Together with Pulseview, the ESP32 can be turned into a Logic Analyzer. I demonstrated how to build a simple SUMP logic analyzer with [my ‘logic-analyzer’ library] in my last blog, (https://github.com/pschatzmann/logic-analyzer). Of cause the described sketch is also working for the ESP32. But we can do better! Here is an Read more…
Recently, when I started to research the topic of Logic Analyzers, I found the incredible PulseView Project. However, I did not want to invest in additional hardware but just use one of my favorite microprocessors (ESP32, Raspberry Pico) as capturing device. There are quite a few logic analyzer projects with Read more…
Today I published the new 1.2.0 Release of my ESP32-A2DP Library. It contains the following improvements: Metadata support with the help of a callback function – Thanks to JohnyMielony AVRC command support thanks to PeterPark Improved init_bluetooth checks, in case bluedroid was already initialized elsewhere – Thanks to Antonis Katzourakis Read more…
I finally could tick off the final to-do for my Pico-Arduino project: It is not necessary any more to install the project in advance. The project can now be treated as library and you can just pull it automatically from github with the help e.g. of a cmake fetchcontent. Here Read more…
Microcontrollers are not suitable to develop and train machine learning models. The resources are just not sufficient for this, but it is possible to use and deploy pre-trained models! I have added a simplified Tensorflow hallo world example where the model has been trained on the sin function, to my Read more…
Most Arduino based Drone projects are optimized for AVR processors by writing directly to registers and use other AVR specific functionality (e.g. timers interrupts). The multiwii project is a good example of this and it would take quite some effort to convert it to be compatible with the Pico, because Read more…
I am quite enthusiastic about the new Raspberry Pico. However I find the C SDK not very friendly and I prefer to have something as simple as the Arduino API. I did not want to wait for the official Arduino support – so I started my own project. PWM in Read more…

I had too many micro controllers and sensors and I wanted to have simple box where I can put them and easily find my modules again. This is the perfect use case for 3D printing: Of cause the modules and micro controllers come in different sizes so the design needed Read more…
