Set(value=None, min_val=None, max_val=None, reverse=None, range_mode=None) RotaryIRQ.RANGE_UNBOUNDED(default) RotaryIRQ.RANGE_WRAP RotaryIRQ.RANGE_BOUNDEDĮnable internal pull up resistors (use when rotary encoder hardware lacks pull up resistors)Įncoder has no bounds on the counting rangeĮncoder will count up to max_val then wrap to minimum value (similar behaviour for count down)Įncoder 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

rotary_irq_rp2.py Platform-specific code for Raspberry Pi Pico development boardsĬopy files to the internal MicroPython filesystem using a utility such as ampy or rshellĪmpy example below for Pyboards. rotary_irq_pyb.py Platform-specific code for Pyboard development boards. rotary_irq_esp.py Platform-specific code for ESP8266 and ESP32 development boards. platform-independent file rotary.py - a core file for all development boards. The use of the state table leads to accurate encoder counts and effective switch debouncing. Transition state machineĪ 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. Jivelite raspberry pi rotary encoder pro driver#
