Automatic Multiple Channel Serial I/O Interfacing Using FPGA Kit

The Digital input and output interface could be a important part for a machine needed to be interacted with its setting. Even though a main processing unit (MPU) utilized within the machine has its own Digital input output channel, for some cases, the machine should use plenty of input output channel than those the MPU can offer. To avoid this downside, a process board interfaced on to the MPU via serial communication is intended. If the MPU connect with multiple process boards directly, it's going to waste sometime to process of communication data. The inessential measure of the MPU and likelihood to have many boards connected, a serial interface unit supported FPGA is developed to help the MPU to talk with process boards. The FPGA unit automatically browses serial signals from each process boards and save understood data to share registers for MPU to scan. The FPGA unit put together impromptu reads registers written by MPU and send registers values to process boards automatically.
