SD Card Example

[中文]

This document explains the SD card example provided by the official ESP-IDF, aiming to help developers quickly understand the implementation, configuration methods, and usage logic of the SD card in ESP-IDF, and provide practical application references.

For ease of understanding and use, the content of the document is divided into two parts:

  1. General Steps Document: Introduces the SD card and explains its common operation process, providing a unified reference for the example.

  2. Example Document: Explains the implementation of each example by function, avoids repetition by referencing the general steps document for common parts, and only retains the logic and parameter settings unique to the example.

This layered structure facilitates understanding the protocol itself and its overall configuration process through the general steps document, and then learning the implementation details of specific functions through the example document, thereby more efficiently understanding the working principle and design method of the SD card module. You can first view the basic explanation and common operation steps of the SD card through General Steps. The official ESP32 also provides related reference materials: SD/SDIO/MMC Driver, SDMMC Host Driver and SD SPI Host Driver.
