五、ESP8266闪存中进行删除操作——SPIFFS.remove(file_name); 1.主要代码: 2.完整代码: 3.现象 六、ESP8266显示闪存文件系统信息 运行结果: 编辑 每一个ESP8266都有自己的闪存系统(全程 Serial Peripheral Interface Flash File System(SPIFFS)),即我们所说的flash存储,这里用于存放我们的用户代码等信息。下面我们...
(file_name, "r"); 以上SPIFFS函数有两个参数: 第一个参数是被操作的文件名称,本示例中该文件为/notes.txt 第二个参数"r" 代表读取文件信息。(如需了解如何写入信息,请参阅示例程序esp8266-flash-write) ***/ #include <FS.h> String file_name = "/taichi-maker/notes.txt"; //被读取的文件和名称...

esp8266-flash-write 程序目的/Purpose : 此程序用于演示如何向NodeMCU的SPIFFS中建立名为 notes.txt的文件,程序还将向该文件写入信息。 --- 函数说明: SPIFFS.open(file_name, "w"); 以上函数有两个参数一个参数是被操作的文件,本示例中该文件为/notes.txt 第二个"w" 代表写入文件信息。(如需了解如何...
write(file.read()); } file.close(); } else { Serial.println("Failed to open config file from SPIFFS"); } } void loop() { // 你的主程序逻辑 } 在这个综合应用示例中,程序首先连接到WiFi网络,然后挂载SPIFFS文件系统。接着,它检查一个名为 config.txt 的文件是否存在以及是否包含数据。如果...
