I had the issue that the 24 bit output via A2DP was not working, but the corresponding 32 bit example was just working fine. So I decided to double check the I2S output with the help of a logical analyzer. Checking 16 bits First I was double checking how the 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…
