Arduino for STM32

Hi,

I had to redefine LED_BUILTIN for my Blue Pill sketch:

#undef LED_BUILTIN
#define LED_BUILTIN PC13

Is it merely a bug, or some obscure configuration lost? Tools settings of Arduino IDE 2.2.1 for the Blinky certainly got lost; I restored them manually. Or I think I did

No change, always defined on PC13:

Guess you don't select the correct target and use the blackpill one.

Exactly. Thanks! It's kinda easy to mix them up...
