A close look to ChibiOS demos for STM32

A close look to ChibiOS demos for STM32

In this article we are going to take a deep look to ChibiOS default demos explaining how they works. We will also see how to create a new project and how to modify it in in order to create our own applications.

ChibiOS default demo are usually composed by some different folders and files. As example, in figure we can see the resources of the default demo for STM32 Nucleo F401RE. In general all the ChibiOS’ projects are characterised by a similar anatomy.

All demos have some folders, some configuration headers, a source file named main.c and a makefile. Additional notes continue reading...

From 0 to STM32

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 push data through the Internet: this phenomenon, this network of Smart Things, is commonly known as the Internet of Things or IoT. The spreading of the IoT is substantially due to two main con-causes:

the evolution of Microcontrollers which are increasing their performances while their price is continue reading...

ChibiCube hardware explained

By this article, we will show schematic of ChibiCube in order to understand how it works and hot it has been designed.

As mentioned in the previous article, ChibiCube addresses all its LEDs through the combination of anode and cathode signals. Each floor of the cube is configured as common anode, while the various cathode signals are separately connected to the outputs of the Shift Register. Setting the anode voltage to a value equal or greater than the high logical threshold of our SR, for the same principle illustrated in the tutorial Meeting SPI, we can address single continue reading...

Introducing ChibiCube

Introducing ChibiCube

ChibiCube is a 3D LED matrix 8x8x8 composed by monochromatic LEDs individually addressable: that means not only every single LED could be in a ON or OFF state but everyone could be set at different light intensity.

In December 2012, students Ciro Domenico Pagano from University of Salerno, Antonio Galano from Federico II University of Naples and Vincenzo Brillante from University of Sannio start their training at Naples site of ST Microelectronics.

In order to understand uses of ChibiOS and STM32 MCUs, their Tutor Giovanni Di Sirio suggested the design of a small 4x4x4 continue reading...
