Introduction to the Serial Peripheral Interface - Arduino

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. Web2. feb 2012 · How do I write an “SPI Master Controller Driver”?¶ An SPI controller will probably be registered on the platform_bus; write a driver to bind to the device, whichever bus is involved.
