In a test circuit built with C3 = 1nF and R6 = 100kO (giving dt ˜ 100µs), the actual step size was measured as 59.7mV. Figure 3a Output waveform created by CW and CCW encoder rotation (4s/div., 2V/div ...

Figure 2a The circuit makes a gradual transition from single pulsing to multiple pulsing. Ultimately, when the encoder is rotated very quickly, the low-going edge at B retriggers IC3a before its Q ...

Rotary encoders are pretty interesting pieces of technology. They’re a solid way to accurately measure rotation including the direction. [David] recently wrote some software to handle these i… ...

Thus, the output of the “set/reset” circuit (DIR, U2, pin 6) indicates the direction that the rotary encoder is turned. As mentioned previously, each pulse is delayed by the low-pass filter R1 ...

[Rupert] got his V-USB/ATtiny85/rotary encoder circuit working, and at the expense of a ‘mute’ control, also added an awesome looking RGB LED ring powered by Adafruit’s Neopixels.

UNTERPREMSTAETTEN, Austria-- (BUSINESS WIRE)--The new AS5601 contactless rotary position sensor from ams AG (SIX: AMS), a leading provider of high performance analog ICs and sensors, gives ...
