使用SD库中函数里参数可以包含以正斜杠/分隔的路径,例如" directory / filename.txt"。由于工作目录始终是SD卡的根目录,因此无论文件名是否包含斜杠,其名称都指向同一文件(例如," / file.txt"等同于" file.txt")。从1.0版开始,SD库支持打开多个文件。 开发板与SD卡之间的通信使用SPI,注意: 必须连接
uint64_t cardSize = SD.cardSize() / (1024 * 1024); Serial.printf("SD Card Size: %lluMB\n", cardSize); listDir(SD, "/", 0); createDir(SD, "/mydir"); listDir(SD, "/", 0); removeDir(SD, "/mydir"); listDir(SD, "/", 2); writeFile(SD, "/hello.txt", "Hello "); ...
