XOR not working correctly #9

Open Ansbjerg opened 7 months ago

Ansbjerg commented 7 months ago

Been trying to use XOR with 3 inputs = XOR(3) But it does not behave as it should (see attached video)

If you have 3 switches that outputs TRUE, XOR(3) should return TRUE but is stays FALSE. Also tried with XOR(4) and up with same result. Only XOR(2) works as it should...

Looks to be working as intended. See https://electronics.stackexchange.com/a/93719, It is implemented as "one and only one".

Feel free to make a PR to add a new variant, or a configuration to change behavior. Alternatively, you can instead cascade multiple XOR gates to get the desired functionality I think.

Hi,

Weird as all other programs use this version of XOR (see below). And yes - I had to cascade XOR(2) to get the right XOR(3) function. Where and how can I make a request for this function to be added?

You don't. You fork this repository, implement it and then make a Pull Request to have it added.

Alternatively, you can create a composite (reusable component) instead, with as many inputs as you need.
