    TLC5940 led driver on Teensy 4.0

    Hello everyone, I'm trying to interface the TLC5940 to teensy 4.0.
    I used the pins shown on this page:

    https://www.pjrc.com/teensy/td_libs_Tlc5940.html

    where, for design reasons I used pin 9 instead of 7 for the SCLK signal.

    the pins to be reassigned with respect to the base pins of the sketches
    edit here:
    https://github.com/PaulStoffregen/Tl...y_KinetisK20.h

    but when I assemble the program the error is:

    #error "Unknown Chip!"

    I think Because the 4.0 processor is not listed in the library.

    Any suggest?

    Thanks a lot

    Exactly the same issue here. I'm trying to use with Teensy 4.1.

    I believe from another thread that the TLC5940 uses MCU specific code for speed.

    Fingers crossed Teensy 4.x is added!
