QuickPID 2.3.2

Version 2.3.2

• Removed fixed point calculations as the speed benefit was very minimal.
• Prevent integral windup if output exceeds limits.
• Added the following new functions that return the P, I and D terms of the calculation.

    float GetPeTerm();           // proportional on error component of output 
    float GetPmTerm();           // proportional on measurement component of output
    float GetIterm();            // integral component of output
    float GetDterm();            // derivative component of output

QuickPID 2.3.1

• Resolved Kp windup as noted in issue #6. Algorithm reverts to upstream library, but with fixed point math option and newer controller direction method maintained.
• Updated AutoTune examples and documentation.
• Default AutoTune outputStep value in examples (and documentation) is now 5.

QuickPID 2.3.0

• New AutoTune class added as a dynamic object to reduce memory if not used, thanks to contributions by gnalbandian (Gonzalo).
• AutoTune now works for a reverse acting controller.
• AutoTune configuration parameters include outputStep, hysteresis, setpoint, output, direction and printOrPlotter.
• Defined tuningMethod as an enum.
• Updated AnalogWrite methods for ESP32/ESP32-S2.

QuickPID 2.2.8

AutoTune function is now non-blocking, no timeouts are required, exists in a sketch and uses Input and Output variables directly.

QuickPID 2.2.7

• Fixed REVERSE acting controller mode.
• now using src folder for source code
• replaced defines with enumerated types and inline functions

QuickPID 2.2.6

• Changed Input, Output and Setpoint parameters to float.
• Updated compatibility with the ESP32 AnalogWrite

QuickPID 2.2.2

• Added compatibility with the ESP32 Arduino framework.
• Added full featured AnalogWrite methods for ESP32 to control up to 9 PWM and 2 DAC signals.

QuickPID 2.2.1

• Even faster AutoTune function
• AutoTune now determines the controllability of the process
• Added AMIGO_PID tuning rule
• Added GetTd() function to display dead time

QuickPID 2.2.0

Includes enhanced AutoTune, 8 tuning rules to choose from and GetKu() and GetTu() display functions.
Updated documentation and AutoTune RC Filter example.

QuickPID 2.1.0 with AutoTune

• Added AutoTune function and documentation
• Added AutoTune_RC_Filter example and documentation
