# 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](../sdmmc/README.md).
|
||
|
|
|
||
|
|
`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.
