Trouble in RS232 stream. v.5.021
PostPosted: Sat Mar 29, 2014 11:27 pm     Reply with quote
Trouble in RS232 stream.
In version 4.124 works. OK!!
In version 5.0 - 021, does not work.
I ask for help.
Obs: translated into English.

Code:

#include <18LF24J11.h>

#FUSES NOWDT
#FUSES INTRC_IO
#FUSES NOPROTECT
#FUSES RTCOSC_T1   

#use delay(clock=8000000)  // funcionou com 4Mhz
#use rs232(uart1,baud=4800,parity=N,bits=8,stream=buffer)


//char buffer[160];
rtc_time_t tWriteTime;
rtc_time_t tAlarmTime;

#int_RTC
void RTC_isr(void)
{
 rtc_alarm_read(&tAlarmTime);
//sprintf(buffer,"%02u:%02u:%02u",tAlarmTime.tm_hour,tAlarmTime.tm_min,tAlarmTime.tm_sec);  // not working
sprintf(buffer,"\n\r%02u/%02u/20%02u %02u:%02u:%02u",tAlarmTime.tm_mon,tAlarmTime.tm_mday,tAlarmTime.tm_year,tAlarmTime.tm_hour,tAlarmTime.tm_min,tAlarmTime.tm_sec); // not working
printf("%s\n\r",buffer);

}

void main()
{

 delay_ms(1000);

   tWriteTime.tm_year = 9;
   tWriteTime.tm_mon  = 11;
   tWriteTime.tm_mday = 24;
   tWriteTime.tm_wday = 2;
   tWriteTime.tm_hour = 16;
   tWriteTime.tm_min  = 1;
   tWriteTime.tm_sec  = 0;

   tAlarmTime.tm_year = 9;
   tAlarmTime.tm_mon  = 11;
   tAlarmTime.tm_mday = 24;
   tAlarmTime.tm_wday = 2;
   tAlarmTime.tm_hour = 16;
   tAlarmTime.tm_min  = 1;
   tAlarmTime.tm_sec  = 5;

   setup_rtc(RTC_ENABLE | RTC_OUTPUT_SECONDS, 0x00);
   setup_rtc_alarm(RTC_ALARM_ENABLE, RTC_ALARM_HOUR|RTC_ALARM_MINUTE|RTC_ALARM_SECOND, 10);
   rtc_write(&tWriteTime);
   rtc_alarm_write(&tAlarmTime);
   enable_interrupts(GLOBAL);
   enable_interrupts(int_rtc);
  //
   rtc_read(&tWriteTime);
  sprintf(buffer,"\n\r%02u/%02u/20%02u %02u:%02u:%02u",tWriteTime.tm_mon,tWriteTime.tm_mday,tWriteTime.tm_year,tWriteTime.tm_hour,tWriteTime.tm_min,tWriteTime.tm_sec);
  printf("%s\n\r",buffer);


   while(1)
   {
   }
}

Is your basic complaint that sprintf doesn't work with the 18LF24J11 with
vs. 5.021 ?

It worked for me. I cleaned up your program. I did not name the
stream as "buffer" and then try to send sprintf output to the stream.
That's not supported. It's not in the CCS manual.

I compiled the following test program with vs. 5.021, then I ran it in
MPLAB simulator with the RS232 output sent to the Output Window.
It displays this:

It's working.

Here is the test program:
Code:

#include <18LF24J11.h>
#FUSES NOWDT
#FUSES INTRC_IO
#FUSES NOPROTECT
#FUSES RTCOSC_T1   

#use delay(clock=8000000)   
#use rs232(uart1,baud=4800,parity=N,bits=8)

char buffer[160];
rtc_time_t tWriteTime;
rtc_time_t tAlarmTime;


void main()
{
   tWriteTime.tm_year = 9;
   tWriteTime.tm_mon  = 11;
   tWriteTime.tm_mday = 24;
   tWriteTime.tm_wday = 2;
   tWriteTime.tm_hour = 16;
   tWriteTime.tm_min  = 1;
   tWriteTime.tm_sec  = 0;

   tAlarmTime.tm_year = 9;
   tAlarmTime.tm_mon  = 11;
   tAlarmTime.tm_mday = 24;
   tAlarmTime.tm_wday = 2;
   tAlarmTime.tm_hour = 16;
   tAlarmTime.tm_min  = 1;
   tAlarmTime.tm_sec  = 5;

  sprintf(buffer,"\n\r%02u/%02u/20%02u %02u:%02u:%02u",tWriteTime.tm_mon,tWriteTime.tm_mday,tWriteTime.tm_year,tWriteTime.tm_hour,tWriteTime.tm_min,tWriteTime.tm_sec);
  printf("%s\n\r", buffer);


   while(1)
   {
   }
 
}

I would agree..


S-printf means "STRING" not stream at last I recall.

you use FPRINTF to print to a stream typically.

I'm not using 5.x yet, but the code you supplied already shows a disconnect between what you think you can do with printf in the f- and s- form.


if I were using both for some reason it would go more like this: (not a compilable example)

Code:

#use rs232(uart1,baud=4800,parity=N,bits=8,stream=COM1)

char buffer [160];

sprintf(buffer, "some string with stuff in it\r\n");
fprintf(COM1, buffer);



I probably wouldn't do exactly as shown above since fprintf can take sprintf syntax. If I were to bother using sprintf and then fprintf like that above, it'd be because I was doing something more complex than that.. but you get the idea.

check the PIC-C manual for more.
