Import time from rotary_irq_esp import RotaryIRQ r = RotaryIRQ( pin_num_clk = 12, Note: None of the arguments are checked for configuration errors. Remove_listener(function) remove a previously added callback functionД¬lose() deactivate microcontroller pins used to read encoder Retained for backwards compatibility)ДЄdd_listener(function) add a callback function that will be called on each change of encoder count Redundant with the addition of the set() method.

set(value=6) change encoder value to 6.

set(min_val=0, max_val=59) change encoder bounds - useful to set minutes on a clock display.

None indicates no change to the configuration parameter

See constructor for argument descriptions. Set encoder value and internal configuration parameters. Set(value=None, min_val=None, max_val=None, reverse=None, range_mode=None) RotaryIRQ.RANGE_UNBOUNDED(default) RotaryIRQ.RANGE_WRAP RotaryIRQ.RANGE_BOUNDEDД®nable internal pull up resistors (use when rotary encoder hardware lacks pull up resistors)Д®ncoder has no bounds on the counting rangeД®ncoder will count up to max_val then wrap to minimum value (similar behaviour for count down)Д®ncoder will count up to max_val then stop. Maximum value in the encoder range (not used when range_mode = RANGE_UNBOUNDED) Note: -d1 option is often needed for ESP8266 boards

The use of the state table leads to accurate encoder counts and effective switch debouncing. Transition state machineДЄ gray code based transition state table is used to process the DT and CLK changes. The ISR interrupts normal code execution to process state changes in the encoder pins. This interrupt causes a python-based interrupt service routine (ISR) to run. Whenever encoder pins DT and CLK change value a hardware interrupt is generated. Key Implementation Features Interrupt based It uses two GPIO pins configured to trigger interrupts, following Ben Buxton's implementation: This is a robust implementation providing effective debouncing of encoder contacts. Works with Pyboard, Raspberry Pi Pico, ESP8266, and ESP32 development boards.
