Resolved! EXTI interruption flags

Hi.I am having some issues trying to use the EXTI module, to implement interruption routines associated to ports.The problem is related to the behavior of STM32 microcontrollers with ports interruptions. In most microcontrollers (i.e. Texas Instrumen...

Resolved! If I want to control a relay via the TX of a UART do I just connect the appropriate STM32 pin to the relay? Or is there anything else I need to do (besides programming)?

I'm looking to use a ITS4200S-ME-P relay to switch a high voltage signal and would like to control that via a UART. Per the datasheet this relay, "can be switched on and off with standard logic ground related logic signal at pin IN."
