In general the bus consists of the - spid, spiq, spiclk and optionally spiwp and spihd signals. The SPI slaves are connected to these + miso, mosi, sclk and optionally quadwp and quadhd signals. The SPI slaves are connected to these signals in parallel. - - spiq - Also known as MISO, this is the input of the serial stream into the ESP32 + - miso - Also known as q, this is the input of the serial stream into the ESP32 - - spid - Also known as MOSI, this is the output of the serial stream from the ESP32 + - mosi - Also known as d, this is the output of the serial stream from the ESP32 - - spiclk - Clock signal. Each data bit is clocked out or in on the positive or negative edge of this signal + - sclk - Clock signal. Each data bit is clocked out or in on the positive or negative edge of this signal - - spiwp - Write Protect signal. Only used for 4-bit (qio/qout) transactions. + - quadwp - Write Protect signal. Only used for 4-bit (qio/qout) transactions. - - spihd - Hold signal. Only used for 4-bit (qio/qout) transactions. + - quadhd - Hold signal. Only used for 4-bit (qio/qout) transactions. * Device: A SPI slave. Each SPI slave has its own chip select (CS) line, which is made active when a transmission to/from the SPI slave occurs.
