Hello,
I ran into the same problem, with u8g2 libary on a Teensy4.1, but using SPI1 instead of there here mentionend Wire1 interface:
https://forum.pjrc.com/threads/67308-Should-Teensy-4-0-4-1-have-WIRE_INTERFACES_COUNT-defined
Could
#define SPI_INTERFACES_COUNT 4
be added in the same manner in cores/teensy4/pins_arduino.h ?
Thanks for all the great Teensy stuff!
Bob.
