MEM1_MAX_SIZE 10*1024: 如果你的开发板有外部ram,可以在lv_conf.h文件找到LV_MEM_ADR,这个宏定义默认为0,我们可以定义在外部ram的地址,例如正点原子的战舰开发板的外部ram为0X68000000,所以LV_MEM_ADR0X68000000 以上文章摘自:开源电子网 更多技术分享 ...
如果编译报错,可能是 SRAM 的空间不够用,我们可以把 lv_conf.h 文件中LV_MEM_SIZE宏改小。 如果触摸效果不灵敏,我们可以在 lv_conf.h 文件中有关扫描时间的宏LV_DEF_REFR_PERIOD改小。 五、FreeRTOS上移植LVGL 在裸机移植的时候,我们使用基本定时器为 LVGL 提供时基,而当有了系统之...

将Size 改成 64K,然后将 LV_MEM_ATTR 修改为 CCMRAM,内存起始地址 LV_MEM_ADR 修改为 0x10000000 在任务中添加一个测试指针,在使用 lvgl 分配一段动态内存: 然后仿真,看一下这个内存测试指针的地址,可以看到这段动态内存指向了 0x10000d44 的地址空间,该空间位于 CCMRAM 上...
