Yes.

How easy it is, depends on the PIC.
Simplest way, use a PIC that supports two different timers for PWM.
Program the timers to give the required 1000Hz rate.
Program the two PWM's, onto the ...

Hi,

you can generate two square waves with a PIC 1000 Hz out of phase with each other in advance or delay of 90 degrees?

I think it's a bad idea. What if your program is stuck in a loop for some
reason ? The timer interrupt would keep restarting the Watchdog Timer
and you would never get a Watchdog reset. Your co ...

Hi

can also do so #use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, restart_wdt, ERRORS)

Thank you for the answers, but what do you think of using a timer interrupt to recharge the watch dog?

Hi!

if i want to use the watch-dog functions blockers in type "void get_string (char * s, unsigned int8 max)" contained in "input.c" i have to change the function or there are o ...

Hi!

Post your PIC.

with this work:

#include <16F877a.h>
#include <apricancello_gsm.h>
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRO ...

hi!

See the clear_usart_receiver() function in this post:

if i use the program crashes, i think it is a problem with the USART:

Hi!

You can reset RCREG directly? or the system is this:

while(kbhit())
{
printf("the character is:%c", getc());
}

Hi!

thanks

without you i do not know how to do :-)

Hi!

I am using a PIC16F877A, as possible checking RCIF? as you are reading RCREG?

Hi!
+CLIP: "+3933812345678",145,"",128,"Giacomo" //is in the phone book

the string is wrong with the modem gm862 puts an end 0

Hi!

Thanks for the information, I believe that in the future I will use the ISR.

Hi!

Working!!!

I wanted to add: the compiler shows a message Warning: variable never used: rs232_errors

Thanks

Hi!

I'm using the development board CCS with 16f877A i uploaded example EX_STR.C

working normally, but when i pressed the enter key on the keyboard without releasing, the program on the PIC (EX_ ...

Thanks works perfectly
