Description

Hi,

Trying to run the i1c_oled example I get the following error when using LVGL v9.2.2
#error please disable LV_COLOR_DEPTH_1 for using monochromatic screen

And if I remove the LV_COLOR_DEPTH_1 config then the display uses 16-bit by default and doesn't work properly

Hello @abouatef, the LVGL port not support LV_COLOR_DEPTH_1 option with LVGL9. Instead of this, you can change color format to LV_COLOR_FORMAT_I1 here:

esp-bsp/components/esp_lvgl_port/examples/i2c_oled/main/i2c_oled_example_main.c

Line 129 in 056eb69

.color_format = LV_COLOR_FORMAT_RGB565,

The example should work with both color formats.

Please, don't forget remove these files and folder before build (if you compiled for LVGL8 before):

• build/
• managed_components/
• dependencies.lock
• sdkconfig
• sdkconfig.defaults
