WebMar 11, 2024 · "The ESP32 has four SPI peripheral devices, called SPI0, SPI1, HSPI and VSPI. SPI0 is entirely dedicated to the flash cache the ESP32 uses to map the SPI flash device it is connected to into memory. SPI1 is connected to the same hardware lines as SPI0 and is used to write to the flash chip. HSPI and VSPI are free to use." and... WebDec 13, 2012 · Also, what's not commonly explained in SPI Flash datasheets, because it's an inherent part of the SPI protocol, which is also critical, is that for every byte one transmits on the SPI bus, one receives a byte in return. Also, one cannot receive any bytes, unless one transmits a byte.
