3-11-1_定时器(lv_timer)的用法是LVGL开源GUI零基础入门课程(韦东山·监制) 教程基于lvgl v8.2版本,课程适配多个平台、多款板子(Linux单片机GUI、littleVGL教程)的第40集视频,该合集共计55集,视频收藏或关注UP主,及时了解更多相关视频内容。
lv_timer_create() lv_timer_del() 其中,使用登录后复制lv_timer_create()函数创建一个定时器实例,并会向其中传送初始化参数,指定登录后复制本定时器的触发周期和登录后复制触发时执行的回调函数。而登录后复制lv_timer_del()函数会回收这个定时器的资源(包括变量,以及挂在定时器任务列表中的指针),以减轻LVGL后...

关于下面的程序,明明在裸机运行时没有问题,但是当其在RT-thread中运行时每当代码跑到lv_timer_handler()时就卡死,这是什么原因呢? 按道理来说,如果在裸机运行时已经考虑到了内存相关的问题,这里应该是不会运行出错的,但实际上,在RT-thread中跑lvgl时还要考虑到线程栈的大小。像这样在main函数中跑的程序,如果线程...
