During Embedded World 2017 in Nürnberg I was lucky to get a handful LPC800-DIP boards. To get all students who were lucky to get one, here is a tutorial to make that very exciting ‘blinky’ application on that board:

MCUXpresso IDE Series

This article is part of a series to get up to speed using the new NXP MCUX presso IDE. Published so far are:

Outline

This article shows to run a first ‘blinky’ (toggling LEDs on the board) on the LPC800-DIP board using Eclipse (MCUX presso IDE) and the NXP LPCOpen library.

You need

LPC800-DIP board or any other LPC8xx board, in that case you will need to change the LED pins in the source code
MCUX presso IDE V10.0.0 b344
Micro USB cable
SWD/JTAG debug probe like the LPC-Link2

he LPC800-DIP board does not contain a debug interface, but the USB-2-UART bridge which can be used with the FlashMagic (by Embedded Systems Academy) tool to program binaries. As I want to debug my application, I’m not using this tool in this article.
A link to all the project and source files is provided at the end of the article

LPC800-DIP Board

The LPC800-DIP board is a tiny board with the NXP LPC824 microcontroller on it:
It has the LPC824M201JHI33 on it (32 bit Cortex-M0+, 32 KByte Flash, 4 KB RAM) in breadboard friendly pin out. The microcontroller can be programmed using SWD or through the Silabs CP2102 UART-USB bridge: with pressing the ISP button I can program the device through the USB connection to the host and the Flash Magic utility.

SDK: LPC Board and LPC Chip Projects

To start with the board, I need a software library or SDK. For the LPC800 NXP provides the LPCO pen library. That library already is installed with the MCUX presso IDE:
Alternatively, I can find them here: http://www.nxp.com/products/software-and-tools/software-development-tools/software-tools/lpcopen-libraries-and-examples/lpcopen-software-development-platform-lpc8xx:LPCOPEN-SOFTWARE-FOR-LPC8XX
I import the library project into my workspace using the ‘Import project(s) from file system…’ from the Quick start panel in the MCUX presso IDE:
Then browse for the LPCO pen archive file:
Press Next. I get offered a selection of projects to import. I need the chip library which I select:
The ‘chip’ library as the name indicates supports the given chip. I could as well import the board library (but that one would be for that board) or the example projects. For my blinky project all what I need is the chip library and I will do my ‘board support’ for the LEDs.
Press Finish, and the chip library shows up in the workspace:

Creating Project

The next step is to create a new project for the board. I use again the Quick start panel with ‘New Project’:
Select the LPC824:
Press next. Select LPCO pen C project:
Press Next and give a project name:
In the next dialog it should detect the chip library I have present in my workspace:
Press Next. In the next dialogs I use the defaults until I get to the point to finish the wizard and the project gets created in the workspace:

Schematics and LEDs

Checking the schematics of the board, I can see tha the three LEDs on the board are connected to PIO0_17, PIO0_16 and PIO0_15:
The LEDs are connected with the cathode side to the microcontroller. So this means I have to put the ping LOW to turn then LED on (the LEDs are LOW-ACTIVE).
