Product Introduction
The EC11 rotary encoder is widely used in car DVD players, car navigation systems, and car audio systems, and is often referred to as a car encoder. Rotary Encoders are mainly used for parameter control in frequency adjustment, height adjustment, temperature adjustment, and volume adjustment. Please note that encoders should be stored away from high temperature, humid, and corrosive environments. For unused products remaining after unpacking, please store them in a moisture-proof and poison-proof environment.

EC11 Note
- The encoder pulses count method should be designed with taking operating speed,sampling time and esign of the microcomputer software into cosideration.
- Care must be taken not to expose this rotary encoder to water or dew to prevent possible problemin pluses output waveform.
- During actual use of EC11, there are often issues of jitter. Sometimes, we just rotate by one grid, but the microcontroller enters two interrupt processes. If we need a smoother operation, that is, rotating by one grid only triggers one external interrupt, at this point, we need to perform anti-jitter processing on the EC11 encoder.
① Hardware anti-jittering
This is usually achieved by using parallel capacitors. By taking advantage of the property that capacitor voltage does not change abruptly, it is filtered.
② Software anti-jittering
This is generally done through the use of delay. By avoiding the period when mechanical jitter occurs, the purpose of filtering is achieved. For example, our independent buttons often use the method of software filtering.
- Anti-jittering thinking
- Set up a timer interrupt with a timing period of 1ms.
- EC11 enters an external interrupt, temporarily disabling it for 50ms (or even shorter, such as 20ms), and activates the delay variable to start timing.
- After the timing is completed, clear the interrupt flag and the delay variable, and enable the external interrupt again.
EC11 Application
The EC11 rotary encoder is widely used in electronic devices that require precise adjustment and position detection, including volume control in audio equipment (such as mixing consoles, amplifiers), home appliance interfaces (oven, washing machine knobs), industrial equipment (CNC machines, 3D printers), vehicle systems (central control knobs, dashboard adjustment), and smart home applications (light brightness, curtain control), etc. Its long service life and stable performance make it an ideal choice for human-machine interaction control, especially suitable for various electronic devices that require reliable knob operation.
