Hi. I'm testing a new board with a STM32F091rctx micro, where the 485 bus is bring up using these pinouts:

PB5 (Enable)

PD2 (Rx)

PC12 (Tx)

Is the Enable signal moved by the Hal libraries or have I to move it?
Using an oscilloscope I see something coming out when I send something but I never receive nothing.
Have I to have a differt approach whit 485 bus than the serial ports?
