This example shows how use the utility libraries on which the' SD library is based in order to get info about your SD card. Very useful for testing a card when you're not sure whether its working or not. The circuit: * SD card attached to SPI bus as follows: ** MOSI - pin 11 o...
Using the SD library to create and remove files on a SD card 这个示例演示如何在SD卡上创建和销毁一个文件。请点击这里了解更多关于SD卡的信息。 硬件要求 Arduino or Genuino board Ethernet Shield (或者其他有SD插槽的开发板) 格式化后的 SD 卡 电路 图由Fritzing 绘制 Arduino或genuino板必须连接到 Et...

LED_BUILTIN 在Spresense Arduino Library中对应分配为LED0。 1.1.2. EEPROM Spresense 虽然没有内置EEPROM,但可以通过Flash内存模拟EEPROM。处理永久性数据时可以使用EEPROM程序库或是Spresense扩展板的SD卡。 1.1.3. Serial Spresense 上配备有2个串行端口(UART)、支持Serial 。主板上的USB端口可以通过将其定义...
SD Card Formatter 确保您选择的驱动器代表您的 SD 卡。你将要格式化它,所以如果你选择了错误的东西,它会清除你在那个驱动器上的所有东西。工具通常默认选择正确的,但是要仔细检查。明智的做法是断开任何其他外部存储设备。 确保“格式大小调整”设置为“开”。这将删除卡上的任何其他分区,并使用整个分区。将所有其他...

There is no CardInfo.ino in theSD library examples. You are running something from another architecture. Hi@lbernstone, thank you for your reply. I took the example from the arduino IDE. However if I run it on another computer, not my personal laptop, it works fine also on ESP32 board...

还有一个板载微型SD卡槽,可以让你存储可查找到的数据。这需要使用外部SD库,它其实不附带软件。本教程不涵盖SD卡。在无线SD卡的 Step 8(http://www.instructables.com/id/Arduino-Wireless-SD-Shield-Tutorial/step8/Prepare-the-SD-card/)中可以找到。
Arduino IDE 应该预装了 SD 库。在文件→ SD 示例下检查。如果不安装库。 将扩展板连接到您的 Arduino 并插入 SD 卡。上传程序 SDCardReadFiles 并运行它。如果一切正常,串行监视器应该列出 SD 卡上的所有文件 /* SDlistFilesThis example shows how print out the files in a directory on a SD cardThe ...
