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 […]

Work in progress: POSIX socket library for W5100

October 28, 2015

In a previous post I connected a Nucleo board with an Ethernet shield, with the SPI wired between the STM32 and the Wiznet W5100 chip. I am now in the process of writing some C tests for it on a GitHub repository, and in particular a socket library that tries to conform to POSIX specifications. At this […]

Arduino Ethernet shield on STM32 Nucleo

I have a clone of the Arduino Ethernet shield R2, and I already hooked it up on an Arduino Uno, as explained in a previous post. But I also have an STM32 Nucleo-F103RB board, which is similar to Arduino with respect to many of its pins, so I wanted to try this shield with it. The main […]

libopencm3 on STM32 Nucleo board

This article is part of a series about developing for STM32 micro-controllers on Linux. A few days ago I talked about libopencm3, an open source library to access Cortex-M functionalities and peripherals of many micro-controllers, especially STM32 variants. I wanted to use this library to develop on a Nucleo board that I have in my hand, […]

ST Nucleo F103RB works with OpenOCD 0.8.0

Full disclosure: I work at ST Microelectronics, but what I write here is purely my opinion and my work, conceived and conducted in my spare time. The ST Nucleo boards are development platforms mounting an STM32 microcontroller, made for the same enthusiasts that are attracted to Arduino and the like. They have between 64KiB and 512KiB of […]
