In one of my past Blogs I have described how to implement a simple tone generator using a Repeating Timer for the Raspberry Pico with the C++ SDK. This time I want to describe an approach which is a little bit more versatile: The Pico provides no built-in DAC and Read more…
Today I had a look under the hood of the Standard Arduino implementation for the Raspberry Pico. I was surprised that they did not base their work on the Pico API but they based their work on ARM Mbed. Here is a blink example using the Ticker from the Mbed 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…
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…

Introduction Most Microcontrollers have a built in Serial USB functionality that can not be changed (e.g. ESP32, ESP8266, Arduino Nano etc). Some Microcontrollers however allow to (re-)progam the USB functionality (e.g. Raspberry Pico, ESP32-S2, seeeduino xiao etc) and TinyUSB is the project of choice for this. A Microcontroller can either Read more…
