UART is not RS232 #4

Closed dazwin closed 1 year ago

It should not be said that MCUs (including the STM32) can transmit/receive data using RS232, which is an electrical specification as well as a communication protocol. You could damage the MCU if you try connecting it directly to RS-232 equipment.

Nice background read - thanks!
