How to enable REVERSE?

[sabellnikov]

Hello, @Dlloydev, I'm newby in programming. Don't judge me.

I wanna enable REVERSE, but if I put
void SetControllerDirection(Reverse); // Set controller action to direct (default) or reverse

It doesn't building at all... Please give me an example how to use "internal state" function in any basic examples of your code.
Thank you!

Here's an example ...

//   PID Controller Direction Test

#include "QuickPID.h"

//Define Variables we'll be connecting to
float Setpoint, Input, Output;

float Kp = 2, Ki = 5, Kd = 1;

//Specify PID links
QuickPID myPID(&Input, &Output, &Setpoint);

void setup()
{
  Serial.begin(115200);

  //print the default controller direction (0) is direct, (1) is reverse
  Serial.print("Default Direction: ");
  Serial.println(myPID.GetDirection());

  //now set the controller direction to reverse
  myPID.SetControllerDirection(myPID.Action::reverse);

  // or you can use
  myPID.SetControllerDirection(1);

  // check and print the direction
  Serial.print("New Direction: ");
  Serial.println(myPID.GetDirection());

  //now set the controller direction to direct
  myPID.SetControllerDirection(myPID.Action::direct);

  // or you can use
  myPID.SetControllerDirection(0);

  // check and print the direction
  Serial.print("New Direction: ");
  Serial.println(myPID.GetDirection());
}

void loop() {
}

Thank you!)

but if I'd like to change sample time? I should use:
myPID.SetSampleTimeUs(myPID.uint32_t NewSampleTimeUs::10000);
But it doesn't compile again :((

Thank you for best library, I've spent many time reading your article, but I should ask you to write more siimple examples how to use "settings" for library....

Thank you, I will consider this for the next release, but my workload is too high at the moment.
To use this function is simply:

// Set the sample time to 10000 µs.
myPID.SetSampleTimeUs(10000);
