PLIZ CHECK MY SCHEMATIC,pic16f84->max232->gsm phone

[keithdoxey]

The defines you have that start with "HSER" are for a harware serial port which the F84 doesnt have therefore the compiler will not be happy with you trying to define a non existant value.

[Ioannis]

Please READ the manual about the Syntax of the Commands.

You do not define the port pin, the baud rate. No wait for Serin (only for Serin2). No square brackets for the variables. Only in Serin2.

Same for the Serout/Serout2.

And as keithdoxey noted, no DEFINEs as these are for he Hserin/Hserout.

I do not like the "read he manual" statement but I cannot teach you the Lanquage and how to write programs. It is something you have to do it yourself.

Do you have a printed manual?

Start by flashing a LED, as trivial may sound this.

I even do this when I change PIC micro, just to be sure that I am in control of the new beast before I try anything more complicate.

Thankyou keith and Ioannis for ur contributions, pliz help me with the link for the manual and i try to follow it up. I dont have hard copy, mean while i wil make the changes u have told me
regards

[Ioannis]

How about obtain a legal copy of the PBP compiler?

I read through the manual and made the changes, now the new code is succesful with 16f84 but i wanted the same message to be sent to two phone numbers, pliz help me and check the code below;

code:

PushButton var PORTB.0 ' Setup the name PushButton to mean PortB input 0

Main:

IF PushButton = 0 THEN SMS 'If button is pressed then run the SMS routine below

goto main ' however if the button is not pushed then just go back to the Main
' routine to wait for the button to be pressed

SMS: ' this is the SMS commands routine in order to send an SMS

SEROUT PORTB.1,6,["AT" ,13,10] ' send AT to phone followed by a CR and line feed

SERIN PORTB.2,6,["OK"] ' now wait until OK is received

SEROUT PORTB.1,6,["AT+CMGF=1" ,13,10]

SERIN PORTB.2,6,["OK"]

SEROUT PORTB.1,6,["AT+CMGS=+256782277658"]

SEROUT PORTB.1,6,[13,10]

SERIN PORTB.2,6,[">"]

SEROUT PORTB.1,6,["BUTTON HAS BEEN PRESSED!"]

SEROUT PORTB.1,6,[26] ' this is ASCII for Ctrl+Z of which completes SMS sending

SERIN PORTB.2,6,["+CMG"] ' then PIC should receive +CMG from modem

SEROUT PORTB.1,6,[10] 'ascii code for a line feed

end

Something like this?

PushButton var PORTB.0 ' Setup the name PushButton to mean PortB input 0

Main:

IF PushButton = 0 THEN SMS 'If button is pressed then run the SMS routine below

goto main ' however if the button is not pushed then just go back to the Main
' routine to wait for the button to be pressed

SMS: ' this is the SMS commands routine in order to send an SMS

SEROUT PORTB.1,6,["AT" ,13,10] ' send AT to phone followed by a CR and line feed

SERIN PORTB.2,6,["OK"] ' now wait until OK is received

SEROUT PORTB.1,6,["AT+CMGF=1" ,13,10]

SERIN PORTB.2,6,["OK"]

SEROUT PORTB.1,6,["AT+CMGS=+256782277658"]

SEROUT PORTB.1,6,[13,10]

SERIN PORTB.2,6,[">"]

SEROUT PORTB.1,6,["BUTTON HAS BEEN PRESSED!"]

SEROUT PORTB.1,6,[26] ' this is ASCII for Ctrl+Z of which completes SMS sending

SERIN PORTB.2,6,["+CMG"] ' then PIC should receive +CMG from modem

SEROUT PORTB.1,6,[10] 'ascii code for a line feed

'---------- second number------------

SEROUT PORTB.1,6,["AT+CMGS=+000222333666444"]

SEROUT PORTB.1,6,[13,10]

SERIN PORTB.2,6,[">"]

SEROUT PORTB.1,6,["BUTTON HAS BEEN PRESSED!"]

SEROUT PORTB.1,6,[26] ' this is ASCII for Ctrl+Z of which completes SMS sending

SERIN PORTB.2,6,["+CMG"] ' then PIC should receive +CMG from modem

SEROUT PORTB.1,6,[10] 'ascii code for a line feed

end
