Struct SdCardDriver 

Source 
pub struct SdCardDriver<T> { /* private fields */ }
Expand description

A high-level SD-Card driver.

This driver is used to interface with an SD-Card by wrapping one of the two SD Host drivers:

  • SD-SPI Host driver (SdSpiHostDriver)
  • SD-MMC Host driver (SdMmcHostDriver) - on MCUs that do have an SD-MMC peripheral (ESP32, ESP32S3 and ESP32P4)

The interface allows reading, writing and erasing sectors, as well as reading and writing arbitrary-length bytes.

Currently, all interaction with the SD-Card driver is via the native, unsafe sys::sdmmc_* functions.
