Changelog

Releases v1.3.0

  1. Fix poor-timer-accuracy bug. Check Poor accuracy on timer interrupt frequency or interval. #4

Releases v1.2.1

  1. Fix New Period display bug. Check random dropouts #4
  2. Display informational warning only when _PWM_LOGLEVEL_ > 3
  3. Update examples

Releases v1.2.0

  1. Fix multiple-definitions linker error. Drop src_cpp and src_h directories
  2. Improve accuracy by using float, instead of uint32_t for dutycycle. Check Change Duty Cycle #1
  3. DutyCycle to be optionally updated at the end current PWM period instead of immediately. Check DutyCycle to be updated at the end current PWM period #2
  4. Optimize library code by using reference-passing instead of value-passing
  5. Add example multiFileProject to demo for multiple-file project
  6. Update examples accordingly

Releases v1.1.0

  1. Add functions to modify PWM settings on-the-fly
  2. Add example to demo how to modify PWM settings on-the-fly

Releases v1.0.1

  1. Fix platform in library.json

Initial Releases v1.0.0

  1. Initial coding to support RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, etc. using RP2040 ArduinoCore-mbed mbed_nano or mbed_rp2040 core
  2. The hybrid ISR-based PWM channels can generate from very low (much less than 1Hz) to highest PWM frequencies up to 1000Hz with acceptable accuracy.
