Hi, I want to connect a "LPC1788 Developer’s Kit" board to my PC. I have RS232 port in both sides. Should i use straight and crossed RS232 cable ? thank you in advance.
You stupid idiot. Do you want help or not?
I mean where does it come from? Who makes it? Is it a Keil product? Does the manual say?
I'm not going to waste any more time on a fool like you but if you really want assistance you better give some proper information.
"You stupid idiot."
Some people are more clever than others with words. How old are you? You often suffer net rages?
The solution is actually simple: if the evaluation board has a female connector, then you need 1:1 cable, because on the PC side it's male. If the board has male, then you need null modem cable.
Look chum. If you want political correctness and good manners then you should choose another profession.

I have seen just about any possible viaolation of the standatd. The above is "what it should be", not necessarily "what it is"

@Tam Martirchokeael,
Have you considered consulting somebody versed in mental health problems (and solutions)?
Erik,
I don't think that Keil will violate that standard on purpose. We also have Keil LPC evaluation boards and connecting the UART to the PC is one of the simplest things to do.
Sabi, does it already work? From my experience, the problem will start by just compiling code for a LPC. Keil has a total mess in the library for the various models. We had a LPC1758 and a LPC1315, which are not very different. But the files for the 1758 did not work with the 1315 and vice versa. Also, when comparing files with the same name, simple things like GPIO setup were totally renamed from one chip to the other. Apart from the fact that programming the LPC is a pita.
I don't think that Keil will violate that standard on purpose. We also have Keil LPC evaluation boards and connecting the UART to the PC is one of the simplest things to do. I have seen VERY reputable companies violate the standard. Also, I do not think Keil makes (and designs?) their boards, Keil is a software company first and foremost.
anyhow using "I don't think that ,,,," as a design practice can not be recommended.
I tried to build a code that i have, it work perfectly when i simulate it with Keil Simulator (Device: LPC1788). But when i burn the hex file into board nothing appears.
People,
I asked the idiot (sorry the OP) for details of the board. All he said was "LPC1788 Developer’s Kit". Is that a Keil product? I can't see it mentioned at http://www.keil.com/boards/cortexm.asp
We don't have a clue about the board or where it came from. It could be a cheap Chinese board with the wiring all swapped over.
So all other assumptions are just that. Assumptions.
The bord is "LPC1788 Developer’s Kit", it's an embedded artists product "">www.embeddedartists.com/.../lpc1788_kit.php"
This is what you must do:
1. look-up the pinout of the PC COM port (google);
2. look-up the pinout of the board's RS-232 connector (Please read the manual);
3. you should be able to take it from there...
Get (or make) yourself something like this for checking:
www.bb-elec.com/product11.asp
So why aren't you asking Embedded Artists, then?
This has nothing to do with Keil!
Working link: www.embeddedartists.com/.../lpc1788_kit.php (never put any punctuation on a URL; the forum will include it in the link - that's why the link in your post doesn't work).
It says:
"Included in Kit: ... • Serial number that gives you access to the support site for this product"
So why aren't you using that?!
It does seem a bit perverse that they incude a USB cable - which really is standard - but not an appropriate RS232 cable - of which there are many options & variations!
