| Am I missing something? |

I'm getting the error "Expecting function name ::" at each line that contains a printf() statement. Here is a code snippet:
| Code: |
if(!input(PIN_A0))
{
x=9;
while(!input(PIN_A0) && x)
{
printf(lcd_putc,"Pending\nReset");
lcd_gotoxy(8,2);
printf(lcd_putc,"%d",x--);
delay_ms(1000);
}
if(!x)
{
WRITE_LONG_EEPROM(0, (int32)0);
lcd_putc('\f');
printf(lcd_putc,"Reset\n PWR OFF");
while(1);
}
}
|
If I comment out the printf() lines it compiles without error. I figure I must be missing something here, and perhaps another set of eyes will see it?
Thanks,
Glenn

With no more than you have given us I randomly picked a short section of
test code I had and dropped yours into it. It compiled it under 5.051 with no
problems. It may be something further upstream.
What chip?
What compiler version?

lcd_putc needs to go somewhere
lcd_putc(char buffer)
{
// put charter somewhere
}
if you have something like this, you may be missing the prototype for this funtion |

I have lcd_putc() defined in gh_lcd.c. It's just a modification of the original CCS file lcd.c that I've been using for years.
As a test, I built this little program:
| Code: |
/*
* File: newmain.c
* Author: glenn
*
* Created on November 21, 2015, 12:21 PM
*/
#include <16F1823.h>
#device WRITE_EEPROM = NOINT
#fuses PUT,NOWDT,INTRC_IO,NOMCLR,NOCLKOUT,NOIESO,NOLVP,NOPROTECT,NODEBUG
#USE STANDARD_IO(a)
#USE STANDARD_IO(c)
#use delay(clock=8M)
#include <stdio.h>
#include <stdlib.h>
#include <lcd.c>
int main(void)
{
printf(lcd_putc,"Hello") ;
while(1);
}
|
And it generated these errors:
*** Error 28 "/opt/picc/drivers/lcd.c" Line 163(4,5): Expecting an identifier Bad SFR name
*** Error 12 "/opt/picc/drivers/lcd.c" Line 163(5,9): Undefined identifier
*** Error 48 "/opt/picc/drivers/lcd.c" Line 163(10,16): Expecting a (
*** Error 28 "/opt/picc/drivers/lcd.c" Line 164(4,5): Expecting an identifier Bad SFR name

*** Error 43 "/opt/picc/drivers/lcd.c" Line 164(34,38): Expecting a declaration
9 Errors, 0 Warnings.
Build Failed.
So something is amiss. Can you compile this little program?

You are missing some defines that must be before lcd.c
Look at the comments in the lcd.c file for info.
| Quote: | //// To use port access, #define LCD_DATA_PORT to the SFR location of ////
//// of the GPIO port that holds the interface, -AND- edit LCD_PIN_MAP ////
//// of this file to configure the pin order. If you are using a ////
//// baseline PIC (PCB), then LCD_OUTPUT_MAP and LCD_INPUT_MAP also must ////
//// be defined. |

Ah, yes. That info is in my header file. I forgot to put it in my simple program.
I added this, and it still fails, same errors. I don't understand why it used to compile OK, but now gives this weird error.

Duh! Thanks.
OK, That compiles fine. So I'm back to my original problem.

I would first go back and add the defines prior to your gh_lcd.c include...

Strike that. I just reopened my original file, and it compiled error free.
So that was a time sink I guess.
Thank you for looking, I appreciate it.
