ESP8266 Espressif SDK programming in C++

Intro Are you a C++ crazy fan? I'm! don't be shy. I can't imagine life without programming in C++, so now that I'm getting into IoT I wanted to explore the feasibility of using C++, after all programming ESP8266 in the Arduino IDE you can, why can't we on the official SDK? Out of the…

Non-blocking ADC converter class

The built-in analogRead() function blocks until the conversion is ready; for most scenarios this behavior is ok. However, for a high-responsive systems such behavior would be unacceptable. Another reason I wrote this small non-blocking class is because I bought a lcd-keypad shield, and then I built some improved clones: The keypad is implemented through an…

System-tick for the Arduino platform

A real embedded system needs a system-tick, and Arduino doesn't have one ... No, the yield() function is not a real system-tick, so I've swimmed a little bit into the code so that I get a real one. This is my progress. In the file hooks.c we need to add a place holder for our…

Building a solution from the command line

The Arduino's IDE is just awful. Period. To write sketches is awful as well. Scketches make me sick. Hopefully we can build our solutions from the command line, directly from the main() function, even using our favorite code editor, VIM for me. A more-in-depth tutorial on this topic can be found here. Installing Arduino We…

Building the Optiboot bootloader

The optiboot source code blundled along the Arduino package is out of date; it means, it doesn't compile with the newer GCC releases. I got this similar situation, while trying to build my own release as of march 2018 (AVR-GCC 4.9). As it was suggested in the post I got the latest release on github.…

Introduction

The primary goal of this blog is to keep track of my advances on using Arduino in a proffesional way; of course I hope all that info is useful for you.
