Timer for UV box - final build - Hardware

Time to close also this project.
With the help of Roberto we did end up with a PCB, let's put it together.
This article describes some work on the hardware side.

Timer for UV box - final build - software

Once the hardware was ready, I resumed the code developed with Energia.


Let's see what I found.

Controlling a WS2812B LED

Just some brief notes about LED strips based on the WS2812B (for example this one).
The same LED is also used in the Adafruit circular ring LED (here a datasheet from Adafruit)

Technology changes

The market for embedded development is more and more complex and fast these days.
Every day there is some new platform popping up.
Is quite difficult to stay updated unless you have to do that for work.

Why sometime ...

... simple things does not work or just make you crazy losing hours and hours if not days  ?

Who work in the magical world of the software development, especially embedded or firmware, sometime find himself in weird situation, when something incredibly simple and trivial, simply does not work.
Why ?

A personal CI system

In this article I'm describing how to set up and configure a basic CI (Continuos Integration) system that can be used for many  things, based on an open source program called Jenkins.

Of course, for my projects to set up a CI  to build them is just little bit overshooting, but surely is interesting and fun.

Energia and MSP430G2553

Recently I had a little bit more deep experience with Energia and the MSP430G2553.
Here some notes about this experience.

Timer for UV box

Ok, here the deal.
The need is to develop a timer, faster, capable to control up to 16 UV fluorescent bulbs.
Up to 2 hours, 1 second precision, display to show the countdown and menu' management, digital encoder for input, pushbuttons/LEDs.

It can be done in thousands ways, but this time I'll try to put it together using Energia and a BIG help from Roberto.

MSP430 - Energia and Grove

I do have few Arduino around.
Like many people I bought some of them because ... well, I don't know, I guess at the time it was the news, to see what it is.
And I didn't like it much.
