Hi everyone, I'm trying to interface the GSM to PIC16F628A. The GSM module runs on 3.3v I use PBP and this is the code
Code:
Include "modedefs.bas" ' Include serial modes
'Definitions
DEFINE OSC 4 'for 4 Mhz
'DEFINE OSC 8 'for 8 Mhz

DEFINE HSER_TXSTA 20h 'hardware assign

DEFINE HSER_RCSTA 90h '

DEFINE HSER_BAUD 9600 'for 9600 Baud rate

DEFINE HSER_SPBRG 12 '

DEFINE HSER_CLROERR 1 '

TRISB=%00000000
PORTB=%00000000

' Send signal tp PWON
    HIGH PORTB.7
    PAUSE 500
    Low PORTB.7
    PAUSE 3000
   
start:
HSEROUT ["AT",13]                    'Send AT to modem followed by a CR
HSERIN 5000, start, [WAIT("OK")] ' wait 5sec to reply.
PAUSE 1000

goto start
End
The program simply return 'OK',how can I set it up so that I can see what the GSM is sending? Can I use PortC.6 to display the message va hyperterm?

Yes you can use portC.6 to send data to rs232 port.
or you can connet the TX , RX pin of MCU directly to hyperterminal  vai MAX232 pin
