My Maker Faire Rome 2016

October 30, 2016

1

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 […]

Maker Faire will come to Rome in the weekend of 14-15-16 October 2016, and I plan to go there. The faire format is  by Make Magazine, and gathers the makers from all around the globe, so that they have the possibility to interact and showcase their work and their art. The maker movement has gained traction […]

STM32 Nucleo: access SD cards with C standard library

July 3, 2016

1

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 […]

DNS client on STM32 Nucleo and W5100

December 13, 2015

I am still working on a device consisting of STM32 Nucleo F103RB with a W5100 Ethernet shield. This time I included a DNS client, so that the device can connect to a server by knowing its name. The name resolving can be invoked by using the POSIX functions getaddrinfo and gethostbyname. DNS queries can have different […]

DHCP client on STM32 Nucleo and W5100

December 7, 2015

I am still working on a device consisting of STM32 Nucleo F103RB with a W5100 Ethernet shield. This time I included a DHCP client, so that when the device is attached to a network, it will ask for an IP address instead of being statically allocated. The DHCP protocol follows the RFC 2131 and RFC 2132, and […]

Update on POSIX socket library for W5100: client and server for TCP or UDP

November 22, 2015

I am writing a library that implements POSIX sockets, also called Berkeley sockets, for my ST Nucleo+Ethernet shield setup. The functionality that is currently in place, as for the source code on GitHub, allows for TCP client/server connections and UDP client/server communication using Wiznet W5100 chip resources. The interface is not complete, but what’s in place is taken as literally as I […]

In less than two weeks the Maker Faire will come to Rome. It’s a 3-day gathering of makers, hackers, companies and hobbyists with the passion for electronics, programming, manufacturing, artistry, learning and creating. There will be some practical workshops, tons of lectures, and bigger talks called “cortocircuiti” (shortcircuits). It will be hosted in the University of La […]
