After a few days of hard work I was able to resume the project. I did not remember that I had not tested "El Pico".
Not because I have any doubts about its good quality, it's because of my poor pin soldering skills. I have "Elektro" hands so I decided well to protect the "El Pico" with the acrylic cap. The Pin-Out sticker helps guide me, because the pin numbers are below the board.
The first step to test "El Pico" was to select the programming language that I am going to use. I decided on Micropython because I don't know much about that language, okay, Arduino is wonderful, but everything has already been done, the important thing is to learn a little more, maybe I myself have decided to go the hard way, but the important thing is to learn and have fun.
The second step was to select the IDE to use, I decided on "Thonny" because THE OFFICIAL RASPBERRY PI PICO GUIDE recommends it.
The third step was to load the Micropython firmware on "El Pico". It was easier than I thought, although there are two ways to do it.
The obvious one is when you connect the card via the USB cable, the PC recognizes it as a storage drive, so if you already downloaded the firmware version you just have to drag and drop.
The other option is to open "Thonny" and let it help you, this is a very friendly IDE and it recognizes that you don't have a Micropython firmware installed on "El Pico".
The third step is to create a first test program, as I said at the beginning of this blog, just to make sure that my welding job does not fail. But since I haven't decided which hardware I'm going to use entirely, I just tested that my electrostatic hands didn't cause damage to the card. So for now the classic Blink works for me.
As you can see in the code, it wasn't the classic Blink, because I like to give flow to my codes, but the result is the same.
Its alive. The pick has survived the high temperatures of my soldering iron and my electrostatic hands. That means that the road will be entertaining. I already have some pieces of hardware in test, but they will be for the next Blog.
