In the V9 there is no SPI property of ST7789.

Hello medelec35 ,
Thanks for your quick response. Unfortunately I am not finding any option for changing prescaler in the display property.

I am trying to use ST7789 1.3 inch LCD with Arduino nano with Flowcode 9. The written code changes background color in every second. But in practical the color changes very slowly from top to bottom (Slow motion), not instant. How can I set to change display instant? please help some one.
