Trouble in RS232 stream. v.5.021 |

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.
