The Molcajete Project 0.9.3 is here!

I'm proud to announce that The Molcajete Project 0.9.3 is ready to be downloaded. What the heck is The Molcajete Project? It's my attempt to bring together Arduino, FreeRTOS, and the availability of compiling from the command line. This project can convert your Arduino into real time! This release mainly comprises the lastest versions of…

The Molcajete project: where Arduino meets FreeRTOS

It's ready the bundle in which you can program your Arduino apps using the FreeRTOS kernel. You can download it from The Molcajete project The Molcajete project by Xavier R OVERVIEW The aim of this project is to program Arduino apps using the world's most downloaded real time kernel, FreeRTOS, in a terminal through Arduino-mk…

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…

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.
