What is an SPI Controller Windows Driver?

An SPI (Serial Peripheral Interface) Controller is a hardware interface used for communication between a microcontroller or processor and various peripheral devices like sensors, memory chips, and other embedded systems components. The SPI protocol is commonly used in embedded systems for high-speed data transfer.

In a Windows environment, an SPI Controller Windows driver allows your computer to communicate with external SPI-based devices, typically through a connected SPI controller on a microcontroller, FPGA, or an embedded system. The driver ensures that your Windows operating system can interact with the hardware using the SPI protocol, enabling applications to send and receive data to/from SPI peripherals.
