6. Embedded Programming

Now we are gonna learn about programming, or at least put in practice some of the stuff I learnt this week

Okay, so what does "Embedded Programming" mean?

As far as I understand, it refers to the process of writing code for embedded systems. Embedded systems are specialized computing systems that are designed to perform dedicated functions or tasks within larger systems. Unlike general-purpose computers, embedded systems are often part of a larger device or product and are designed to execute specific functions, usually in real-time. Since this is a really interesting subject, I invite you to take a look at our group assignment where you will find further comparison of the performances and development workflow for different architectures and you will be able to take a look on the different datasheets of the microcontrollers found at FabLab Puebla.

HARDWARE

Now let´s get to code… First, let´s get my cable type C and plug my device.

Open ARDUINO IDE

Find my port, and we are ready to go.

Now this is my thought process:

So, with this, I had to write my ideas on code them on the code.

I had one mistake, did not know what was going on, it turned out to be this mistake hahaha, kinda dumb.

Literally missing a braket hahaah

But I got these results:

the code:

My Neopixel wasn’t working, that´s where I remembered that I had to configure it, and download some drivers, sooo:

I followed these steps: Sketch > Include Library > Manage Libraries; searched for “Adafruit_NeoPixel” and just installed that…

Now, I got hands on it, and I used this code:

And got these pretty results, pretty good, I achieved what I aimed for… I was going to sleep but I remembered that the neopixel could change colors, soooo, using a code I ´ve got from the group assignment as inspo, I mixed my code and this new code.
