| Abstract: | For the problem that the traditional grating scale signal proceeding method needs hardware lo4 circuit to quadruple frequency and differentiate direction, a method of velocity-position detection based on th C e timers＇ built-in quadruple frequency and differentiation direction functions of STM32F103VE is proposed, using 3 timers to realize the velocity detection, using 1 timer to realize the position detection. This scheme can make the velocity-position detection more reliable and more precise without increasing hardware costs, it has practical value. |
