On Friday I was receiving my Raspberry PI Pico and I had the opportunity to play around with it. Actually most of the time I spent reading the Manuals… The conclusion: interesting – but a little bit too complicated to use – So I was quite happy to read that Read more
I really wanted to have an interactive Jupyter environemnt in which I could play around with Arduino commands and when I discovered that Arduino provides a good starting point with their ArduinoCore-API I started to draft this prototype. I am using xeus-cling as a runtime environment to simulate an Arduino Read more
Hardware I was receiving my ordered SD module but I was struggling a bit to connect it to my ESP32 via the SPI interface. I double checked the connections to make sure that I was using the right SPI pins, no change! I reformatted the SD drive again using FAT32. Read more
For one of my current projects I had a closer look into the HTTP Protocol. Usually you might use a separate library for doing http calls from Arduino (e.g. with an ESP32) but if you are low on memory, you might get away without this by just using the WiFiClient: Read more
When I was in University 40 years ago, I was a big fan of C++. However I never had the need to do any projects in this language so far. I did plenty of work in ABAP, Java and later on enjoyed the relaxed approach on the usage of semicolons Read more
I had the need to pass some callback functions to some of my generic C++ Arduino classes. So I was asking myself if we can use Lambdas in Arduino. Here is a small test sketch, to verify this. #include “TestLambda.h” void setup() { auto f1 = [](int number) { Serial.println(number); Read more
I was looking for a Arduino library which would allow me to access remote files on a Linux server. Unfortunately I did not find anything that I liked. So I came up with my own solution which is based on FTP. The FTP protocol is one of oldest communication protocols: Read more
I made the Synthesis ToolKit (SKT) available as Arduino Library. The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with Read more
Overview The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. You can find further information in the original Readme of the STK Project Like many other sound libraries it originates from an University (Princeton) Read more
