Problem mangled screen Nano 33 BLE Sense & OLED 1,5" RGB (Wondershare alike)

[ovkarbudo]

Hello, Have a screen problem, please help me with a pinout or some help with code, maybe I must put #define SPI_HAS_TRANSACTIONS 1
and if so how and where, then modifiy my code, Thanks.
Dubravko
code is: Adafruit_1351_test
pins:
SCLK_PIN 13
MOSI_PIN 11
DC_PIN 9
CS_PIN 10
RST_PIN 8
or should I use left side of board other 2 pins: SDA & SCL and how hook to oled

  This is a example sketch demonstrating graphic drawing
  capabilities of the SSD1351 library for the 1.5" 
  and 1.27" 16-bit Color OLEDs with SSD1351 driver chip

  If you're using a 1.27" OLED, change SCREEN_HEIGHT to 96 instead of 128.

  These displays use SPI to communicate, 4 or 5 pins are required to  
  interface

Welcome to the forum.

Can you please modify your original post to ensure the source code is in a single box. It should look like this.

// Your example source code

You need three ' at the beginning and end in the edit window? When you click on this icon </> you get.

```
type or paste code here
```

This ensures we can get all the source code. Right now if you copy the code there are invisible characters that prevent successful compilation and parts might be missing.

Also add images to your post and not from external pages. People here tend to avoid downloading files from other sources. Datasheets links on manufacturer sites are OK.
