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.
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 ...
The Clicker 2 for STM32 is a compact development kit by mikroe (also known as MikroElektronika). This board is equipped with 2 mikroBUS socket that allow to connect the Click Boards. These boards, designed by mikroe, are small add-ons that allow to easily connect most common devices to your ...
In past, building OpenOCD under Windows was really complicated since it has a lot of dependencies and not was easily available under windows. With MSYS2 this task has become very simple and, if you need to use the latest stable version of OpenOCD in MSYS2, it is available as binary and could be ...
The joystick proposed here is much known between makers. It provides two axis and a key button and every axis is actually a potentiometer: that means axis data is analogue and we need to use ADC to read its positioning.
Potentiometers are provided of springs so, without forcing, wipers are ...
We have already introduced MAX7219 in STM32, ChibiOS and a 8×8 LED Matrix, so we are going to jump directly to code section. For convenience we just report link to documentation:
MAX7219 Datasheet
Note that even if pins are arranged in a different way, pin-out remains the same of the 8×8 LED ...
Using Infra-Red for remote control is a technology born in the 70’s and after 40 years it is still used because the good ratio performances-costs and low power consumption. IR remote require a line of sight, because of that latest remote includes bluetooth technology.
Today it is possible to ...
Widely used in sound mixers, the slider can be used as input for many applications. There isn’t so much to say as this device is made by two potentiometers working together. Indeed, when the cursor slides, it changes the position of two side potentiometers.
The slider shown in Fig.1 has six ...
The MAX7219 is a compact, serial input/parallel output common-cathode display driver. Included on-chip there are a BCD code-B decoder, the multiplex scan circuitry, segment and digit drivers, and an 8×8 static RAM that stores each digit. Only one external resistor is required to set the ...
We already talked about ChibiOS/HAL design and its multiple architectures support. This is very important for regular developers: imagine a scenario in which you design an application using a certain MCU and after a first stage you decide to upgrade your application. Imagine also that hardware ...
