# TeensyTimerTool
The TeensyTimerTool is a library that provides a generic, easy to use interface to the hardware timers of the PJRC Teensy boards. In addition, it provides up to 20 highly efficient software timers that use the same interface. All timers can be used in periodic and one-shot mode. Currently the library supports the ARM T3.X and T4.0 boards.
- This way to the corresponding PJRC **[forum post](https://forum.pjrc.com/threads/59112-TeensyTimerTool)**
- This way to the documentation in the **[TeensyTimerTool WIKI](https://github.com/luni64/TeensyTimerTool/wiki)**

sentence=Generic Interface to Teensy Timers
paragraph= TeensyTimerTool is a library that provides a generic, easy to use interface to the hardware timers (FTM, GPT, QUAD, PIT) of the PJRC Teensy boards. In addition, it provides up to 20 highly efficient software timers based on the cycle counter or the RTC (32 and 64bit) that use the same interface. All timers can be used in periodic and one-shot mode. Currently the library supports the ARM T3.X and T4.0 boards. You can either pick a free timer from a pool or specify exactly which of the available hardware or software timer modules you want to use.
