State Machines and Timed State Machines in VHDL: FPGA Implementation of RS232, SPI and I2C Serial Communication Protocols Course

March 22 @ 11:00 am12:00 pm

Course Format: Live Webinar, 10 sessions, 1 hour per session

Times and Dates:  11AM (ET), March 22, 24, 29, 31, April 5, 7, 12, 14, 19, 21

  • Introduction: State machines are used to characterize the behavior of digital electronic circuits. State machines are widely used in industrial applications. For instance, they are used in factories for control applications. State machines are also used in communication technology. It is essential for an electronic engineer to have knowledge of state machines and their practical implementations. In this course, we first provide information about state machines, and then teach the implementation of state machines in VHDL language. We use VIVADO platform for development, simulation and FPGA programming purposes. For practical applications, we implement serial communication protocols such as RS232, SPI, I2C in VHDL. We consider the VHDL implementation of SPI protocol for AD7303 device, and also we implement I2C protocol for ADT7420 Digital Temperature Sensor.
