F1
and when you want to set this to zero:
output_low(seg_decade);
Just about every line will need a change like this. |

I done the correction but still have 4 more error [undefined identifierPIN_D].
| Code: |
// Configuration bits
/* _CPUDIV_OSC1_PLL2_1L, // Divide clock by 2
_FOSC_HS_1H, // Select High Speed (HS) oscillator
_WDT_OFF_2H, // Watchdog Timer off

*/
#include <18f452.h>
#include <string.h>
#USE DELAY (CLOCK=4000000)
#FUSES XT, NOWDT, NOPROTECT, DEBUG
#fuses NOWDT //Watchdog off
#define seg_port PIN_D
#define seg_unit PIN_A0
#define seg_decade PIN_A1
#define seg_hundred PIN_A2
#define seg_thousand PIN_A3
#USE DELAY(clock=48MHz, USB_FULL)
unsigned int i=0,j=0,k=0;
void main(void)
{
unsigned int value[10]={0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90};
unsigned int count,num0,num1,num2,num3,num4;
output_a(0); //sets port a as output, and puts 0 into the latch
output_d(0);
start:if(input(PIN_C0)){ //PIN CO to start program

num0=num0/10;
for(i=0;i<10;i++) // Delay= ((5msx4)x10) = 200ms between two consecutive counts
{

hmm..
#define seg_port PIN_D
#define seg_unit PIN_A0
PIN_D is 'not defined', means the compiler has no idea what it is.
I'll assume you ment to type PIN_D0 or PIN_D1 and 'lost' the number after the 'D'.
also
this
goto start;}
a LOT of hard core C programmers will say this is 'wrong', though perfectly acceptable and runs fine.
the 'goto' is not liked by most C guys.
The accepted method is to use the
do...
..
...
..
while()...
structure.
The irony to me is that BOTH methods result in a machine code GOTO instruction !

Yes.
In this case.
The reason it is deprecated, is that using the goto makes it possible to jump out of or into a section of code and leave the stack imbalanced. It's a way of potentially shooting yourself in the foot, so 'why use it'. There are a few occasions where it is the best solution, and it should only really be used for these.... |

hmm, hadn't thought about the stack stuff....
wonder if the compiler could be made smarter to clean up the stack when a goto was used?
I know the MS BASIC interpreter for the TRS80s did
