DEVELOPMENT OF EMBEDDED SPI DRIVERS FOR A2O CORE PROCESSOR

The Serial-Peripheral Interface (SPI) protocol is one of the most widely used bus protocols for connecting processors to peripheral devices with low/medium data transmission speeds. SPI architecture is used to communicate between multiple peripherals and the processor in a SoC application. The slave is subject to the master’s power. The slave is represented by a sensor, monitor, or memory chip.Software connections between software programmes and hardware devices are called device drivers. Device drivers are thought to be particularly difficult to build as part of a complicated operating system. Low-level programming languages like C are commonly used to create them. Developers of device drivers must have a thorough grasp of the hardware and software systems they are working with. The C code will be translated to binary, which will then be sent into the processor to complete the operations using the chosen module. The goal of this project is to design and construct an SPI driver for the A2O core using the AMBA AXI4 bus interface. GCC will be used for driver development. To create drivers, the C programming language will be utilised
