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 need a straight cable.
Thank's for your reply but i found this article "">www.commentcamarche.net/.../affich-24572614-cble-serie-droit-ou-croise", it's in french and it says that we need a crossed RS232 cable to connect a board to PC so the board's Rx is linked to the PC's Tx. I'm confused. Please help me.
try a crossover cable. if it dont work try a straight cable. rs232 is tough. it should not blow things up.
My problem is that i need to test a microcontroller code that involves sending string to the PC. If i don't know what kind of cable i need, i will never know the origine of the mistake, is it my code or the cable.
Pleeeaaaaaaaaase help !
What kit is it?
it's "LPC1788 Developer’s Kit".
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.
