Scalar variables using the Commander

Commander interface has a built-in feature for setting/getting a scalar variable. To use it with a desired variable (ex. variable) use the callback commander.scalar(&variable,cmd).

For example if you have a variable added to the commander:

Commander commander = ...

// define my variable
float my_variable = 1.234;

void onScalar(char* cmd){ commander.scalar(&my_variable,cmd); }
void setup(){
  ...
  commander.add('A',onScalar,"my variable");
  ...
}
void loop(){
  ...
  commander.run();
}

You will be able to configure (set and get) it from serial monitor:

$ ?           # list available commands 
A: my variable
$ A           # get time constant
1.234
$ A0.05       # set time constant
0.05
$ A           # get time constant
0.05
