I've tried to load the Mazda firmware on to my CBT, and it locked up. I had to resort to the physical reset button on the board to regain access.
I can load in the standard CBT firmware using the Arduino IDE, but the Mazda will not compile. First three depreciated #import statements in MazdaWheelButton.h. If I change them to #include, I get a whole raft of errors.
Of course, I'm trying to connect to a 2016 Mazda MX-5, so this is important to me :) I'm a pretty lightweight programmer, so please be patient.
