Move from u8g2 library to lvgl library for OLED display.

[gautam-dev-maker]

lvgl library seems more industry standard than u8g2 library. So we should rewrite all our OLED wrappers in lvgl library.

@Jamm02 @ChinmayLonkar @Sidshx has anyone been assigned to take up this task? or should I assign one for this?

[Sidshx]

Picked up the task. @Premraj02 will be accompanying me.

[gautam-dev-maker]

@Sidshx any updates on the issue?

[Sidshx]

Started referring resources on u8g2 and lvgl library and getting acquainted with the Wall-E codebase. Will be sharing an implemented work update soon.

@Sidshx updates?

@Sidshx updates?

Imported and implemented the lvgl library, along with lvgl driver support for the esp-32. Configuration and hardware testing to be done at SRA tomorrow. Working with @Ayush-Kaura

the logo can still be made a bit smaller to fit in OLED

@Ayush-Kaura With next update also issue the draft PR for review.

Using LVGL v8.3, master branch had some api changes
Files Modified: lv_conf.h for setting lvgl related options inside LVGL folder, lvgl_helpers.c driver for ssd1306, oled.c and main.c inside src, CMakeLists
Link will open draft pr after some of below work done: https://github.com/Ayush-Kaura/sra-board-component/tree/lvgl_port

To-Do

• lvgl requires functions like lv_task_handler, lv_tick_inc
• overall functions structure in oled.c (function parameters to be passed)
• i2cdevlib for mpu and lvgl

We are already using i2devlib. Just check the source code. :)

@Ayush-Kaura I don't see the code used to display all these things in the fork.

Sorry I meant using the same for lvgl driver as done for u8g2 previously, so that we can use both mpu and oled together.

As discussed do the following changes:

• Use GLOB in CMakeLists.txt to add source files of LVGL instead of manually adding name of all files
• use i2c_dev_lib and test with MPU6050 and OLED both together
