Connect SSD 1309 OLED to Teensy 4.1 with SPI (MOS1 and SCK1)

[DragonSF]

Which library would work with this configuration? I tried Adafruit,Sparkfun and U8X8 libraries. I got some white noise from Sparkfun, so the device is working, but other libraries where jsut dark. Please direct me to the right track.
BTW I tried that also with the MOS0 and SCK0 pins.

Or if possible, a library, which supports I2C.

I think the thread linked below might help

Are the SSD1306 and 1309 driver really the same? I tried all 1306 libraries to no avail.

Thanks, got it working so far on a Teensy 4.0 with the SSD1306Ascii library.
