WebSPI is the “Serial Peripheral Interface”, widely used with embedded systems because it is a simple and efficient interface: basically a multiplexed shift register. Its three signal wires hold a clock (SCK, often in the range of 1-20 MHz), a “Master Out, Slave In” (MOSI) data line, and a “Master In, Slave Out” (MISO) data line. WebTo acquire and release a bus, use the functions spi_device_acquire_bus () and spi_device_release_bus (). Driver Usage Initialize an SPI bus by calling the function spi_bus_initialize (). Make sure to set the correct I/O pins in the struct spi_bus_config_t. Set the signals that are not needed to -1.
