Hi,
It’s excited to see the development of the LVGL moving forward so quickly, however it’s a pity that there’s still no examples for MicroPython for V7, any plans? I remember seeing somewhere that the V8 is soon to be released, any timeline? Just don’t leave us MicroPython users behind! 
Hi @dukeduck!
Micropython is supported on v7 and I’m planning to keep supporting it on v8.
There is an effort led by @uraich to create many Micropython examples for LVGL v7 and add them to the official LVGL docs.
See:
Also, the examples under the micropython binding examples directory are all compatible with v7.
If you have any specific questions, you are welcome to send them in the forum!
Thanks @amirgon! Great to know! I didn’t realize that there were examples on github already - I only checked the official docs.
I had worked with V6 and loved it a lot! Now I plan to start my new project with V7.
Keep the good work up!
Cheers,
Kaiyuan
Hi,
While the examples Amir pointed you to, are ports from C to Python of the examples in the lv_examples repository, I am about to port further examples which I upload to https://github.com/uraich/lv_mpy_examples.
For the moment there are 4 examples which I want to run on the LiliGo t-watch 2020. You find them in the folder t-watch_examples. Then I am working on demos that were originally written for the ST7735 driver, which I also port to lvgl. You find a graphics_demo under st7735_demos. All these examples also work on the lvgl unix port
Thanks for the effort @uraich. Kudo to you!
It will be great if the MicroPython examples will be added to https://docs.lvgl.io/ as well.
I had been working on an IoT course for the University of Cape Coast, Ghana, for which I ported the demos originally written for the ssd1351 controller to the st7735.
Now I try to port them to lv_micropython. These examples are quite a bit bigger and more evolved such that they don’t fit into lv_examples. If interested, here they are:
https://github.com/uraich/lv_mpy_examples/tree/main/st7735_demos
This is still “work in progress” and you may expect a few more demos being uploaded in the coming weeks.
Soon™. There are a few more changes to make which I haven’t had time for yet.
In some of the python examples, there’s a line of code: from lv_colors import lv_colors, but when I tried to import it in REPL, it threw an error: ImportError: no module named 'lv_colors'
How can I import lv_colors?
This paradigm confused me a bit as well when I was working with MicroPython on STM32. You have to copy this file to the MicroPython drive: https://github.com/lvgl/lv_binding_micropython/blob/master/lib/lv_colors.py
It would be great if the filesystem could be populated automatically with this but I’m not aware of a way to do that at the moment.
Thanks. I found that file as well and was scratching my head trying to figure out what went wrong when I compiled the firmware and missed it 
In this case it’s better to explicitly put a comment behind that line of import.
Frozen modules would do that trick.
Added in:
Perfect! Thanks!
This topic has been incredibly helpful to me as well, I was not aware of the examples in the GitHub repo and am looking forward to when they can be incorporated into the docs.
Going out on a limb here but has anyone converted the printer demo (from here: https://www.lvgl.io/demos ) to micropython?
Not that I know of.
If anyone is interested in working on that, it could be a very nice contribution!
I was feeling ambitious so have been giving it a go, running into an issue though.
Going through the c code there are many uses of LV_EVENT_CB_DECLARE and I am not sure how to apply these in micropython (this could just be lack of c knowledge). Any pointers on how to do this?
I know, there are a few demos I have not ported and the printer demo is one of them.
LV_EVENT_CB_DECLARE are just type declarations in C and since in Python you do not declare types …
Have a look at the btn examples to see how to implement callbacks
Thank you I will tets that out, I am trying to test out in the emulator but running into the issue of using images.
Does anyone know how to use images / image paths in the emultaor?
Which emulator: the Unix port or the online JavaScript port?
