F429 移植了lvgl 和使用外部ram

无情一刀

F429 移植了lvgl  和使用外部ram

我看lv_conf.h有一个LV_MEM_CUSTOM 这个变量 我是设置为1
然后下面分配的内存函数都有已经写了    但是运行起来  会有一些意想不到的问题，LV_MEM_CUSTOM关了这个问题就没有了
希望各位看看 是不是还需要修改什么地方




#define LV_MEM_CUSTOM 1
#if LV_MEM_CUSTOM == 0
    /*Size of the memory available for `lv_mem_alloc()` in bytes (>= 2kB)*/
    #define LV_MEM_SIZE (38U * 1024U)          /*[bytes]64*/

    /*Set an address for the memory pool instead of allocating it as a normal array. Can be in external SRAM too.*/
    #define LV_MEM_ADR 0     /*0: unused*/
    /*Instead of an address give a memory allocator that will be called to get a memory pool for LVGL. E.g. my_malloc*/
    #if LV_MEM_ADR == 0
        //#define LV_MEM_POOL_INCLUDE your_alloc_library  /* Uncomment if using an external allocator*/
        //#define LV_MEM_POOL_ALLOC   your_alloc          /* Uncomment if using an external allocator*/
    #endif

#else       /*LV_MEM_CUSTOM*/
    #define LV_MEM_CUSTOM_INCLUDE <stdlib.h>   /*Header for the dynamic memory function*/
    #define LV_MEM_CUSTOM_ALLOC   user_malloc
    #define LV_MEM_CUSTOM_FREE    user_free
    #define LV_MEM_CUSTOM_REALLOC user_realloc
#endif     /*LV_MEM_CUSTOM*/
