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 this logic is distributed all over the place. I “adopted” the CodeDroneDIY project because I only needed to replace the MotorsSpeedControl.cpp with a implementation which 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 the Pico I was struggling quite a bit to have PWM working properly and the Pico PWM API is pretty nasty because you have to 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. The major weak spot of the Pico compared to the ESP32 is the missing Wifi and Bluetooth functionality. I finally managed to add examples for the HC05 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. So far this has been just a Toy Project, but with the addition of SPI, we can now take on some more complex Arduino projects. In order 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 act as USB host or as device. In this blog I will concentrate on the USB device functionality, because this is where the library shines. 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. So the question is, can we use any Standard Arduino Libraries with this and the answer is yes we can! We just need to use a little Read more…
