GorgonMeducer perf_counter A dedicated performance counter for Cortex-M systick. It shares the SysTick with users' original SysTick function without interfere it. This library will bring new functionalities, such as performance counter, delay_us and clock() service defined in time.h https://raw.githubusercontent.com/GorgonMeducer/perf_counter/CMSIS-Pack/cmsis-pack/ https://github.com/GorgonMeducer/perf_counter/issues lib/LICENSE https://github.com/GorgonMeducer/perf_counter.git - Include stddef.h in perf_counter.h to solve missing NULL definition issue. - Improve support for IAR - Fix issues found in foreach - Other minor update - Add CMSIS Dependency Check - Add options for selecting between source code and library. - Add GCC support to CMSIS-Pack Cortex-M SysTick Performance Analaysis Arm Compiler 5 (armcc) or Arm Compiler 6 (armclang).
