Using latest LVGL 9.2 has non working Dave2D

[FloHomi]

Hi,
I would like to use LVGL 9.2 with the RA8D1.
The LVGL version, used in this project, works somewhat okay. But some bugs and and missing features are leading to the wish to be able to ugrade the LVGL version.
The problem is, that I am not able to, due to massive amounts of errors that occure.
I simply replaced the LVGL folder with the 9.2 one. Is that wrong, and or does it need to be done way differently?
Thank you for your help!
Florian

Hi,

Please copy the errors here.

[FloHomi]

Yeah Sorry,
I managed to eliminate most of them by now. I think by updating the lv_config.h file.
It does still throw these errors:

I uncommented the lv_freertos_task_switch_in, lv_freertos_task_switch_out, lv_os_get_idle_percent in LVGL_Thread_entry.

and that left me with only the mutex one, which I do not understand enought...
after setting it for testing to NULL, it does not create any more errors. Not sure if the project will run thou.

pxMutex->xMutex = NULL;//xSemaphoreCreateRecursiveMutex();

Best regards

Oh I forgot, that I disabled #define LV_USE_DRAW_DAVE2D 1
If it is set to 1, it throws 450 errors, hard to tell what the start of them is...

some of them:
'lv_draw_dave2d_draw_letter_cb' undeclared (first use in this function) in lv_draw_dave2d_label.c
field 'base_unit' has incomplete type in lv_draw_dave2d.h
invalid use of incomplete typedef 'lv_draw_task_t' in lv_draw_dave2d.c

That was because I missed that in lv_config.h os needs to be NONE
#define LV_USE_OS LV_OS_NONE

Non the less, the dave 2d problem remains.

[kisvegabor]

I've just fixed these in master. Could you check if you still see any error? FreeRTOS should work too.

[FloHomi]

FreeRTOS now works! Thanks as always :)
#define LV_USE_DRAW_DAVE2D 1 still throws lots of errors. Maybe there is a missing settings in lv_config.h on my side?...
I set LV_USE_DRAW_SW 0 and DAVE2D 1 to test if that is a problem, but then I get:

133 | typedef lv_draw_sw_mask_radius_circle_dsc_t lv_draw_sw_mask_radius_circle_dsc_arr_t[LV_DRAW_SW_CIRCLE_CACHE_SIZE];

If both are enabled I get the 450 errors.

Did you try to enable Dave2D? because it is set to 0 in the current master.

I am sorry to not be able to solve it myself, but I am more of a HW guy and SW is not my strongest point, especially such big things as the LVGL code.

[kisvegabor]

Ah, sorry. Just pushed a fix.

FYI, In my test for some reason DAVE2D worked only in DIRCET_MODE.
