Embedded Systems Conference 2016 Schedule – April 13-14

The Embedded Systems Conference 2016 will take place in Boston on April 13-14, and the organizers have now released the schedule, minus some keynotes, which features four main tracks: Embedded Hardware, Embedded Software, Connected Devices and the Internet of Things (IoT), and the ESC Engineering Theatre. As usual, I’ve gone through the list of talks and composed my own little virtual schedule which ended up with sessions focusing on power management, IoT, and security, as well some optimization and drivers development talks among others, such as patents, and the origin of Gerber files. Wednesday 13 8:00 – 9:00 – Power Management in Embedded Systems by Colin Walls, Embedded Software Technologist, Mentor Graphics The importance of power management in today’s embedded designs has been steadily growing as an increasing number of battery powered devices are developed. In this session, we will discuss design considerations that should be made when starting a […]

Bringing a Better Port of MicroPython to ESP8266 (Crowdfunding)

MicroPython is an lightweight implementation of Python 3 that runs on ARM Cortex-M micro-controllers such as STM32 or Texas Instruments CC3200, and since ESP8266 is so popular, work has started to port MicroPython on the Tensilica Xtensa LX106 based WiFi SoC. The current ESP8266 port comes with some API callss specific to ESP8266, but is quite basic, uses the execution model provided by Espressif, requiring callbacks to process WiFi requests, and doesn’t include support for many of the chip’s interface such as SPI, nor support WiFi fully. That’s why Damien George, the project lead, has launched a Kickstarter campaign to help fund development of the port, aiming to raise at least 6000 GBP (~$8,500 US). The goal is to develop “proper” Berkeley sockets for MicroPython on the ESP8266, in order to provide a true Python socket API to make development easier, optimize RAM usage, and implement the missing parts on […]
