[ARM] Interfacing GPS module for LPC2148 Micro Controller

[K Srinivas Pavan Kumar]

Hi.
can anybody help me by providing me the interfacing of GPS module with LPC2148

Hi,

The interface between the GPS module(specific manufacturer) & LPC2148 is the
serial communication like UART.

The module continuously sends that serial data containing the location parameters like
longitude & latitude etc...

In the serial data string first six bytes matches with the string like ($GPGGA)
then it is considered as valid data & perform string manipulation to extract data from
specific locations in string.

If the data string first six bytes doesn't match ($GPGGA), then should discard that
& considered as invalid data.

In this critical part is to establish communication between the micro controller &
module.

I want to see the latitude and longitude values in my LCD
In which I have seen the values for atmega using the AVR board

Hi,

Step 1: you should up your micro controller board with specific frequency.

Step 2: Implement & check GPIO's.

Step 3: Implement UART driver & perform the echo test with help of terminal.

Step 4: Choose 16 X 2 LCD & implement basic LCD driver.

Step 5: Send data to the LCD from PC with help of UART driver & check it.

Step 6: Implement the GPS interface driver with micro controller with help of UART driver.

Step 7:write your application as per your need i.e longitude, latitude etc..data from the data string
from the GPS module & perform string manipulations & can display that values on 16 X 2 LCD help
of implemented LCD driver.

Step 8: I think it's fulfill your need, in development phase first need to develop the basic interface &
check them, and should concentrate on application development.

Thanks for the info. and One more question
Is this for any kind of GPS module

Hi,

It's generic info, not related any specific module.
