Setup OLIMEXINO-STM32 to work with Arduino IDE


Arduino IDE support Cortex-M ARM architecture and although STM32 is not “officially” included has all the resources to add support for STM32 boards in Arduino.

This forum post explains what should be done step by step to setup and use OLIMEXINO-STM32 board with Arduino IDE.

Programming ESP8266-EVB with microPython tutorial


Our Belgium distributor MCHobby made nice tutorial about how to program ESP8266-EVB board with microPython.

The tutorial is available also in French.

Nice tutorial for writing and debugging plain C on ARM Cortex-M3 STM32F103


Jacob Mossberg wrote nice tutorial how to program in C ARM Cortex-M3 with GCC and how to debug it with GDB and OpenOCD.

We like very much the hardware he is using 🙂 STM32-H103 and ARM-USB-OCD-H.


A20-OLinuXino-MICRO project – How to set up a raid 1 filesystem


Flayol Frédéric submitted on our project page link to his interesting project, he setup Raid 1 file system with two USB Flash drives.

There are also many other interesting projects on his blog!

Do button for IFTTT with ESP8266-EVB now you have endless opportunities to make receipts with the IFTTT tools


IFTTT is a web platform that facilitates connections between other big platforms under the form of recipes giving a great degree of flexibility in creating mashups. You can interact with almost  every social platform on the web like Facebook, Twitter, Instagram etc. For this purpose you make receipts like: If I get e-mail with picture on my Gmail account store the picture in my Dropbox and share it on Twitter, or etc.

Just a few days ago IFTTT launched a channel for makers.This was a highly awaited feature since until now it was impossible to connect prototypes to the recipes and only a few approved devices were available from large producers that were accepted in the platform. The Maker channel changes all that. It allows both making web requests to the channel to send events to other platforms from devices and from other platforms to the devices.

Constantin Craciun almost immediately add “DO” button with ESP8266-EVB and here is his tutorial.

You can see on this video how he uses ESP8266 to switch ON and OFF lamp via his phone:

Now you can think of endless apps for this DO button, like sending SMS “I’m home” to parents phones when the kid arrive from school and press the button.

Or button at the reception desk of hotel which send message to taxi company “go to hotel xxx to pickup customer”, etc. etc.

We are working on the small cloud broker for our ESP8266 IoT Firmware, and this IFTTT API will be definitely among the first implemented!

ESP8266-EVB support for JTAG development with flash load, breakpoints, disassembly, step debugging in Visual Studio C/C++


Ivan Shcherbakov @SysProgs shared interesting article. He wrote support for ESP8266-EVB to VisualGDB Visual Studio plugin for embedded software development in C/C++.

With this plugin you can use JTAG to debug code in ESP8266, also to set breakpoints, view the disassembled code etc. This adds new level for professional developing using ESP8266.
