[SOLVED] GPS interface with LPC2148 please help .

[pawan kumar]

Hi Selvam,

How do you interface LPC-board with ecompass to get data out in LCD? (do you use serial port?)

and to display the data in PC(hyperterm) you may use serial interface.Its simple.

Yes pawan. I have interfaced LPC and ecompass using serial port(USB to serial converter., i.e USB side is connected to laptop) . And to display the data in hyperterminal shall I use the same USB to SERIAL CONVERTER after fusing the program in flash. Is my approach is correct.

And programming part is the same logic applied by you in this thread ?

please do the needful

Thanks & Regards

Hi selvam,

I guess you use USB to serial converter to program the LPC board.That's fine.

USB side is connected to laptop

Yes you can use the same serial port to display data in hyperterminal.

I was asking you about this interface.

And to transmit a byte of data to the serial port, use the function

void senduart0(unsigned char a)		  //sends a byte through UART0
{
while(U0LSR!=0x40);
U0THR=a;
}

My suggestion is test the serial communication separately ( transmit a byte )--(Just have a look at previous comments in this thread). after having it working, its easy to transmit an array.

Hope it helps.
