Simple Peripheral Bus (SPB) Driver Design Guide
This section describes how to write a driver for a simple peripheral bus (SPB) controller device or for a peripheral device that is connected to an SPB. The SPB category includes buses such as I2C and SPI. The hardware vendor for an SPB controller device provides an SPB controller driver to manage the hardware functions in the controller. This driver might support a family of similar controller devices. The hardware vendor for an SPB-connected peripheral device provides an SPB peripheral driver to manage the hardware functions in the peripheral device. This driver might support a family of peripheral devices across a variety of hardware platforms that provide compatible SPBs.

Starting with Windows 8, driver support is available for simple peripheral buses (SPBs). The SPB category includes synchronous serial buses such as I2C and SPI. A serial bus transmits one bit of data at a time. A synchronous serial bus uses a clock signal to transmit consecutive data bits over the bus. | |

An SPB controller is a device that controls a simple peripheral bus (SPB) and that transfers data to and from the peripheral devices that are connected to the SPB. The hardware vendor for an SPB controller provides an SPB controller driver to manage the hardware functions in the controller. | |

An SPB peripheral device driver controls a peripheral device that is connected to a simple peripheral bus (SPB). The hardware registers of this device are available only through the SPB. To read from or write to the device, the driver must send I/O requests to the SPB controller. Only this controller can initiate data transfers to and from the device over the SPB. |
