Hi
I accidentally connected the Panelolu (Panelolu2) cable the wrong way (one end wrong way and the other right way) and fried something. The Panelolu display shows some garbage and the computer can't connect Sanguinololu. It doesn't matter if I leave Panelolu unplugged, I still can't connect the printer. It does show up as /dev/ttyUSB0 so I would guess that FTDI chip is working. The Atmega1284P gets quite hot after a while so I'd guess it's broken. When I broke it, I could clearly smell something smoking, but I can't really say what it was.
Does anyone know what happens if Panelolu cable is connected the wrong way? Do I need to replace something other than Atmega or is it enough? How likely is it that I break the Atmega again if I only replace it and connect the Panelolu the right way this time? Also, can I test if the FTDI chip is really working by connecting TX and RX pins together and then writing and reading it on a computer?
Thank you for your answers.
