In this Blog I am giving a little bit of background on how the sampling of analog signals has been implemented in my Arduino audo-tools library. My initial approach was based on the Blog from Ivan Voras using timers and interrupts. But there is a much better way by using Read more…
Please note that a lot has changed since I published this Blog! Tought it might be possible to make this work again, you are advised to use the current API with this updated example! The processing of files with the help of the ESP8266Audio is a little bit more involved. Read more…
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 a few questions on how to do this with files, microphones and I2S 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…

But we can do better: Here is an first version of an improved Pico implementation which uses both Read more…
