Cool:) Maybe also change the names of in/ouputs to match that in the drawing in the beginning of the thread: instead of a,b,c,d maybe S0,S1,S2,S3 etc:) ---

I dont remember (im not at home right now). But maybe base it on this, since its very popular with the arduino: [https://www.sparkfun.com/products/9056](https://www.sparkfun.com/products/9056) ---

In your link, there is a “byte-to-bits” node. I cant seem to find it anywhere. Where do I find it? Thanks ---

And another thing: It would be nice, if the “read4067” node, had distinct outputs for each input (0-15). Right now, it only has 1 output, the VAL. Maybe even a “combined VAL”, and “Out0 VAL”, “OUT1 VAL”, “Out2 VAL”, etc etc. This is only a suggestion of course:) ---

Right now, it only has 1 output, the VAL. Maybe even a “combined VAL”, and “Out0 VAL”, “OUT1 VAL”, “Out2 VAL”, etc etc. This is only a suggestion of course:) When I did, I thought about using the same entry selector to activate each internal process by taking a single exit. But it’s a good idea, I’ll keep it in mind. Only now there is a limitation of outputs to do it in C ++, I’ll see what I can do ---

THANKS:) In my specific project, i want to take the 16 inputs, and store them and possibly manipulate them, so having access to each one of them woul be amazing:) ---

Had a look at your exmple file, and i cant seem to find the bytes to bit node in it?🙂 Just whenever you have time. No stress! Another thing: Using your latest node, i get an error: ![2](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/748a58d7d8411bd3be726f150524d895b7fb7ed7.png) ---

Yes, the nodes on the left are just left-overs from som experimentation:) And found the bytes to bits. Will try later today. (away from my arduino. ---

version library is 3.0.7? try again I tested it in a clean installation and just downloading the library, and I did not have that error, tested in 2 PC without error ---

Very weird. Yes 3.0.7 I just updated it again, and i get the same error. ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/a1fee5e58985e6d0fc6ec692f3da5d4810b9aa1e.png) Weirdness. Im in the newest XOD version. v0.25.3 (2018-11-22) This is the code for the gate: ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/7c32a9689c297ba3a404f26f3660b815aadc00f5.png) ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/f38c8b4c8af20c01c1d60e4a2dde6657a929c73e.png) ---

oh, fix OUT1 gate(number) to C0, OUT2 is an error, maybe of its installation, because here it does not happen [Previous page](https://forum.xod.io/t/multiplexing-with-74hc4067/1302.md?page=1) [Next page](https://forum.xod.io/t/multiplexing-with-74hc4067/1302.md?page=3)
