Circuit design and implementation of dental system controller based on FPGA

Abstract EN

In this paper, a hardware circuit was designed and implemented for controlling the time of dental curing system by using VHDL as a design tool and the FPGA as target technology to create a counter.

The control was achieved by designing a card containing seven segment, halogen lamp and buzzer and connect these component with FPGA .The time which needed for curing to towel was controlled automatically by preset value which was input from a push-button switch.

Buzzer signal used to state that the needed time of counter is over and the device was stopped from the operation.

The design is implemented in a Spartan-3E Starter Kit.

The speed of counter can be controlled by using the clock divider of the kit (50 MHz) to the quite clock to get the necessary delay between the numbers of counter.

The advantage of using FPGA is its performance which is supported with hardware parallelism , flexibility, reliability and long time maintenance.
