Or you could change the code of course. The switches will not do any harm if mounted

 

I just checked my old 16F88 single chip Charlieplexed Clock/Calendar/Timer project which was written in BoostC and it only uses 711 words of program memory

Nice and small project. Your crystal is to big to be clock crytsal. Did you use timer 1 , and the compare module approach? And what was your timer tick interrupt rate?

 

board rebuild and ready,
Works ok, have study it a lot, have change the text and make i run backwards in days.

The crystal is 16-MHz (what I had on hand) and I'm using 1-msec (1-kHz) TMR2 interrupts to drive the display and the RTC code. I've attached the source if anyone would like to take a peek.

Good to hear. Any questions. The setup is a framework for a clock. It has all the main components.

 

some question abouth C , i am use to VB.net. in windowsprogramming
but i think i will figure it out ,. }}}} and //

and need the r1 in my setup, but fix it tomorrow, not that big deal

 

Got my setup fixed and all works well.
Changed some code..

void lcd_format_and_send(void)
{          blink=!blink;
           LED=blink; 
           if (blink) lcd_puts("Next LED will be off");
            else lcd_puts("Next LED will be on ");
   lcd_goto(0x40); // Select second line
             //lcd_puts("day of week ");
            //lcd_putch(week_day+48);
            lcd_puts(day_of_week_names[week_day]);
            lcd_goto(0x00);
}
void skriv(void)
{  week_day++;
            if (week_day==7) week_day=0;
            lcd_format_and_send();//send time to LCD
  
}
void main (void) 
 { setup();
      GIE=1;
   TMR1ON=1;
       while (1)
        {
           if (timer_tick)
    { 
skriv();
 timer_tick=0; 
}  // end if (timer_tick) Memo to my self put all this in sub function
 } //end while endless loop
 }//End main

take some time to get it working, cause the R1 i have mounted wrong, and it did not work,. but now all is okay,
Wondering how to make the clock, do i need a "counter" that counts 60 tick to get the minutes, cause i do not need the second

 

You will also generate a timer_tick every second. So yes you have to count up to 60 seconds in silence before updating the display.

 

143.26 illegal conversion of integer to pointer

if (blink) lcd_puts(minut);

have decrared

volatile int time,minut,sec;

why ?

 

The lcd_puts funtion expect a string as input. Also take a look at section "
3.4 SUPPORTED DATA TYPES AND VARIABLES" in the manual in the "........\HI-TECH Software\PICC\9.83\docs" folder. In micro controllers ram are a scarce commodities. So no need to use a int then the number is in the signed/unsigned number range.

 

Still the same, even after removing the declared int
it should be possible to wite a number on screen.

rebuild again, and now it's okay.

 

next build it write same error, rebuild again and then ok,
The output is no good. some strange signs.

 

You are confusing strings and numbers. In C language, strings are stored in an array of char type along with the null terminating character "\0" at the end. To create a string in C you create an array of chars and set each element in the array to a char value that makes up the string. When sizing the string array you need to add plus one to the actual size of the string to make space for the null terminating character, "\0" So if you want to send the number 59 to the LCD you have to create an array of char containing the ASCII codes 53 and 57 and a '\0" As an example

char sec[3];
sec[0]=53;
sec[1]=57;
sec[2]=0;
lcd_puts(sec);

 

okay, so for all second i need to make an array of 60 elements.
sec(0)=00;
sec(1)=01;
sec(2)=02;
...
...
sec(59)=59;

is that what u mean ?

 

Lol well regarding syntax it is nothing wrong in code something like this

const char * ascii_time[] = {"00","01"........"58","59"};
unsigned char seconds;
lcd_puts(ascii_time[seconds]);

but DoH! do not do that. You can do someting like this

char timestr[3]
void main(void)
{timestr[2]='\0';
.
.
.
utoa(timestr, hours, 10);
lcd_puts(timestr);
lcd_puts(":");
utoa(timestr, minutes, 10);
}

I leave to you to look the utoa function

 

Have found out how to use it.
but another problem has accoured.

void lcd_format_and_send(void)
{ 
lcd_goto(0x08);
utoa(timestr, hour, 10);
if (hour<10)lcd_puts("0");
lcd_puts(timestr);
lcd_puts(":");
utoa(timestr, minut, 10);
if (minut<10)lcd_puts("0");
lcd_puts(timestr);
lcd_goto(0x40); // Select second line
lcd_puts(day_of_week_names[week_day]);
 
}

Second line is allways empty.

 

Can you post the full program?
