Compare Data

[Pesticida]

Hi,

I´need a Solution for my Firmware,I must to compare Received Data,but the Problem is that the lenght of the strings are not always the same.

For Example i send $WP+CALL=12345... and I should receive this $OK:CALL or $ERR:CALL when I use this $WP+GSMINFO=1234 i should receive $MSG:GSMINFO="xxx",27,0,0.

All the answers have this first character "$" and I want to put the Answer on my LCD.

Receive:
Dummy[Input_Byte_Count] = RCREG ' Clear USART Flag by reading USART data
If Dummy[0] = 36 then ' Character $
High LCD_Light
Lcdout $fe, 1 ' Clear screen
If Dummy[Input_Byte_Count] = 10 then 'Line Feed
Pause 5
Lcdout $fe,$80,str Dummy\Input_Byte_Count+1
Pause 5
Input_Byte_Count = 0
else
Input_Byte_Count = Input_Byte_Count + 1
endif
else
Dummy[0] = $00
endif
Resume

Is this a good way to do this ?

Thanks for any answer

Regards Pesti

Pesticida, Is there some EOL character sent at the "End of Line"? You can use this character (ie.CR/LF) as a terminator for the input string to your LCD display...

Hi,

Yes Feed New Line.

I think that my Problem is that if I use Dummy=RCREG with RCIF Interrupt I become a overflow.

I must to try with Hserin.

And again, just like the last bunch of posts, you answer awaits you in the PBP manual...It's all about terminating the SERIN2/HSERIN input with an optional character...
It's in the book if you just take the time to look.
I understand what you're trying to do and as soon as you read the book, really read the book, the answer will show up...right in front of you...especially since you said that each line is ended with some sort of optional character, in your case, a line feed character.

Sorry but i dont have exactly explain my Problem,I know how this work but my problem is how to make a routine that check for example if I receive this $OK:CALL, then is the call ok and so on.

How to verify Long strings?

I send this $WP+CALL=12345... and then from gsm module receive $OK:CALL.
