gps_data var byte

serin2 TX,16468,[WAIT("$GPGGA"),str gps_data\6]

Your gps_data is defined as a single byte. You want an array to work with, so you should define it as something like:

gps_data var byte[6]

hi thanks for pointing that out but still nothing.

i changed my code to serin2 TX,84,[WAIT("$GPGGA"),WAIT(","),DEC2 H,DEC2 M,DEC2 S]


PAUSE 200

HIGH PORTC.0
PAUSE 200
LOW PORTC.0
PAUSE 200

SEROUT2 PORTC.1,16468,[dec2 H, dec2 M, dec2 S]

GOTO MAIN

still nothing

the gps module is connected properly it is receiving 3.3v so unsure whats going on

do you no if it must have a backup battery, because at the moment i don't have that pin connected to anything

What's your hardware setup? Got a picture? Can you show the whole code? I wonder what your TX pin is doing with the serial in, but I can't tell from here.

The code you just posted is not inverted, so I assume you have the max232 back in?

hi

my brother has my cam at the moment, i will get it off of him tomorrow.

quick question - i'm using a 16F870 will it accept voltages as low as 3.3v on an I/O pin

What does C.0 do? does it flash an LED?

if its used for something else, then it might be a good idea to ad an LED and make it flash on and off as your program runs. I find that it helps me know where the program is getting hung up or if its running at all..

One other thing, and im not sure if its right or not, but wheni use an external osc i need to set it to HS not XT.

hi yes portc.0 is used to flash an led, so i know its recieving serial data.

the pic micro it self is running as it output's a test message to the pc's serial port and that is sent fine

[rondo2]

Also

i measured the voltage on the pin which transmits the serial data fron the gps module, and it was only 1.5v, now is that normal.

the pic micro will not see the data at such low levels will it ?
