Publiquei o primeiro relato de experiência com hardware no blog 🔧

O Hello World do hardware: piscando um LED com ESP32, protoboard, VSCode e PlatformIO.

Tem circuito, código, problema de ambiente Python e o erro clássico de protoboard que só você percebe quando monta tudo com jumper na mão 😅

O Hello World do Hardware: Piscando um LED com ESP32

O blog tem bastante conteúdo sobre software — princípios, boas práticas, Python, APIs. Mas há um lado da computação que sempre esteve no horizonte: o hardware embarcado. Este é o primeiro relato de experiência nessa direção, e começa pelo início: o famoso Blink — o Hello World do hardware. A ideia é simples. Pegar uma ESP32, um resistor, um LED, montar o circuito numa protoboard e gravar um programa que faça o LED piscar. O que parece ser coisa de uma tarde revelou algumas surpresas que valem ser registradas.

And here is my published dissertation @umphy, about quantifying the natural CO2 exhaust at the Starzach site in Southwest Germany (my result: ~10t/d):

I used a lot of #FOSS software and hardware for all of it and it was amazing. Honorable mentions: #gitAnnex, #dataLad, #KiCAD, #OpenSCAD, #PlatformIO, #Arduino, #TexLaTeX. I just wish I'd used #nix / #nixOS sooner.

Finally have the colour boot image now working with a placeholder image 🙌🎉

Continued the setup where the images are stored in flash ROM so the filesystem will be solely for badge images. And the boot image include is driven by a preprocessor define at the board or screen level.

I love messing with #esp32

It's alive! Inverted, but still working ☺️

I now have the different screen modules be able to define a Boot Image, which will then include the relevant header and data from PROGMEM to show when booting

I really love working with #esp32 and #platformio

PlatformIO is a Ukrainian Project. Please help us stop the war 🙏

Hi, the Peaceful World 🤗 We receive a lot of emails and messages on what will be with PlatformIO Project in the future. We collected all answers in one post. Quick answer The war should not affect PlatformIO Project in the future. Yes, PlatformIO is Ukranian Project, and the R&D team is still located in Ukraine (for security reasons we will not go into details about locations). We experience the same problems as other Ukrainians (see https://www.bbc.com/). History Russia (sponsor of te...
