Hi, I have an old (9 years) Maple r5 complex program that was running well on Maple. I am trying to port the app to a "STM32_Smart" board (resembling the STM32 Blue Pill), but have some problems in compiling. The STM32 board runs the blink on USB OK. I suspect that the STM32 board installa...

I have a quite complex Maple r5 board and program that was designed and run by me some 9 years ago, when the Maple had some significant advantages over the Arduino (32bit, an extended Memory and its handling).
