Sync display_driver.py from lvgl-bindings 45be184 (frame-gate cap) - #24
Merged

Conversation
lvgl-bindings#19: after a slow LVGL pass, the frame gate holds for at most max_yield_ms (default 100; event_loop(max_yield_ms=...) or on the instance). Passes up to 100 ms hold exactly as before, so lvgl-bindings#15's case is unchanged; a long pass -- typically application work run from LVGL timers -- no longer leaves the thread idle for as long again. It also brings d5f3d34 (lvgl-bindings#15), which this repo's pin predated: after a slow pass the gate holds for as long as the pass took, so a slow frame lowers the frame rate instead of taking the application's thread. Made with scripts/sync_from_lvgl_bindings.sh --ref 45be1848ed73057891aff7ccd477ce563a56939a.

display_driver.pyfrom lvgl-bindings45be184(lvgl-bindings#19) with this repo'sscripts/sync_from_lvgl_bindings.sh --ref 45be1848ed73057891aff7ccd477ce563a56939a. The pin inLVGL_BINDINGS_COMMITmoves with it. Between the old pin and45be184nothing changed in the generated binding,lv_conf.hor the LVGL submodule: onlypython/display_driver.py.What changes: after a slow LVGL pass,
event_loop's frame gate holds for at mostmax_yield_ms(default 100 ms, settable withevent_loop(max_yield_ms=...)or on the instance). Passes up to 100 ms hold exactly as before. A long pass, which in practice is application work run from LVGL timers, no longer leaves the thread idle for as long again.Measured in lvgl-bindings#19:
sleep_ms(5)stays at 5.0 ms, and the application loop gets the same share of the thread as with display_driver: let appdev.App own the lifecycle #15's fix.This repo's pin predated lvgl-bindings#15 (
d5f3d34), so that fix comes along too.
