[lpc2000] CrossWorks UART example

[lpc2000] CrossWorks UART example

2004-02-21 by gokbektas

It works fine, but if I close serial port and re-connect with PC without
making anything on LPC, weird data appears at PC.
If I reset LPC, it turns to normal.
It happens with CrossWorks terminal window and my own serial
port monitor software 'common'.
Any opinion?

I retouched with the soldering iron to pins of baby, compare function or ISP utility confirms chip is programmed.
Leon, your code sent garbage characters at 9600 baud, I tried other baud rates also...
Then I recompiled uart example of crossworks then loaded to chip...
It is working! Now, I can play ;-)
Thanks a lot! I'll upload my board's picture to my personal website soon.

It looks like you have a problem with the flash memory. I'd replace the
chip, or try another board if you have one. I'm actually using a '2104, but
it shouldn't make any difference.

RE: [lpc2000] CrossWorks UART example

2004-02-21 by Paul Curtis

I assume that the serial data is being sent at full rate, so it appears
as a synchronous stream.  In this case, with no pauses, it's possible
for the UART to sync to a non-start/stop bit.  If you send your data in
bursts, you'll see possible some garbage data, and then the UART syncs
when it sees the stop and start bits with a bit of a breather in
between.

Re: [lpc2000] CrossWorks UART example

2004-02-21 by microbit

Paul's right.
What he means is that if you start up your terminal SW while the
serial data is being output from the LPC, it will interpret the first
high-> low transition on its RXD line as a start bit.
If the data being transmitted from the LPC doesn't have a pause
between stop bit and the next start bit, the UART in your PC won't
synchronise properly.
To "fall in" the datastream, the transmitted data must have at least 9
High bits, so the PC's UART can flush out its receive shift register,
and sync properly.
