NXPTM LPC2XXX and LPC17XX / Re: UART menu
« on: June 04, 2010, 09:32:29 PM »
Hello Mark,

Thanks for your replies.
One query,in your pdf,on pg 14 there is a red warning that the code will hang if there is no GLCD connected.
I do not have an LCD connected on my system,is that why there I am not getting anything on the UART ?


With regards
Thomas

Hello Mark,

Thanks for your reply. Actually it's a board made by my colleague which we are bringing up.So I am not 100% sure the hardware is working right.
The board is based on the Olimex LPC2478 board.So far I have the ISP and UART working.Now I wish to check the ethernet functionality.

When the board is powered up it sends "Hello, world... LPC2XXX" to the only serial interface on the board. This required a cross-over cable as you probably know if you have used the UART before.
 I am using the same COM port (UART0) and the same cable which is used to flash the software with flash magic.I hope you are meaning the UART (com port) cable and not the ethernet cross over cable ?

Flow control XON
High water 80%
Low water 20%
Hyperterminal kind of terminals don't seem to have this settings.Can you clarify this please ?

Are there any documents which explain how to set up the TCP/IP on the PC so as to be able to see the page ?
The spark fun discussion implies that the board needs to be setup through the UART before data can be received by the browser.

Regards
Thomas

I am using a 12MHx XTAL on my board.

NXPTM LPC2XXX and LPC17XX / UART menu

Hi All,

With reference to Kevin's post here :
http://forum.sparkfun.com/viewtopic.php?f=11&t=21981&start=0&sid=8176dd08b1ff780d08d1bf52b6456e79
Are the UART connection details ( baud rate etc. ) specified anywhere in any pdf ? I am using a terminal program Terminal ( Br@y ) but I could not get the menu which Kevin mentions.
Just to check I used another small program which sends a string "Hello World" and it works fine.
Any suggestions ?

Thanks
Thomas
