SPI Slave driver is a program that controls {IDF_TARGET_NAME}'s SPI peripherals while they function as slaves.
SPI Slave driver is a program that controls {IDF_TARGET_NAME}'s General Purpose SPI (GP-SPI) peripheral(s) when it functions as a slave.
Overview of {IDF_TARGET_NAME}'s SPI peripherals
-----------------------------------------------
{IDF_TARGET_MAX_SLAVE_PERIPH_NUM:default="2", esp32c3="1", esp32c2="1", esp32c6="1", esp32h2="1"}
On {IDF_TARGET_NAME}, {IDF_TARGET_MAX_SLAVE_PERIPH_NUM} SPI controllers are available for general purpose usage. A certain SPI controller has an independent signal bus with the same name.
.. only:: esp32
.. note::
On ESP32, HSPI refers to SPI2, VSPI refers to SPI3.
For more hardware information about the GP-SPI peripheral(s), see *{IDF_TARGET_NAME} Technical Reference Manual* > *SPI Controller* [`PDF <{IDF_TARGET_TRM_EN_URL}#spi>`__].
