确定原因或排除ESP32上内存溢出问题的故障,可以按照以下步骤进行: 1. 监测内存使用情况:使用ESP32的内存监测工具,如heap_caps_get_free_size()函数,可以获取当前可用...
使用xPortGetFreeHeapSize()、heap_caps_get_free_size()或相关函数来跟踪应用程序生命周期内的内存使用情况。尝试将泄漏缩小到单个函数或函数序列,在这些函数中,可用内存总是减少并且永远不会恢复。 一旦确定了正在泄漏的代码: ·在项目配置菜单中,导航到Component settings -> Heap Memory Debugging -> Heap tracing...
heap_caps_get_free_size(MALLOC_CAP_8BIT) 1. 4.1.3 释放空间 heap_caps_malloc()分配的空间可以用free来释放 4.2 启动时查看内存使用情况 4.2.1 DRAM 在启动时,可以通过idf.size 命令查看静态分配的内存。一般DRAM最大静态内存是160KB,剩余的只能作为堆区 同时,运行时DRAM大小可能...

Thanks for the clarification. I understand, just likeesp_get_free_heap_size()is equals toheap_caps_get_free_size((MALLOC_CAP_DEFAULT))? Another question, is the heap_caps_print_heap_info() function also intended for internal use or simply for providing more detailed information thanesp_get...

进入到 SPI RAM config ---> SPI RAM access method 选择 Make RAM allocatable using heap_caps_malloc 使用方法：char *buf =(char*)heap_caps_malloc(1024*1, MALLOC_CAP_SPIRAM);heap_caps_free(buf);查看剩余空间:heap_caps_get_free_size( MALLOC_CAP_SPIRAM );具体的...
I tried using xPortGetFreeHeapSizeCap to check the free heap of esp. I create a "reference.c" in the same folder with main.c, inside reference.c I define reference function: Code:Select all #include"reference.h"extern"C"{#include"esp_heap_alloc_caps.h"}externvoidSmbDaemon(){printf("...
