Arduino-esp32 Basic course – Getting started – Chapter 1
First of all, this small series of blog posts, assume you have installed and are familiar with Platformio IDE to edit and upload code to your Espressif chips. We ‘ve covered in another post the installation and getting started part with this nice IoT editor. Please refer to this section of Platformio to get the…

Trying out Waveshare E-Paper ESP32 driver board
In my pursuit to make the CALE displays as small as possible but also to learn how different boards interact with Epaper I got last week an Waveshare E-Ink ESP32 driver board. Not all the boards need to use the default SPI GPIOs of the ESP32 and this was one of this cases. Opening the…

Hackaday projects update: CALE Eink Calendar and udpx
I must say although I’m not proud of all the projects I tried to document in Hackaday I do like a lot udpx and Remora, that are made initially to control Addressable LEDs, but they could be expanded and used for another uses. CALE This is actually an old project for the agency I work…

Cordova cross platform mobile applications
After the small Chrome App experience that resulted in a very compact app that reads Video and sends an UDP binary stream to ESP32 Led controllers I decided to start learning how to program a real mobile app. Real because I find that the way to do it must end in the App Store and…

Met Remora a simple firmware and language to launch addressable led animations from ORCΛ
Remora listens to UDP short commands to trigger LED Animations. Receives ; commands from ORCΛ As a side fun idea while learning Nodejs and while working for a bigger and more complex project with my partner Hendrik I programmed Remora just to have an easy way to launch animations from ORCΛ If you want to…

UDP + Brotli compressed messages on Microcontrollers: Sending more with less
I wanted to document on this paper my efforts on researching a way to send efficiently a lot of data to an ESP32. One of the attractive features of UDP is that since it does not need to retransmit lost packets nor does it do any connection setup, sending data incurs less delay. That made…

Espressif ESP-Mesh updates their App with a new UX
About a month ago I started learning to use ESP-IDF and got very interested in Espressif Mesh Lamps. It’s a lot of fun for me to create my own ESP-Mesh LEDs lamps with this technology. But as with everything I touch that is open-source, apart of being a user, I try to collaborate and made…
