| TC35I Receive question---use the txt message control LED |

hello guys
I use the TC35I receive a txt message to control LED.
But when my code use the printf "AT", the buffer can't receive the "OK". Please help me check it, and where am I wrong in my code?
My code as follow:
| Code: |
#include <18f452.h>
#include <string.h>
#fuses HS,NOWDT,PUT,NOPROTECT
#use delay (clock = 20000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,parity=N,bits=8)
#zero_ram
#define PORTA 0xF80
#define PORTB 0xF81
#define PORTC 0xF82
#define PORTD 0XF83
#bit col8=PORTC.0 //Matrix LED common
#bit LED1=PORTD.0 //
#bit LED2=PORTD.1 //
#bit LED3=PORTD.2 //
#bit LED4=PORTD.3 //
#bit IGT =PORTD.4 //
#bit LED5=PORTD.5 //
#bit LED6=PORTD.6 //
#bit LED7=PORTD.7 //
#define Buf_Max 200 //buffer length200
#define NOT_FOUND (NULL)
unsigned char num[]="OK";
unsigned char i = 0; //
unsigned char Rec_Buf[Buf_Max]; //

unsigned char Command4[]="unled4";
void CLR_Buf(void); //clear the buffer
int1 Hand(unsigned char *a);

I don't think this method of array initialization works in CCS:
| Quote: |
unsigned char *num="OK";
unsigned char i = 0; //
unsigned char Rec_Buf[Buf_Max]; //
unsigned char *N_MS="+CMTI";
unsigned char *Command1="led3";
unsigned char *Command2="unled3";
unsigned char *Command3="led4";
unsigned char *Command4="unled4";
|
Change all the array declarations to a more traditional K&R method, like this:
| Code: |
unsigned char num[]="OK";
|
CCS follows K&R (mostly), and that's how the K&R book says to initialize
an array. (Page 83 of K&R 1st Edition, 1978). |

Thank you for your advice!
I modified my code
| Code: |
unsigned char num[]="OK";
unsigned char i = 0;
unsigned char Rec_Buf[Buf_Max];
unsigned char N_MS[]="+CMTI";
unsigned char Command1[]="led3";
unsigned char Command2[]="unled3";
unsigned char Command3[]="led4";
unsigned char Command4[]="unled4";
|
BUt it doesn't running normal, the buffer can't receive the"OK",and the LED1 light. |

hi,
check this out:
http://www.ccsinfo.com/forum/viewtopic.php?t=42527
it does what you want... for 4 LEDs.
used a different phone... you might need to modify it a bit to work with yours.
BUT, first things first... you must know 100% that your COM between pic and Cell is working...
i recommend you make a spliced cable where you can see the serial from the phone on your PC as well...
that way you know if your pic is actually making the phone respond.
next up, make a simple program that sends an AT command to the phone and checks for reception of "OK"...
once you got that.... its all down hill... its just a matter of reading the AT command list for your phone and sending the right commands from the PIC....

from a quick look...
Add 'errors' to the rs232(....) options ! Otherwise the UART will stop after 2 bytes from the phone. |

Instead of acting helpless, learn how to trouble-shoot a program.
You have a problem. The program doesn't find "OK" in the modem
response. You are checking for "OK" with the strstr() function.
It requires two strings.
How do you know for a fact what is in those two strings ?
You don't.
So, put in some diagnostic printf statements at the start of your Hand()
function so you can see the contents of the two arrays. Add the lines
shown in bold below:
| Quote: |
int1 Hand(unsigned char *a)
{
printf("Num = %s \r\n", a);
printf("Rec_Buf = %s \r\n", Rec_Buf);
printf("\n\r");
if(strstr(Rec_Buf,a)!=NULL)
return (1);
else
return (0);
}
|
The Num array should contain "OK", and the Rec_Buf array should also
(you hope) contain "OK". If one or both of them do not have "OK", then
you need to investigate and do more trouble-shooting of the code for that
array, and look in other parts of the program for the problem.
What I want you to do is to stop acting helpless, and to start trouble-
shooting your own code. |

I found the wrong that I forgot set the C7 input mode ,the code is setted as follow:
My code is OK,when I modified this code! |
