Implementation of a Web-based Interface for Remote Access to a FPGA Board

Remote laboratories allow access to different types of equipment and devices from distant places, in the current context their use has increased in engineering education synchronously or asynchronously. That is why this article describes the development and implementation of a web-based interface that allows simulating control of the physical switches and pushbuttons of an FPGA board and visualize through the web the results of the execution of experiments on the FPGA board. We detail the connection and configuration between the FPGA-DE2-115 board and a Raspberry PI 4 (RPI), which can be extended to other types of FPGA boards. In addition, a web-based interface with Flask-Python was developed that allows the platform to be intuitive and interactive, this provides a great educational contribution when implementing a microelectronics laboratory or digital systems with remote access control. Finally, the web interface code is available on Github so that it can be improved and used for academic purposes.
