初始化一个方法或另一个方法的代码略有不同,这些示例将检查USE_SD_CARD是被#定义来选择一个方法还是选择另一个方法。如果您知道您自己的项目只需要在一种或另一种类型上运行,那么您实际上只需要相应的初始化 使用SD卡时,声明以下两个全局变量: SdFat SD; // SD card filesystem Adafruit_ImageReader reader(S...
This project transforms an SD card reader into a functional USB stick, the program exposes the SD card as a USB mass storage device, allowing it to be accessed and used directly from a computer or other USB host. Features USB Mass Storage Device: Enables the SD card to function as a sta...
The ESP32 will be programmed to send commands to control the MP3 player module which song to pick from the SD Card, convert it into sound, and then send that sound to the speaker. We'll dive into the following aspects:How MP3 player works Connecting the speaker and MP3 player modules ...
I have been working on designing a PCB board for IoT usage and I am in a stage where all the peripherals and sensors work, except the micro-SD card reader. The board has the following sensors and modules connected in the respective pinout: 1. ATGM336H-5N31 - SD2, SD3 2. Ra-02 ...
