.platformio with espidf framework compability

[DrZlo13]

Hello, i noticed that commit says this project have compability with .platformio build system, but i dont have any luck to compile that.

For now i have bunch of "undefined reference to `lv_something'" and i don't know how to fix any of those things.

Hi @DrZlo13, I don't personally use Platformio but hopefully @davidjade can help us out. On the meantime, could you attach a text file with the output you are getting to check what functions are not being defined?

Hi,

I've just tried it with our lv_platformio project and I added these lines to plaformio.ini:

[env:esp32]
platform = espressif32
framework = espidf
board = esp-wrover-kit

Changed the efault environment to default_envs = esp32

And modified main.c like this:

#include "lvgl.h"
// #include "driver.h"

#include "demo.h"

int app_main(void)
{
	lv_init();

	// hw_init();

	demo_create();

	// hw_loop();
  return 0;
}

And it compiled but I can't test it on hardware now. 🙁

Any feedback @DrZlo13?

This issue or pull request has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[C47D]

Will add the steps @kisvegabor took to make it work with platformio into the README. Then I will close this issue as there wasn't any feedback.

[kisvegabor]

To the README of this repo or lv_platformio?

[C47D]

I was thinking on this repo README, what do you think?

[kisvegabor]

I'm ok with adding this to the README here.
We can say to use lv_platformio repos and modify its platforimio.ini file.
