Hello all - I've recently assembled my second Nybble, this time with a Raspberry Pi. I'm hoping to experiment with new behaviors and abilities. For now, I simply want to remotely connect to the RasPi and control Nybble through its terminal. But I'm having some trouble with the serial connection (I think). I did my best to follow the guide here: https://www.petoi.com/forum/hardware/how-to-setup-raspberry-pi-for-programming-nybble-without-ftdi-module but I may have made a mistake or two along the way. Any other advice or resources on getting Nybble up and running with a RasPi?
