I really like to use the EmBitz IDE for STM32 projects. Unfortunately the current version (1.11) does not yet support STM32F7 devices. So I decided to write this guide how to get the "blink" example running for the...

I'm have recently finished my master thesis about FPGA implementations of various image fusion algorithms for fusing thermographic images and normal visual light images. Unfortunately thermographic cameras are quite expensive and complicated to handle so I thought of a way to create fake thermal...

For work we use an EtherCAT interface to connect our device. We use this interface by the german company Kunbus. To test everything we use SOEM (Simple Open EtherCAT Master) for the E...

We are currently tryring out several data visualization systems so we came accross redash. Because we are running mulitple web services on this server (gitlab, nextcloud and this blog) we decided to use a subdomai...

  • Hi, sorry for the long silence. I am currently working on a programming project involving a database where I need to check if user input matches a given date format (yyyy-mm-dd). As simple as it sounds it took me almost an hour to get the regular expression formated until the system finally did w...

    The oscillator circuit of an STM32 microcontroller is quite sensitive to wrongly chosen buffer capacitors or resitors. So I created an online calculator  to get the correct values. http://bastelhalde...

    My workbench needed a new light and the only way was to build my own. So I bought for a few bucks a 20W LED-chip in cold white and a suitable lens with ~70 degrees opening angle (which was more expensive than the LED, btw).

    The forward voltage of the LED is 34V @ 750mA. Since I also wanted...

    For those of you who don't want to visit your Teamspeak server only to see who ist online I wrote a litte C program which uses the telnet interface of the server to query the active clients. https://github.com/bkarl/ts3info

    In the previous article I posted some code to use the STM32 with a TLC5940. Now I improved the library a bit and put it on github. I suggest you use the code there, the documentation is far better....

    The TLC5940 is an LED driver which I use with my VFD clock project to power 4 RGB LEDs. I couldn't find any existing code for the STM32 so I decided to upload my code here in case anyone wants to use this component.

    As you may have noticed this block can be reached via two URLs. In the options panel Wordpress wants to know where it lives (Option_ WordPress Address_) and how it can be reached by regular visitors (Option Site Address). I have set up everything correctly but faced one problem when I t...

    The u8glib is a really nice library to use when you don't want to mess around with different diplay protocols or drawing routines. It is well-conceived and easy to use. Unfortunately there has been no port for STM32 microcontrollers so I tried to do...

    I had to shrink the first partition of our server recently but GParted and resize2fs had some problems doing it. There was always the error

    Please run 'e2fsck -f /dev/sda1' first.

    although I had checked all HDDs right before the attempt t...

    Prerequisites

    I recently got a Lattice XP2 Brevia development board to play around with FPGAs. This isn't the latest version of development boards you can get from Lattice but it will suit the needs of a beginner. I didn't find any simple tutorials dedicated to absolute beginners so I de...
