Changelog

Releases v1.10.1

  1. Using float instead of ulong for interval
  2. Prevent overflow of SAMD51 TCx by flagging error

Releases v1.10.0

  1. Avoid conflict with Servo library. Check Cannot use TimerInterrupt_Generic Library in the same time than Servo Library #11
  2. Prevent overflow of SAMD21 TCx by flagging error
  3. Modify all examples
  4. Update Packages_Patches

Releases v1.9.0

  1. Add TC4, TC5, TCC1 and TCC2 Timers to SAMD21
  2. Add example SAMD21_MultiTimers to demo the how to use all 6 SAMD21 timers simultaneously.
  3. Add functions attachInterruptInterval_MS() and setInterval_MS()
  4. Rewrite examples to take advantage of new functions and timers

Releases v1.8.0

  1. Fix bug introduced in v1.7.0 to SAMD21 TC3. Check Do I have a brick? I'm unable to upload sketches after using this library! #21

Releases v1.7.0

  1. Optimize code for setInterval() of SAMD21 TC3. Check setInterval on a running timer results in a period significantly longer than the specified period #17
  2. Update Packages_Patches

Releases v1.6.0

  1. Fix multiple-definitions linker error. Drop src_cpp and src_h directories
  2. Add example multiFileProject to demo for multiple-file project.
  3. Add support to many more boards, such as SAMD21E1xA, SAMD21G1xA andSAMD21J1xA
  4. Optimize library code by using reference-passing instead of value-passing
  5. Update all examples
  6. Update Packages_Patches

Releases v1.5.0

  1. Improve frequency precision by using float instead of ulong, Check PR change variable period from unsigned long to float #7
  2. Remove compiler warnings
  3. Update Packages' Patches
  4. Add strict option for PIO lib_compat_mode
  5. Split changelog.log from README.md

Releases v1.4.0

  1. Fix SAMD21 rare bug caused by not fully init Prescaler. Check Bug when going from a >20000us period to a <20000us period. The timer period become 4 times greater. #3

Releases v1.3.1

  1. Fix compile error to some SAMD21-based boards, such as ADAFRUIT_FEATHER_M0, ARDUINO_SAMD_FEATHER_M0, ADAFRUIT_METRO_M0_EXPRESS, ARDUINO_SAMD_HALLOWING_M0 and ADAFRUIT_BLM_BADGE. Check Doesn't compile with Adafruit Feather M0 #2.

Releases v1.3.0

  1. Add support to Sparkfun SAMD21 boards such as SparkFun_RedBoard_Turbo, SparkFun_Qwiic_Micro, etc.
  2. Add support to Sparkfun SAMD51 boards such as SparkFun_SAMD51_Thing_Plus, SparkFun_SAMD51_MicroMod, etc.
  3. Update examples to support Sparkfun boards.

Releases v1.2.0

  1. Add better debug feature.
  2. Optimize code and examples to reduce RAM usage
  3. Add Table of Contents

Releases v1.1.1

  1. Add example Change_Interval and ISR_16_Timers_Array_Complex
  2. Bump up version to sync with other TimerInterrupt Libraries. Modify Version String.

Releases v1.0.1

  1. Add complicated example ISR_16_Timers_Array utilizing and demonstrating the full usage of 16 independent ISR Timers.

Releases v1.0.0

  1. Permit up to 16 super-long-time, super-accurate ISR-based timers to avoid being blocked
  2. Using cpp code besides Impl.h code to use if Multiple-Definition linker error.
