LV_MEM_SIZE 报错 由于安装的kvm需要扩容,研究了下lvm的使用。 LVM(Logical Volume Manager)逻辑卷管理器,做法是将物理分区通过软件组合未一个独立的大磁盘(VG,卷组),然后把这个大磁盘分成新的分区(LV,逻辑卷)挂载使用。 物理分区加上8e的sysem id之后,通过pvcreate转成物理卷(pv),调整System ID用fdisk命令。

DPI: #define LV_DPI 100 提供给lvgl的空间: #define LV_MEM_SIZE (32U * 1024U) 其中调整LV_DPI 可以调整各控件间的紧凑,可根据实际情况进行更改;LV_MEM_SIZE 为lvgl可用空间,资源允许的情况下可以稍微设大些,这个设置过小的话,在跑一些稍微复杂的demo时界面就会刷不出来。 这里只是列出了几个常用的配置...
