Serial Communication st32 Arduino IDE.

[Alec1of1]

What have you done with IDE no serial communications allowed on STM32 boards? F0 F1 F3 F4 series. No one USB-to-TTL adaptor works after compiling the code. IDE of arduino became absolute, totally useless, Congratulations on a well-done job! Need to move to CUBE or Platformio.

Arduino IDE 1.x is no more supported since Arduino specification changes.
Use Arduino IDE 2 instead.
