How-to
1

What MCU/Processor/Board and compiler are you using?

IMXRT117xDVMAA

What LVGL version are you using?

V8.3.5

@file lv_conf.h
/Input device read period in milliseconds/
#define LV_INDEV_DEF_READ_PERIOD 20 /[ms]/

The input device read cycle set to 20ms, but the read cycle is lengthened when you drag the slider.
I need a stable read cycle, how do I do that???

When dragging the slider, the position of the handle updates slowly.
