My understanding is that the enable pin you mention (ENRX/TX) is just routed to the ENRS485 pin (PB4) as long as the J17 jumper is connected, which I made sure it was. I don’t see any more references to ENRX/TX on the schematic, so I suppose there´s no other way to drive it directly, only via PB4.
So, all I would need to do is to set the PB4 high for receiving and low for sending, which I’m already doing, yet it doesn’t work. (I’ve also tried the opposite polarity just in case)
Am I wrong? Is there another pin I need to control, or do I need to configure the PB4 pin in some way in the project´s .ioc file?
