Hi,
I a same problem
Could you tell me the step of build ?
thank you
Hello PAT,
if you want people to be able to help you, you should include all relevant informations like:
- OS you´re working with
- your installed Python version
- which version of micropython you downloaded
- which version of LVGL
- the platform and board you´re compiling for
… and the error you encounter, which steps you followed that lead to this error
Hi,
I did this with no error (board = PICO, operating system = Raspbian)
git clone https://github.com/lvgl/lv_micropython.gitcd lv_micropythongit submodule update --init --recursive lib/lv_bindingsmake -C ports/rp2 BOARD=PICO submodulesmake -j -C mpy-crossmake -j -C ports/rp2 BOARD=PICO USER_C_MODULES=../../lib/lv_bindings/bindings.cmake
MicroPython v1.20.0-700-g841ece132-dirty on 2024-01-22; Raspberry Pi Pico with RP2040
Type "help()" for more information.
>>> import lvgl as lv
lv.init()
>>> disp_drv = lv.disp_drv_t() # This line fails
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'disp_drv_t'

Thank you
Hello!
There are a lot of breaking changes (refactors, renamings, drawing architecture change) in v9 compared to v8, so many objects/structs are renamed.
For example in v9 there is no more lv.disp_drv_t, but lv.display_t. But please check documentation.
The actual (2024-01-23) status of LVGL - MicroPython binding (lv_micropython repo):
masterbranch: an “old” version of MicroPython v1.20 and LVGL v9-dev → this is unstable, and will be updated soon fromfeat/multi-instancebranchfeat/multi-instancebranch: it contains the latest LVGL v9 version (still MicroPython v1.20), and this will be merged tomasterbranch (after PICO CI build is fixed)release/v8branch: it contains the previous LVGL 8.3 version, so if you want to use it, checkout this branch: GitHub - lvgl/lv_micropython at release/v8. Please use the LVGL 8.3 documentation for it: Welcome to the documentation of LVGL! — LVGL documentation
thank you for your reply
I wanted to try the release/v8 but the construction failed.
git clone --single-branch --branch release/v8 https://github.com/lvgl/lv_micropython.git

Thank you
UPDATE - 2024-01-24
master branch is updated from feat/multi-instance branch, so it contains now LVGL v9 (release version).
For better image rendering performance please set LV_CACHE_DEF_SIZE and LV_IMAGE_HEADER_CACHE_DEF_CNT configs in lv_conf.h for your device’s available memory, and build new firmware.
I’ve tested Unix, and ESP32 ports, but other ports (including RP2 (PICO) board) not yet.
There can still be some bugs and issues, so please report those here: Issues · lvgl/lv_binding_micropython · GitHub
Hi !
Perfect, Build success 100%.
I have 2 questions
- Are there any simple, ready-to-use examples for v9 ?
- Are the display drivers included in the build or do they have to be added to the flash ?
Thank you
update : unfortunately I still have problems

Hi!
- You can check LVGL documentation (you can figure out the MicroPython code from C code, but later we will add again MicroPython examples to documenation), or see LVGL-MicroPython binding examples
- For some ports and boards drivers are added (frozen drivers), for some not, so you have to add yourself.
Your issue with disp_create:
it’s a bug in LVGL binding, I will fix it.
UPDATE:
bug fixed, please pull latest of lv_micropython repo.
(PS: I’m also waiting my ordered RP Pico, so when it has arrived, I will test MP with it and fix all the remaining bugs)
thank you very much for your responsiveness
I’ll have to wait, I lack the skill to find the problem.
The screen changes state but nothing is displayed.

Thank you
Thx for sending your code.
I can test RP Pico tomorrow afternoon, so will let you know the result.
Thank you very much for your support
Hello @PAT ,
There was a bug in st77xx.py generic driver, that is fixed in lv_micropython repo.
Please pull and build again, and test it.
I have also tested RP Pico with ILI9341, and it works now.

Hello @PGNet
Thank you very much, it’s work ! Can I ask you 2 more questions ?
-
What’s missing in my code because every time I make a change I have to unplug the USB from my PICO (I use Thonny IDE) ?
-
How do I increase the size of the text in countdown_label.set_text(“00h00m00s”) ?

Hi!
- There seems to be a bug in MicroPython or LVGL, that soft-reset does not clear everything. I started to use
mpremote resetafter every file upload. - Increasing text size => change font.
In LVGL we have the standard binary font engine, and an optional tinyttf engine. In MicroPython binding the tinyttf is disabled.
Read more about font loading: Fonts — LVGL documentation
File system drivers needs to be registered to load dynamically fonts.
Copy fs_driver.py file to Pico.
Example of loading font:
font = lv.binfont_create("A:KeepCalmMedium-32.font")
label2 = lv.label(screen)
label2.align(lv.ALIGN.TOP_MID, 0, 10)
label2.set_style_text_color(lv.color_black(), 0)
label2.set_style_text_font(font, 0)
label2.set_text("Hello World!")
(the full example: Raspberry Pi Pico W with ILI9341 display - LVGL v9 example · GitHub )
Convert TTF font to LVGL binary font:
Hello,
Thanks to you I now have all the tools I need to explore LVGL.
I tested the :
button events
timers
FT6x36 for my display
I still have to find a 7seg font for my countdown and put the values of my ADC (multiplexed) in the textarea.
I’m sharing the code in case it helps anyone.

Hello
Wouah !!! 
Yes, I’d like to
OK I will have to do some work with it to make it work with LVGL v9.0. That is not a font, It is rendered real time. In LVGL v9.0 the canvas widget (which is what is being used for the rendering) has changed, I need to update the code to work with that. It is written for MicroPython which is something I know you are using.
For some reason I think there was a modification in the canvas widget that is going to make it challenging to render. I believe the ability to render polygons has been removed… BOOOOOO!!!.. This was done in favor of using ThorVG but the problem is ThorVG is not going to run on MicroPython to the point of exposing the API to be able to render. This is because ThorVG is written in C++ and the binding build code is not able to programmatically read the code to write the C code needed to expose the ThorVG API.
I am using polygons (triangles) for the ends of the segments. Now I am going to need to use triangle math to calculate the number of lines that will be needed to do the fill. Not too big of a deal, just more work to make it run with LVGL V9.
Hello,
Thanks in advance for your help. I’ve read the other discussions and I understand that we’ll have a stub file for pycharm and an LVGL that’s easy to integrate into micropython.
Thanks again for your work and for sharing your experience with us.
