I use a Teensy 3.5 with Teensyduino 1.44, and I am currently writing a driver for a MCP2517FD CAN controller. The INT pin of MCP2517FD is connected to pin #38. I have written that the SPI is using that pin with SPI1.usingInterrupt (38). But I think that this line has no effect.
I have examined the SPI.h file and I found the usingInterrupt function (from line 468). I think this function is valid for Teensy 3.1/3.2, but has not been updated for Teensy 3.5 / 3.6. Adding "|| n == 38" at the end of line 473 solved my issue (#38 is PTC11).
