SDSPI Host Driver

SD Host side related components are:

  • sdmmc
  • esp_driver_sdmmc
  • esp_driver_sdspi (current component)

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

esp_driver_sdspi components is a driver based on ESP GPSPI master driver to help you:

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

You can

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

to communicate with SD slave devices under SDSPI mode.
