Hello,
according to https://docs.lvgl.io/latest/en/html/porting/indev.html, I’m trying to install a feedback-callback which gives me a “Click” whenever the touchpad is touched:
/* initialize input device */
lv_indev_drv_init (&touch_indev_drv);
touch_indev_drv.type = LV_INDEV_TYPE_POINTER;
touch_indev_drv.read_cb = LVGL_Touch_Read_Callback;
touch_indev_drv.feedback_cb = audio_play_click;
touch_indev = lv_indev_drv_register (&touch_indev_drv);
But the callback is never called at all.
What am I missing here?
