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 […]

Arduino Ethernet shield on STM32 Nucleo

I started playing with an Ethernet shield for Arduino that I bought at a faire. I noticed that the shield itself is not original, but it’s a clone of the Arduino Ethernet Shield version 5.0, also identified as revision 2. The shield provides Ethernet connectivity and has an SD card slot to provide non-volatile memory […]

ARM 64-bit developer kit on the way from AMD

The news: AMD Announces the Availability of 64-bit ARM Opteron Developer Kits It sure sounds cool: 4 or 8 cores, 16GB of DDR3 RAM, PCI-Express 3, SATA 3, 10Gb Ethernet, microATX form factor and full Linux distribution (Red Hat) already running on it. I feel a little disappointed about a couple of things: I didn’t […]

Arduino YÚN is a new product in the Arduino family. It’s a board with the same form factor as the typical Arduino, but contains an application processor running Linux, and modern flexible connectivities such as Ethernet, WiFi and USB. Here’s an introductory video from the creators: The Arduino YÚN features are described in a blog post in the official […]
