Hello,
I want to communicate an STM32 with a Raspberry Pi using UART. But I wonder if I need Line Drivers/Receivers like SP232E between microcontrollers. I mean, If I use RS232, would it make communication more reliable? Or does it depend on the distance between MCUs? What exactly can define if I should use drivers or simply connect directly RX and TX pins?
