Wiki for Arduino STM32 etc

posted in: Arduino | 0

Because the thread on the Arduino forum is now huge, 50 + pages; by popular demand I’ve added a wiki to the GitHub repo which over time should help new users over the initial hurdles


Support for the Microduino STM32 board ( has been added – thanks to the work of Ian Hawthown

Some refactoring of the code has taken place, so that duplicate files from the variants folder(s) have been moved into the core – thanks to the work of Bob Cousins

Compile speed has been improved – thanks to the work of Bob Cousins, updating the compiler switches.

Some missing features to SPI have been added (by me) – Transactional SPI (new to 1.5.x) hasnt been finished, but works for the basic examples e.g. cardinfo.ino

A more general purpose way of selecting the board type and processor etc, plus compiler optimisation switching has been added – thanks to the work of Alexey (@HiddenPilot)

Various other bugs fixes have also been made.

Some bugs and issues still  exist. See the issues list on GitHub.


I have tested with the latest pre-released version of the IDE (1.6.rc1) and it appears to work OK, and compiles faster (this change seems related to the IDE not to BobC’s compiler switch change)


BTW. Sorry, but I’ve had to disable comments again, due to the massive amount of spam that this creates
