ST7789 to RP2040 zero board

Other Hardware Displays

I want to connect these as stated in the title.

The problem is: the pin labeling is all over the place.

My display should be the same as:

At least the pins are called the same in the same order and count.

Now to my biggest issue. I found an example wiring everything sensible except for:
2040 Pin11(SPI RX but UART TX wut? Is this a MISO naming trnaslation weirdness? As connecting it to the SDA would form my understand make it a TX too) to SDA on the display module

Are my 2040 diagrams wrong? WHat's the logic behind this? The example also calls it softwarev SPI in the description despite the pins being labeled for hardware SPI:

(The black area is drilled out so the RP2040 can lay flat on the PCB, this is already tested and works.)

SPI RX is MISO and TX is MOSI
connect SPI TX to display SDA.
Don't mix SPI0 and SPI1 pins in same setup.
Also, RP2040 Connect is different board.

I don't know what you are reffering too, the controller is the same and I did not mix SPIs

With the only unclear thing being one line I guess I will just have the first attempt made like that and find out.

The fritzing part I use matches the pin out:

So what is that? Sda to Gpio11?
And Connect is different board even if one of the MCUs is the same.
