The Circuit Design of Visual Fatigue Detection and Elimination Based on STM32
A visual fatigue detection and elimination circuit based on SMT32 is designed by using the visual retention characteristics of human eyes.Select STM32F103RCT6 as the control core,programming control circuit work.The hardware circuit includes power supply circuit,STM32 minimum system circuit,key circuit,display circuit and sound circuit.The software design includes main program,delay subroutine,fatigue detection subroutine,flash frequency adjustment subroutine and fatigue elimination subroutine.Through the joint debugging operation of software and hardware,the circuit design goal of detecting and eliminating human eye fatigue is realized.
