In my Arduino ESP32-A2DP library I am providing some very simple examples that show how to transform the ESP32 into a A2DP source and transmit sound to a Bluetooth Sink (e.g. some Bluetooth Speakers). I had quite some questions on how to do this with files, microphones and I2S as Read more…
Together with Pulseview, the Raspberry Pico can be turned into a Logic Analyzer. I demonstrated how to build a simple SUMP logic analyzer with my Arduino logic-analyzer library in my last blogs. In this Blog, I demonstrate how to use the PIO which allows much higher capturing speeds. In theory Read more…
I have a first DRAFT version for the Pico PIO implementation of the PicoCapturePIO capturing class for my Arduino Logic Analyzer Library ready and started to run some tests. The Test Sketch is part of the project and can be found in the examples forlder. I was using a PWM Read more…
Together with Pulseview, the Raspberry Pico can be turned into a Logic Analyzer. I demonstrated how to build a simple SUMP logic analyzer with my Arduino logic-analyzer library in my last blog. But we can do better: Here is an first version of an improved Pico implementation which uses both Read more…
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…
