Improvements for usage with ESP32-x #22

Closed brentru closed 1 year ago

brentru commented 1 year ago

This pull request adds fixes and improvements for using this library with ESP32-x:

Fix for hangs and freezes when using a sketch with LVGL and WiFi
- The LVGL task is now pinned to core1, leaving core0 for WiFi.
- NOTE: On the unicore ESP32-C3, it is pinned to the available core.
Fix for crashes when using LVGL with WiFi and TLS/SSL (mbedtls in esp32 core) by reducing memory usage
- LVGL_Glue on ESP32 uses ps_alloc() instead of malloc() to allocate memory from PSRAM. Some functions such as lv_tick_handler are also placed into PSRAM.

@PaintYourDragon This is ready for review. Do you think I should also include/rewrite the FunHouse ESP32-S2 example to use the lock/unlock functionality? I'm not sure I need to, that example doesn't utilize wifi.

Regarding FunHouse: although not using WiFi, it would be nice to have an example showing/documenting what the lock/unlock functions are for and how they’re used. Thx!

I'll add those today prior to pulling in.

@PaintYourDragon I've added an example, examples/hello_funhouse_wifi/hello_funhouse_wifi.ino, that shows how to use WiFi and LVGL together (using the modifications to LVGL_Glue proposed by this PR).

I'll merge when passing
