4.2
Application background Key Technology EC11 digital rotary encoder on the STM32F103 platform, the use of interrupt query method to determine whether the clockwise or counter clockwise rotation. At the same time, there is the function of the middle button. Hardware schematics and physical map as above. Because of the stability of the encoder pin on the increase in the filter. Current code can be normal use.
