I want to interface humidity sensor to PIC 16F877A. could anyone please suggest me  which sensor is best w.r.to price and minimal components

Hi Amrit,

 

     Can I have your mail Id ?

[srikanth]

 

 

 Thanx Amrith for the reply and i will try it tomorrow.

     

              Can you pls tell me how the crystal frequency like 4Mhz or 20 Mhz  influences my delay which i gave in the program.

Because when iam executing ATDXXXXXX;  command, its nt getting successful sometimes but is working fine with Hyperterminal all the time and also iam started working on gprs for data transfer from remote to home pc, pls give me some guidance. thanx  …

Thnx  Amrith ,

 

 

       Now im tryin to make a  voice call…

Amrith 

 

            thanx for your replies..  If the network unable to delivery the message  in time , then no use of my project. it can b happend due to jamming in network.  So is it possible for my microcontroller to see the delivary report and send again??

  Hi Amrit,

 

 

              I successfully sent SMS using SIM 300 modem wit PIC microcontroller.  Is it possible to send SMS to multiple numbers at a time??

Hi,

 

     Is it possible to send SMS to multiple numbers at a time through SIM 300?? I can able to send SMS to a single number.

when i loaded my code, when i enterd any character through keybord the output is not in proper format , its giving like this  —

                                                                                                                                                                                           — .

                                                                                                                                                                                           —

 

my code is : #include “C:Program FilesPICCProjectsNew FolderpradUART.h”
#include <stdio.h>
//#include <18f452.h>
#use rs232(baud=9600,xmit=pin_c6,rcv=pin_c7)
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=2000000)

void main(void)
{

unsigned char k;

   setup_adc_ports(NO_ANALOGS);
   setup_adc(ADC_OFF);
   setup_psp(PSP_DISABLED);
   setup_spi(FALSE);
   setup_wdt(WDT_OFF);
   setup_timer_0(RTCC_INTERNAL);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_oscillator(False);

  while(1)
  {
 k= fgetc();
 fputs(k);
 printf(“41H”);

   // TODO: USER CODE!!
};
}

   I did small projects  with LEDs, and ADC…

 

    But for LCD i got many doubts.. specially using with predefined functions..

   Amrit ,

 

           I mean CCS C compiler programming for PIC microcontrollers..

Hi Amrith,

 

     Could you tell me the best way to learn CCS coding ..
