RE: Rotate st7789v display with LVGL

Is this configuration working for you? Any chance you can share the relevant device tree sections? Is there anything else you had to do? Are you using nrfConnect in VS Code (2.9.0+)?

Hello,

You need to define st7789v dispaly under SPI subnode.

mipi_dbi_st7789v {

pwctrl1-param = [a4 a1];

pvgam-param = [D0 04 0D 11 13 2B 3F 54 4C 18 0D 0B 1F 23];

nvgam-param = [D0 04 0C 11 13 2C 3F 44 51 2F 1F 1F 20 23];

ram-param = [00 F0];

rgb-param = [CD 08 14];

mipi-mode = <MIPI_DBI_MODE_SPI_4WIRE>;

};

Change to this, I can able to rotate display on 270 degrees.
