GPS reading – junk displayed

[sampoornam]

Hi

I am using PIC18F2550 with GTPA010 module.

I am just trying to display the received data, but some junk is displayed.

What could be an issue.

If required I can post th code here.

thank you.

Hi Sampoornam,

Please post the code and circuit diagram also.

I tried the code, given for GPS to 18F4550 interface, I used 18F2550 and GPS is GTPA010.

Nothing received

But when I tried the code similar to RFID reader (interrupt based), it displayed junk.

Ciruit is not having any great things, the RX of PIC is connected to TX of GPS receiver

Please give your inputs

Hi Sampoornam,

Does your GPS module has DB9 connector?

There should be so many things in the circuit, like a max232 IC between the PIC and the GPS module as an example. If you are using a device which is 3V operated, there should be a 3V to 5V level shifter between the PIC and the GPS device.

The coding is the one last step in the process of doing a microcontroller project!

Make sure that you are using the same baud rate of the GPS module.

I just receive the data at RX of  PIC18F2550, so level conversion is not an issue.
