Rocco Marco was born in Italy in the 1987, he graduated “Summa cum Laude” with a Master Degree in Electronics Engineering.
He is currently work at Analog Devices as Senior Central Application Center Engineer with particular focus to Embedded Systems and High Precision Converters.
He authored more than 30 article on PLAY Embedded about Embedded Systems and he is actively contributing to different open source projects.
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 ...
In our minds, we have always seen SEGGER debugging solutions like a professional but costly tools: a debugger to perform advanced operations but definitely too much for a student. Some time ago we heard about a new version of SEGGER, the J-Link EDU, which is cheaper and addressed virtually to ...
The STM32 Nucleo-144 is a new series of development board by STMicroelectronics. It is the third announced series titled Nucleo. Each Nucleo-144 share the same pin map for each board and features a new connector named ST ZIO which is compatible with Arduino Uno Rev3 connector.
This new series ...
BUZZ Click is a click board with a mikroBus form factor. It is substantially composed of a piezoelectric speaker having a resonant frequency at 3.8 kHz: this means we should expect best performances at this frequency. Let’s take a look to the principle of operation of DC and AC buzzer.
A ...
In this tutorial we are going to see how to connect a STLink v2 debugger to a Clicker 2 for STM32 enabling users to do debugging which could be very useful in development phases. A debugger is a computer program which is used to test and debug another program usually named Target.
In embedded ...
