V1.0.4 is released

kisvegabor · March 11, 2022, 7:06pm

Hi guys,

Here is a new patch release with the following fixes:

Fix typo in the “Ignore layout” flag
Fix error message when the trial period is over
Fix the missing option setting in the exported code of Roller and Checkbox
Fix the missing exported code for the Chart
Fix overwriting the content of ui_events.c on export
Include lvgl.h in ui.h in a more flexible way
In the exported code check if the color settings are correct
Add “ui_” prefix to the names of the widget in the exported py files to avoid conflict with reserved words

Thank you very much for the great feedback and reports! You help a lot a to make SLS better!

Unfortunately, the MacOS support and life-time license option needed to be shifted to v1.0.5.

“Include lvgl.h in ui.h in a more flexible way” worries me as my code no longer compiles now I have switched to 1.0.4

I now get:

In file included from ui/ui.h:14,
from ui/ui.c:6:
/home/pi/oven2/lvgl.h:25:10: fatal error: src/misc/lv_log.h: No such file or directory
25 | #include “src/misc/lv_log.h”
| ^~~~~~~~~~~~~~~~~~~

I have to say that I hate the way includes are used in lvgl.h I have had nightmares getting LVGL to build and play happy with my own code. I now have a working source tree and am dreading having to upgrade to a newer version of LVGL when it is required by a new release of SLS

Do you use LVGL as it is or have you modified its directory structure?

AndyFraser · March 12, 2022, 1:40pm

I don’t think the directory structure has been modified. Here is the source directory structure.

I think this discussion should really be in its own thread but for now I need to understand the directory structure required by LVGL.

In the root of my source directory I have the lvgl directory and the lv_drivers directory.
In my makefile I set LVGL_DIR ?= ${shell pwd} which seems wrong as this is not the lvgl directory but the root directory.

I include the lvgl makefiles into my makefile thus:

include $(LVGL_DIR)/lvgl/lvgl.mk
include $(LVGL_DIR)/lv_drivers/lv_drivers.mk

This gives me the error:

In file included from ui/ui_helpers.h:10,
from ui/ui_helpers.c:6:
/home/pi/oven/lvgl.h:25:10: fatal error: src/misc/lv_log.h: No such file or directory
25 | #include “src/misc/lv_log.h”
| ^~~~~~~~~~~~~~~~~~~

If I change LVGL_DIR to LVGL_DIR ?= ${shell pwd}/lvgl and change the includes:

include $(LVGL_DIR)/lvgl.mk
include lv_drivers/lv_drivers.mk

I then get:

/home/pi/oven/lvgl/lvgl.mk:8: /home/pi/oven/lvgl/lvgl/src/widgets/lv_widgets.mk: No such file or directory
make: *** No rule to make target ‘/home/pi/oven/lvgl/lvgl/src/widgets/lv_widgets.mk’. Stop.

This seems to be related to how the lvgl makefile is defined:

include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/extra/extra.mk
include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/core/lv_core.mk
include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/draw/lv_draw.mk
include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/font/lv_font.mk
include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/gpu/lv_gpu.mk
include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/hal/lv_hal.mk
include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/misc/lv_misc.mk
include $(LVGL_DIR)/$(LVGL_DIR_NAME)/src/widgets/lv_widgets.mk

Why do you use LVGL_DIR and LVGL_DIR_NAME ?!

The name LVGL_DIR is really no intuitive. My intention with that was “the directory where lvgl is”. Sorry for the confusion.

So LVGL_DIR ?= ${shell pwd} is correct.

The root of the problem is that you have lvgl.h out of the lvgl folder. Why is that?

AndyFraser · March 16, 2022, 10:47pm

I think it was because I have having problems with code not being able to find lvgl.h and I could only make it work if I moved lvgl.h into that top level directory

Finally, does it work now if you move that lvgl.h file back to the lvgl folder?

AndyFraser · March 17, 2022, 9:16am

Yes, that all seems to work now

Many thanks for your help

Amazing! Thanks for the feedback.

Font manager issue. Try to create a custom font with the parameters like in the pic. attached. SLS generate error if the ‘Symbols’ field have the leading ‘-’ character.
