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 ...
In this article, we will use a WeSU in some daily common scenarios. In this way, we will propose some case of use of wearable device, testing also its mechanical robustness and its sensitivity.
For our tests we will use the remote data capture feature provided by the smartphone app: this is ...
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 ...
At the recent event “ST = Life Augmented”, held in Milan during the Class Digital Experience Week, STMicroelectronics has raffled various development kits, for attendees who enrolled to the event through the Pepite blog. Apart to the famous STM32 Nucleo-64 board and some of its Expansion Board ...
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 ...
In this article we will resume the topic started with in “Detecting obstacle with IR Sensor and Arduino”. More in details, we are going to use the IR sensor like an objects counter.
The counter application is often used for:
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.
