How much input oscillation is required in the circuit diagram when 9600 baud rate is set in the code?
Because i cnt get an output from circuit after making connections. So i have a feeling my oscillation is not enough.
So please help with the right amount of oscillation required so that i can...
The problem is there is no output at the seiral ports. Especially RC6 for transmission. I was hoping i would get some output voltage at that pin because im pushing out some character with the function putst() but there is non.
Is there anything else i have left out in the code. please help and...
thanks for your reply i did that change and used putst() function. When I simulate this code using PIC16F877, MAX232, and Virtual Terminal in place of modem, it reflects that data is being trnsmitted but when I perfom it pratically it fails.
I was wondering if there is anything I left out in...
Can you please help find the mistake on this code because it cn't send SMS after programming it into PIC16f877
please help me. Submission is due tomorrow
#include <pic.h>
#include <conio.h>
#include <stdio.h>
//#include "always.h"

I am trying to program PIC16f877 using ICD 2 and i get this error; unable to enter debug mode
Can anyone help me to get past this problem? really need to get past this and progress to other parts. plizz help
Re: Please comment on my project, GSM security sytem using S
I want to sent the following AT commands to the modem via the transmission(Tx) port of the PIC16F877 using C code. AT+CPIN = 1671, AT+CMGF=0
Here is the code i have been trying to assemble. Can you help me to correct this code. I...
Re: Please comment on my project, GSM security sytem using S
I would like to congradulate you because i am really struggling with the the similar project, but i only have to sent a text message in case thereis an intrusion in remote place. I have to use PIC16F877 to send AT commands to the GSM...
Well i can't use hyperterminal because i have to write an sms to the GSM modem which is interfaced with the PIC16F877.
that is why i am seeking helping with the C code of programming AT commands just to get started. So i am in desparate need of code. Plizz i need your help
Up to this moment i have studied most of the AT commands, commands like AT+CPIN = " pin#", AT+CMGF = 0 for setting PDU mode. I have also studied some basics of C programming.
My main problem is to write a code to sent these AT commands via the RS323 cable. can anyone help plizz, i realy need...
