Getting started guide?

Hi all,

I just got my LPCXpresso board with the LPC1769.  This is the first time I'm using an ARM based controller, and I'm admittedly completely lost :-P  Is there a guide to getting started with these things?

Here is a specific problem I can't seem to get around:

I have built the uart example in the example code, and it appears to be running on the board, but I can't tell because I can't actually connect to the board with my PC to get the data.  It's Windows 7, 64 bit, if it matters, but nothing appears as a USB-to-serial device on my system. 

Also, I can't flash the board -- it gives me that error 53 that other people on the forum had, where my license is apparently not sufficient.  I've tried re-installing and re-registering but no dice.

Hm...any thoughts?

MIKE

Both links are great for starters, like myself.

However, I think NXP should make a transition tutorial for old 8-bit programmers, like a dumbed-down version for 32-bit programmers. Something like that would have made my life so much easier.

Hi,
Here is an App note for migrating into LPC17xx

Kind Regards

Have a look at these:
AN237 - Migrating from 8051 to Cortex Microcontrollers
AN234 - Migrating from PIC Microcontrollers to Cortex-M3
AN179 - Cortex™-M3 Embedded Software Development

Hi

ARM Cortex is not as difficult as it seems to be at first glance. But having a lot, and mix-up, of options for tool-chains, vendors, standards (CMSIS), programmers, etc, makes the picture obscure.

However, the guys from ARM took into consideration your desires (to make the life easier with 32 bit core controllers), that's the reason Cortex-M0 family to exist. This family is not only the easiest, but also is the natural replacement for 8 and 16 bit application replacement.

Maybe you should start with a member of this family. NXP offers a LPCEXPRESSO board, IDE and tool-chain for the LPC1114 uC (at very affordable price).

Hi again

I found it. Try this two links:

http://knowledgebase.nxp.com/showthread.php?t=2446

Good lock :)

Can you get an oscilloscope (or at least a couple of leds) in order to spy Tx/Rx signals?

Also, LPCXPRESSO has an option in which you can choose to use real Tx/Rx signals out of the chip (so you can make a real connection with a PC's serial port), and another option to use a virtual port (a console inside the IDE) but you won't get Tx/Rx signals out of the chip, (so you won't see anything when getting disconeected from the IDE).

Right now I'm looking for that option. I used it few days ago, but I don'd remember where it is. ASAP I find it, I'll let you know.




Also, I can't flash the board -- it gives me that error 53 that other people on the forum had, where my license is apparently not sufficient.  I've tried re-installing and re-registering but no dice.
