Hello!!
I have problem witch initiation USART in STM32 microcontroler. I use standard KEIL configuration file to setup USART. After configuration (I stop program witch while(1) function) but I receive in Windows Terminal one unexpected sign. I can't eliminate this problem...
It is not at all unusual for any system to generate the odd "glitch" on startups - with a serial connection, that may well show up as an odd character...
