一、定义全局容器变量static lv_obj_t *contanier1= NULL; static lv_obj_t *contanier2= NULL;二、在LVGL初始化代码后初始化容器contanier1= lv_obj_create(lv_scr_act()); lv_obj_set_size(contanier1,320,240);…
lvscr.scr应用程序错误方式如下。1、可能系统初选了问题，查看一下有没有需要进行更新，检查有没有高位的漏洞。2、重装系统了，但是要注意提前备份数据。

This paper addresses three aspects of LVSCR protection devices namely, LVSCR layout optimization, triggering techniques, and the impact of stress signal slew-rate on ESD performance. Circuit techniques to achieve bi-modal triggering for LVSCR ESD protection schemes are presented. The low voltage trig...
