Abstract:
The use of Field Programmable Gate Arrays (FPGAs) requires low level programming. This makes it difficult to have a friendly user interface. The presented work explains FPGA techniques in detail. There are few works demonstrating an application integrating FPGA and ergonomic user-interface techniques. This article describes the connection of an FPGA to a Raspberry PI using a Serial Peripheral Interface (SPI) link. A Python SPI driver is developed on the Raspberry side. A Very High-Speed Integrated Circuit Hardware Description Language (VHDL) driver is developed on the FPGA side. A Web client-server application is developed to demonstrate the usage of SPI link and its integration with a standard Web application to control the FPGA inputs and outputs.
