I would like to puck up this time an easy programming on MCU for child or dummies.
The program is going to be a LED Blinky program, it simply blinks LED’s.
Actually, you might have seen this type of articles somewhere.
I tried to show an MCU programming using development environment that is a free of charge, which is being used at work in an actual environment.
To get MCU working requires you to study an architecture of MCU how MCU works and what registers are.
Such study however is not interesting to most people, so I would like to get MCU to work without having to study it.
Of course, I would explain a basic thing if necessary how it works.
I will divide it in three parts, “Preparation”, “First off, try with the sample project” and “Let’s try programming by own yourself”.
Ok, let’s do it, then.

1 Prepare evaluation board
I selected LPCXpresso802 because it is cheap and easy to use, user-friendly board.
This board is really cheap and has a lot of LED’s, and you can play a lot with it. It is the best board for beginners.
In such sense, you might think that the board is not often to be used in an actual environment, but to the contrary it is highly demanded and it has been used in many applications as it is very cheap.
LPCXpresso802 board uses LPC802 MCU from NXP semiconductors.
参考：LPC80x NXP Semiconductors Web page
You can buy it from Electric hobby shop. But if you can not find it, you can buy it from NXP web site directly, too. Below button to lead you to NXP Semiconductors LPC802 page. Then, click “Buy”. If you buy it on line, NXP exports the board to your country.
OM40000 LPCXpresso802 board2 Download IDE (Integrated Development Environment)
NXP provides a completely free of charge Development environment, which is MCUXpresso IDE. You can program and compile it and even debug it with free of charge. There is no limitation of compilation size at all, it’s free to use completely, even if it is hobby, or even for work.

3 Installation of MCUXpresso IDE
Now that you are going to install MCUXpresso IDE.
Basically, there is no complicated things. Alll you have to do is to click “Next”.
Below installation is based on MacOS.
Install MCUXPresso IDE
Run MCUXpresso IDE
Run the MCUXPresso IDE. If your PC is MacOS, you can run it from LaunchPad.
When it starts up, you need to select “Workspace” that is the place for work to program for your project.
You can select the default workspace if you are not familiar.
This “workspace” can be any place where you want, just make a folder for the workplace anywhere.
5 Download LPC802 SDK
MCUXpresso SDK needs to be built for specific device you want. There is a SDK Builder page you can built for your target devices.
MCUXpresso SDK Builder page
This is the end for downloading SDK package.
5 Installation SDK
Long way, but this is the last step
Once you downloaded the SDK, it is supposed to be Zip file. Now that you can drag and drop it into MCUXPresso “Install SDK’s” tab as you can see.
Then, the SDK will be automatically properly installed.
At the end
This time, I showed how you can download MCUXpresso IDE and SDK, then you are now ready to play with LPCXpresso802 board.
From now on, you will actually get the board working.
