Teensy Compilation Error

[adstep]

When I compile with MCU=at90usb1286 I see the following error:

 [GCC]     : Compiling C file "Joystick.c"

It compiles fine with MCU=atmega16u2. Anyone else get this problem before?

The at90usb1286 support is from the original project. You'll need to consult the datasheet for that MCU in order to rewrite the serial receive code, as the registers are different.

I assume this means Teensy 3.6 is also not supported?

[wchill]

Teensy 3.6 doesn't use an AVR core, it's running an ARM Cortex M4. So everything is completely different for that.

[parkerlreed]

Yeah figured. Would be interesting as the 3.6 also has USB host so you could make it into a converter as well.

Thanks.
