Rocco Marco was born in Italy in the 1987, he graduated with Merit with a Master Degree in Electronics Engineering.
He currently works at Analog Devices as Staff Field Application Engineer in the Automotive market.
He authored more than 30 article on PLAY Embedded about Embedded Systems and he is actively contributing to different open source projects.
The Pulse Width Modulation (also known as PWM) is a digital modulation technique which uses duty-cycle of square waves to encode information. In communication field PWM surrendered to more advanced communication technique which uses more complex waveforms showing better noise rejection ratio ...
A microcontroller is a system which works on bits and bitstreams more than analog signals, anyway, those signals are still widely used in many fields especially in audio and power applications. An Analog to Digital Converter (or ADC) is a system that converts such kind of signals in a sequence ...
The C programming language is clearly an imperative programming language not designed to be object-oriented. Anyway, the object-oriented approach remains something much more related to the design and mindset more than to syntax. The ChibiOS/HAL is an Hardware Abstraction Layer which design ...
The serial communication in asynchronous mode is one of the simplest and most used methods to exchange data between a microcontroller and other devices. Such kind of communication can be achieved through a Universal Synchronous/Asynchronous Receiver Transmitter (or USART) as well ...
The STM32 is equipped with an extremely flexible General Purpose Input Output (or GPIO) peripheral allowing to configure each Input/Output independently. The IO is the simplest interface between the STM32 and the outside world.
As we said in the article “From 0 to STM32“, there are many ...
In this article, we are going to take a deep look to ChibiOS default demos explaining how they work. We will also see how to create a new project and how to modify it in in order to create our own applications.
A ChibiOS’ default demo is usually composed of some different folders and files. ...
In this article, we are going to set-up a ready-to-use Eclipse-based toolchain named ChibiStudio for the development on STM32. We will also explore this development toolchain explaining some basic operations necessary for daily development. So we will introduce the ChibiOS project, we will ...
Nowadays, we are surrounded by smart objects capable to do incredible things. These objects, known as Smart Things, are now able to communicate over different wired and wireless communication channels. The obvious consequence is that these objects are able to get and to push data through the ...
HC-SR04 is a commonly used ultrasonic sensor which is capable to detect obstacles in a range of 2-300cm. The sensor looks like a small PCB having two metal cylinders on the front-side and a small circuit on the back-side (see Fig.1).
In this article we will provide a simple demo to use ...
The HD44780 is a de-facto standard controller for display. We have already use it providing a source code to use a 16×2 LCD with a STM32. In this article we will step over introducing an I2C backpack for that display. Of course we will explain how to edit old code in order to get it work with ...
First time I started to deal with a software a little bit more complicated than the one used to print “Hello World”, I have encountered some words like “versioning”, “revision”, “diff”, “branch”, “trunk”, “checkout” and I heard about certain software like “svn”, “git”, “mercurial”.
Do you keep ...
In the article “A close look to ChibiOS demos for STM32” we have briefly explained how multithreading works but in this article we want to discuss more in detail the mechanisms behind ChibiOS/RT. This article is addressed to those developers already experienced with this RTOS.
A single thread ...
