1. Then just don't do that
2. You would have to do that with Message port and then probably a Mega2560.
3. That's indeed a bit strange, those should be equal.
4. I've discussed the sorting with Corjan a couple of months ago. I'm not sure what it was, but it wasn't that easy. So I don't think this will change, at least not soon.
I wanted to make one of these. Hence the questions. Did not want to reinvent the wheel.
So if the RPi can use 8x9 matrix then I will redo it for the RPi 3.

The Pi is for the screen? And then an Uno attached to it for the IO?
Ralph,
Yes you got it spot on. Unless you know a better solution. I know the solution but Corjan will not play cricket with me.
I will use the Pi for the screen and big button matrix, and the UNO for small button matrix, led's and ADC output for the BRT pot.

Afternoon Keith,
Just sling a bank of these on. Use for any I/O purposes
16 I/O ports each chip. SOIC or DIL. SPI or I2C, the world is your crab.
On the I2C (the S version) you can have 8 devices on one bus. I think that will be enough for you
Dirt cheap !. I used 4 in a commercial project about 10 years ago. Rather neat little unit.
hmm, this is nice and cheap and looks superbly made.
Comes with cable and connector, very nice. Also have code examples for Arduino and pi, although the arduino libs are already superb. https://thepihut.com/products/mcp23017- ... ZnEALw_wcB
@jph Yes that can be done. But needs some competency.
I am looking for solutions for noobs.
AM is a wonderful flexible tool and for those not so clued up on coding and technical stuff, could be a gift from ones believer.
Whilst MSG Port is a good thing, it is directed at 0.009% of users. If users had the ability to use MSG port then they would not need AM. IMHO of course.
Peeps want to download a design, hash up something with what the can afford and not worry too much on the coding aspect.
Many peeps are producing hardware instrument and submitting to the store.
We have to be careful that those instruments work on all boards. The current situation is that the console accepts a 16 x 16 array where the software does not.
KISS is the goal so that all can benefit. That is what I try and steer the SI guys towards.
