RE: Error in calling lv_tick_inc function from LVGL in NCS2.5.0

Hi,

I've been stuck on this for about 2 days and did differently from this approach. I put everything as an example building it on top of Zephyr's lvgl example and left it public on my GitHub repository in case others might use it.

Hi,

I started with the lvgl sample, and the copied your code, and also updated the configs like you have. I am not using the "common.h" and therefore removed that functionality. Also, I am using nrf52840 and adafruit tft shield.

I could see what you mean. It would generate error and ask if we wanted to use lv_tick_set() function instead of lv_tick_inc() function. I opened the file containing lv_tick_set. It is LV_HAL_TICK.C.

The definition of lv_tick_inc() function lies under the if-condition requiring LV_TICK_CUSTOM to be set as 0. Therefore, this function was not actually defined (as LV_TICK_CUSTOM is 1)
