Hello Teensy people,
So I've got a T4 board that I've nigh filled to the brim with things. Nearly every pin is accounted for and I want to squeeze a little display on there last. In the future I'll pick something with better documentation, because I'm currently wondering how to hook it up.
It has pins GND/VCC, SCL, SDA, RES, DC and BLK. The lack of CS pin points to using the SPI_MODE3 option in the initializer. And there is some discussion about what minimal pins to use with the Adafruit variants, but I'm unsure what to do with this information as it doesn't seem to line up with what I have here.
This project (whilst not a teensy) has the same display, but SDA SCL pins etc. don't match with this very enticing CD/DC/RST setup. Are these simply different names for the same pins?
Thank you kindly for any insights into pin mappings or optimal performance for these little displays.

Code:
ST7789_t3 tft = ST7789_t3(TFT_CS, TFT_DC, TFT_RST); // this three pin connection seems incredibly useful, but I think it may not be possibleThank you kindly for any insights into pin mappings or optimal performance for these little displays.
