My Maker Faire Rome 2016
Two weeks ago I visited the 2016 edition of the European Maker Faire in Rome. The Rome fair can be reached easily with the train that goes between Rome center (mostly Tiburtina station) and the airport of Fiumicino. The whole fair has ten pavilions, and the Maker Faire managed to fill six of them with all […]

STM32 Nucleo: access SD cards with C standard library
July 3, 2016
The ST Nucleo is an Arduino-like board with an STM32 as the microcontroller, and many Arduino shields can be mounted on it. I recently played with an Ethernet shield for the network connection, but since the shield also contains a microSD card slot, I wanted to access the SD card to read/write files. I’d like to […]

Simple time synchronization for the Internet of Things
February 18, 2016
While adding HTTPS capabilities to my STM32 Nucleo board, I needed to solve the problem of current time. This is because TLS needs to check certificate expiration date, so we need a sufficiently accurate estimation of time. So I tried to understand what could I do to ask a network server about the time. I […]

HTTPS client on STM32 Nucleo-F411RE
February 4, 2016
One of my goal of the past months was to use an STM32 Nucleo board to get a webpage through HTTPS, using an Ethernet shield for TCP/IP stack. I was close last time, but I discovered that my Nucleo-F103RB did not have enough RAM. Now I have my hands on a Nucleo-F411RE that has 128KiB of RAM […]
