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

OLIMEX-STM32-H103

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.

 

BurgasConf is this Saturday 30th of June (of course in Burgas) looking forward to see you there

BourgasConf

BurgasConf is part of IT Tour – traveling IT events organized with the help of the local Burgas hacker space BurgasLab.

This Saturday it will start at 10.00 in Flora Expo Center.

Usually IT tour is focused more on Software than on Hardware, but this time we will try to change it a bit with Hardware related talk about the Flash memories.

These who come to the talk will learn about who invented the Flash memories, who are the major players and what are the trends. How the different Flash memories work, what we should know about how they wear and what precautions to take to minimize this, also are there security risks involved with their use.

We will not go in deep technical details, but enough to people learn what Flash memory is best for their application.

So looking forward to see you there!

Arduino Day 2018 in Plovdiv


arduino

Arduino Day is on 12th of May and celebrating at near 500 locations all around the world.

TuxCon and Smarty Kids foundation are participating in this initiative and organize event in Plovdiv in Grand center from 15.00 to 17.30.

The event is free and anyone can participate and learn how to program ESP8266-EVB boards with Arduino and to control servo motors remotely.

The original Arduino map is wrong, so if you want to participate please do not go to Saedinenie but to Plovdiv 🙂

The room has limited seats so we advice you to register in advance. If there are more people interested the organizers are ready to do it again for all these who can’t manage to register on time.

TuxCon-Kitty the OSHW TuxCon 2017 conference badge soldering kit is in the web shop

TuxCon-Kitty

TuxCon 2017 conference was 3-4 of June in Plovdiv. Specially for the conference we made soldering kit badge, designed with KiCad and programmable with Arduino IDE.

TUXCON-KITTY-1

Here is how it looks assembled:

The project is hosted at GitHub. It’s good way to learn how to assembly SMT components and how to install, setup and program with Arduino IDE.

Do not hesitate to make pull request for your Arduino sketch if you manage to compose your own music with this board 🙂

 

TERES I Do It Yourself Open Source Hardware and Software Hacker’s friendly laptop is complete

teres

We are proud to announce that our TERES I laptop is complete. We have assembled units and now working on the software.

The building instructions are uploaded here and you can see that it’s pretty easy to build one yourself.

This weekend in Bruxell at FOSDEM we will have table in Hall AW where every one could touch and play with the very first built laptops.

All spare parts are uploaded at the web.

Hardware CAD files and Linux build scripts are on GitHub. TERES I is completely designed with KiCAD FOSS so everyone can download and learn, study, edit, modify.

Hardwarewise everything is OK and works, the software need some care to be completed, power supply management, Linux distribution, and few more details need attention, but we hope everything to be complete till Friday!
