要查看ESP32的RAM占用情况,你可以通过以下几种方法来实现: 1. 使用ESP-IDF开发框架 如果你使用的是ESP-IDF开发框架,可以通过以下API来查看RAM占用情况: 查询系统剩余堆大小: c size_t dram = heap_caps_get_free_size(MALLOC_CAP_8BIT); printf("Remaining DRAM size: %d byte
if (heap_caps_match(&temp_heaps[i], MALLOC_CAP_8BIT|MALLOC_CAP_INTERNAL)) { /* use the first DRAM heap which can fit the data */ heaps_array = multi_heap_malloc(temp_heaps[i].heap, sizeof(heap_t) * num_heaps); if (heaps_array != NULL) { break; } } } assert(heaps_array...
最后，使用heap_caps_malloc函数为显示屏分配一个颜色缓冲区，其大小为lv_color_t类型乘以屏幕宽度乘以屏幕高度。这样，我们就为LVGL准备好了一个用于绘制的缓冲区。8, MALLOC_CAP_INTERNAL | MALLOC_CAP_8BIT);if (!disp_draw_buf1 && !disp_draw_buf2) {Serial.println("LVGL disp_draw_buf allocate faile...

if((buffer=(char *)malloc(15000*sizeof(char)))==NULL) printf("NO MEMORY"); questions: 1) is 10KB max size buffer tx client http? 2)if I got 180KB+ of free memory..why can't use 15KB or more with malloc? 3) using MALLOC_CAP_8BIT the correct way to know how much free me...

if (xTaskCreate(my_task, "my_task", 4096, NULL, 1, NULL) != pdPASS) { printf("Task creation failed!\n"); } } 调试技巧 使用ESP_LOGE打印错误日志。 通过idf.py monitor查看具体崩溃原因(如abort()信息)。 使用heap_caps_print_heap_info(MALLOC_CAP_8BIT)检查内存碎片。
