IS bounce 2 compatible with teensy 3.1?

I would like to use bounce 2 in my project because there are 2 versions (of my project)

the setup checks for a pin being low and then changes the mapping of the switches to pins accordingly. unfortunately bounce 1 wants you to assign pins before setup.

if someone has tried it and it works, that would save me some potential grief!

thanks

yes that is the one.

my sourcecode is very huge to post here, but i initialize a button with a variable called "FXButton" which was set to the pin (3) that is used in the first hardware version.

Code: 
Bounce FXCycleButton = Bounce(FXButton, 20);

then in setup, i check a pin to see if there is anything connected (an LED that is on one version but not the other)

Code: 
void setup() {

  pinMode(aout2, OUTPUT);//ignore
  pinMode(oSQout, OUTPUT);//ignore
  pinMode(31, INPUT_PULLUP);//turn this to an input to check for presence of LED. (hw2 detect)

  if (digitalRead(31) == 0) { //detect if an LED is on the pin. if so, then it is 2.0 hardware module.
    IsHW2 = 1;

now i have detected "is hardware 2" and need to change the pin that the FXCycleButton bounce object is attached to.

I would prefer not to use the bounce2 library if possible because it means users will have another thing to download, and there are quite a lot of these out in the wild (neutron sound orgone accumulator)

i hope that makes sense.
 
mmh, if it's just the one switch, couldn't you just use some custom code? you can still use bounce for the others.

unless i'm missing something:

Code: 
if (IsHW2)  FXButton = thispin;
else FXButton = thatpin;


and something like :

Code: 
 if (!digitalReadFast(FXButton) && (millis() - _TIMESTAMP > _DEBOUNCE)) {
   
     _TIMESTAMP = millis();
    // do something

}
 
I haven't tested that "Bounce2" copy, but I just looked at its code. It certainly looks like it should work.

Is there any problem you're seeing?
 
Bounce2 works, but downloading and installing the library is a problem for some people.
i did not realize it was just counting millis though(i thought it was using interrupts), i will just add my own function for it.

thanks for the help!
 
I found an easy fix. with Bounce1 you CAN reassign the pin number after creating the bounce.

create the bounce as normal before setup

Code: 
Bounce FXCycleButton = Bounce(FXButton, 20);

then after testing the pin in setup (which changes the value of FXButton pin)

Code: 
FXCycleButton = Bounce(FXButton, 20);
