SDMMC Host Driver

SD Host side related components are:

  • sdmmc
  • esp_driver_sdmmc (current component)
  • esp_driver_sdspi

For relationship and dependency among these components, see SD Host Side Related Component Architecture.

esp_driver_sdmmc components holds SDMMC Host driver for ESP SDMMC peripheral, this driver provides APIs to help you:

  • do SD transactions (under SD mode) via ESP SDMMC peripheral.
  • tune ESP SDMMC hardware configurations, such as clock frequency, bus width, etc.
  • ...

You can

  • use this driver to implement sdmmc protocol interfaces
  • directly use esp_driver_sdmmc APIs

to communicate with SD slave devices under SD mode.
