如何在 ESP32 上初始化 NVS

首先，使用以下命令包含 ESP32 NVS 库：

init_nvs.cpp

#include <nvs.h>

#include <nvs.h>

全局声明

nvs_handle_declaration.cpp

nvs_handle_t myNVS = 0;

nvs_handle_t myNVS = 0;

然后你可以

init_nvs_function.cpp

void InitNVS() {
    esp_err_t err;
    if((err = nvs_open("MyLabel", NVS_READWRITE, &myNVS)) != ESP_OK) {
        Serial.printf("Failed to open NVS: %s\r\n", esp_err_to_name(err));
        return;
    }
}

void InitNVS() {
    esp_err_t err;
    if((err = nvs_open("MyLabel", NVS_READWRITE, &myNVS)) != ESP_OK) {
        Serial.printf("Failed to open NVS: %s\r\n", esp_err_to_name(err));
        return;
    }
}

你可以任意选择 MyLabel，只要字符串不太长。我的建议是为你的应用程序选择一个唯一标识符。
