Hi, i have bought the LPC1769 microcontroller, i have already installed the LPCXpresso develop software
but now i dont know to work witht it. I have seen examples code on mbed lpc1768 but when i try to write and run on LPCXpresso it is totally incompatible.

Also i have tried to find some references on internet but i didn't find enough, Do you know some reference guide in order to program on LPCXpresso for the LPC1769?

Thanks.

Google is you friend  ;-)  'LPCXpresso video' is showing a lot of helpful videos:

Hi,

don't click on these links, copy them as text and paste the text into URL bar of your browser, e.g.,

Anyway, why are you interested into LPCXpresso when it's outdated and has been replaced by MCUXPresso IDE?

>>Anyway, why are you interested into LPCXpresso when it's outdated and has been replaced by MCUXPresso IDE?

The SDK page for the MCUXPresso does not show anything for lpc1769, starts with lpc5xxxx.
Can MCUXPresso be used at all for lpc1769?

[danielholala]

Correct. This is because for LPC1769, there's no SDK. Instead, development support for LPC1769 is based on LPCOpen framework which is integrated into MCUXpresso IDE.

Screenshot MCUXpresso IDE 11.8.0:

In a later step select the appropriate LPCOpen archive:

Thank you Daniel,

It took me a while to get that all up and running. I did not expect dependencies between projects.
One problem still. I cannot find my board. It is probably a really old one.

Why not try to create a project based on this one:

I think the major difference is the debug probe on the board.

[hennep]

It is not available in my IDE

[danielholala]

So which IDE are you using? Does the screenshot show the "Create a new C/C++ project" wizard that's offered in the Quickstart Panel?

Do not use the link "Import SDK example(s)" from the Quickstart Panel.

Thanks again Daniel,

I did use the wrong dialog. In the meanwhile I can create a project for the LPC1769 that compiles ok.
When I create a "Run configuration" for the .axf file and click the run button, the axf file is rebuilt and nothing else happens. Do I need to install/setup a separate programmer, or did that come with the IDE?
The IDE does not even complain when I leave the development board unconnected!

I have been searching the NXP site for documentation but except for the LPC3154 schematics I couldn't find any "getting started" documents for this board. I hope you have the patience to get this noob started

[danielholala]

@hennep , I think I've never used the "Run" button. I rather use either the "Debug" link from Quickstart Panel or the button for the "GUI Flash Tool", see screenshot:

[hennep]

It's hard to unlearn habits. I've used the run button in Eclipse in both Android app development and in STM32Cube but I will get used to it.
It all works, the fun part starts right now

And read the (hardware) User Guide, a Microcontroller cant be programmed without understanding the hardware:

Read 'LPCXpresso v7 User Guide',  it's in your lpcxpresso folder  :O

If you don't find your lpcxpresso folder, download it here:

Examples are in your lpcxpresso/Examples folder  :O
