"error compiling for board Teensy LC" when trying to use ILI9341 example sketches
Hello,
I'm getting the Teensy "error compiling" message when trying to use any of the example sketches for the ILI9341 touchscreen. I'm not sure if there is something in the code that is specific for an arduino nano, or if something is wrong with my libraries. I am getting error messages about a "KINETISK_SPIO" that I don't understand. Any help would be greatly appreciated!
Here is the error message:
And here is the code

Check out the links above for our tutorials and wiring diagrams
These displays use SPI to communicate, 4 or 5 pins are required to
interface (RST is optional)
