Arduino for STM32

Posted: **Tue May 26, 2020 2:43 am**

Hello,

I post here today to ask you for help, I need to know how Arduino IDE uses polling (serial.available) I search and find the code but I do not understand how is adapt on a STM32 , I would like to use polling on an STM with CubeMX so use a command like serial.available().

Thank you for your help !

Usually it doesnt use polling. Serial.available returns amount of unread data in the rx buffer. That buffer filled by reading serial with serial interrupt handler.

Actually, this is polling (the read buffer)

Code: Select all

  while (!Serial.available())
     ;
  Serial.print(timer);
}

The code exists, but I can't figure out how to modify it for usage on an STM32. I'd want to implement polling on an STM using CubeMX, but I'm not sure how to do so ().
