# SPI BUS selection
|
||||
|
||||
|
||||
The ESP32 series has three SPI BUSs.
|
||||
SPI1_HOST is used for communication with Flash memory.
|
||||
You can use SPI2_HOST and SPI3_HOST freely.
|
||||
When you use SDSPI(SD Card via SPI), SDSPI uses SPI2_HOST BUS.
|
||||
When using this module at the same time as SDSPI or other SPI device using SPI2_HOST, it needs to be changed to SPI3_HOST.
|
||||
When you don't use SDSPI, both SPI2_HOST and SPI3_HOST will work.
|
||||
Previously it was called HSPI_HOST / VSPI_HOST, but now it is called SPI2_HOST / SPI3_HOST.
