I have this board in my stock since some months and never taken time to play with it. As I’m starting some developments with STM32 it’s time to do it. I’ve tried to do some stuff using it at reception but even if there is some kind of Arduino mentions on the package the start is not as easy as on Arduino. Not regarding coding (it is more complicated but it is not the problem) but regarding the development environment. You need to use different tools and find yourself the way to use each of them. In my point of view ST would do a good thing simplify all this stuff. So in this post I’ll describe how to get started by creating your first led blink project. Hope it will save your time.
As I written this post for another target and it can be also useful for anyone, even if It is one more post on many of them, here are a couple of words about Meltdown and Spectre security issues. Read mode for details.
Following my previous post on bitcoin I’ve start mining with ASIC to continue playing the technology. I’ve started with a small USB ASIC providing 2GH/s. This is equivalent to 200 times the power of my Xeon server and it was really easy to install, running on a Raspberry Pi to simplify the usage.
This post details this experience and gives some advices for one wanted to experience mining.
I do not count the time I looked at Bitcoin in the past since about 2011-2012. Every time I started thinking about mining there was an investment to do (like GPU, then ASIC) and I never trust enough this money to make this investment. So as a consequence I never jump into this techno by the past, more than to understand how it works and learn.
Now Bitcoin in reaching some unexpected peaks ( > 15,000€ ) and it really looks like a bubble everyone is talking about, so as a mad man, I through it was the perfect time to start playing with this money. Trust me, as a guy who started investing in Internet technologies in 2001, you may never follow me on such decision !
Starting playing with this was an interesting learning opportunity, so this post will relate this experience and the different things I found in the bitcoin ecosystem.
This IoT class is an introduction to IoT and LPWAN, it has been made to be a 2x2h teaching session for engineer school students. This class has been given to I.S.I.M.A. school in Clermont-Ferrand in 2017. This class has been completed by 2 more hours on the backend part for IoT by Daniel Petisme. It has been followed by three industrial conferences.
The content of my class had the following slides (in French):
Introduce why IoT is a revolution compared to M2M and why service matter. Introduce the different phases of a connected object design and the involved technologies. Introduce the challenge, from the technical stand point to the business model considerations.
Sigfox just released publicly its Radio Signal Analyzer tool. This is a tool for the device & module maker to prepare the P1 certification : basically it checks the radio signal shape, power… and tell you if you are following the requirements.
The tool have to be used with the SIGFOX SDR dongle provided with the SNEK tool.
The software solution can be downloaded here : https://support.sigfox.com/downloads/sigfoxradiosignalanalyzer.iso
