Update

Update

- autoTune parameters `outputStep`, `hysteresis`, `Setpoint` and `Output` are now float
- minimum `outputStep` is now 0 (previously 5).

Update

- Now using 2-stage integral anti-windup strategy
- Better organized compute code
- Some cleanup and documentation updates

Update

Assorted minor updates

Update

Version update

Update

    Faster PID read-compute-write cycle (Arduino UNO): QuickPID = 51µs, PID_v1 = 128µs
    Updated compute() function
    New Variable Derivative on Error to Derivative on Measurement parameter DOn
    Updated PID Query Functions: GetPterm(); GetIterm(); GetDterm();
    Updated all examples and documentation

New TIMER mode

#### QuickPID 2.3.3

- Added new `TIMER` mode which is used when the PID compute is called by an external timer function or ISR. In this mode, the timer function and SetSampleTimeUs use the same time period value. The PID compute and timer will always remain in sync because the sample time variable and calculations remain constant. See AutoTune_`TIMER` mode example [AutoTune_Filter_TIMER_Mode.ino](https://github.com/Dlloydev/QuickPID/blob/master/examples/AutoTune_Filter_TIMER_Mode/AutoTune_Filter_TIMER_Mode.ino)
