    Communicating between boards

    Hi, I have three (soon to be four) Teensy 3.5 boards configured as XPlane FlightSim devices, and I need someone to point me in the right direction to talk between the boards. They all show up in Arduino as the same Teensy port number which I've already posted about, so I'm at a loss as to how to...

    Need to understand Teensy ports.

    Hi, I don't really know how to correctly explain this or the right question(s) to ask. Hopefully, there's someone smarter than me who knows what I'm trying to figure out. I am having issues getting my different XPlane controllers to play nice together. There seems to be a COM port conflict...

When I plug it in, the computer chirps as expected, but Arduino doesn't see it and nothing gets added in Device Manager under Human Interface Devices. In...

    Hi, On my Teensy 3.5, I have a rotary potentiometer that includes a switch. I can tell if the switch is being turned on or off by checking Bounce.risingEdge() and Bounce.fallingEdge(). I can also set my volume based on the potentiometer output by checking analogRead(A1). What I can't figure out...

    Can't change 7 segment display

    I can get the MAX7219 to initially put numbers on the 7 seg digits, but if I change any value it either turns completely off or completely on (all lights lit 8.8.8.8.8. I tried to make a timer that counts seconds, but it turned off, then on, then off, etc. every second. There must be something...

    XPlane DataRefs

    Hi, I am using a Teensy 3.5 to build a box to control everything on XPlane's GNS430/530, and I have run into a couple of snags. First, I have searched all over the web looking for how to detect that the GNS430 MSG indicator is on. I have found how to send the MSG button press from my Teensy...
