Esp32 change spi pins

One solution can be redefining the pins used as SPI, instead of the pins used by default. Here are some links that can help:If you use all of the pins for SPI2 or all of the pins for SPI3, using those pins is slightly faster, since the signals do not have to be routed through the GPIO matrix. This has the advantage of having a lower input delay (which is important at high speeds to avoid issues with MISO setup time) and that you can operate the SPI bus at 80 MHz (as opposed to 40 MHz with the GPIO matrix).DIO - SPI host uses the "Dual I/O Fast Read" command (BBh). Two SPI pins are used to write the flash address part of the command, and to read flash data out. Therefore these phases need half the clock cycles compared to standard SPI. DOUT - SPI host uses the "Dual Output Fast Read" command (3Bh). Two SPI pins are used to read flash data out. farmhouse christmas tree decorations ideas
The ESP32 integrates 4 SPI peripherals: SPI0, SPI1, SPI2 (commonly referred to as HSPI ), and SPI3 (commonly referred to as VSPI ). SP0 and SP1 are used internally to communicate with the built-in flash memory, and you should not use them for other tasks. You can use HSPI and VSPI to communicate with other devices.Files changed can be seen here: include overloads to specify pins and SPI bus · michaelschnyder/[email protected] (github.com).
