Is the shield compatible with Raspberry PI 3?

I have been trying to set multiple (n>=2) outputs at once but haven't been successful. Basically: muxShield.setMode(1, DIGITAL_OUT); muxShield.digitalWriteMS(1, 0, LOW); muxShield.digitalWriteMS(1, 1, LOW); muxShield.digitalWriteMS(1, 2, LOW);

Only triggers 2 outputs. It works fine when individual PINs are addressed. Is this a limitation?

This is the first shield I have purchased that had no headers to connect it to an arduino. I expected to have to do some soldering, but I didn't expect to have to buy separate headers. I'm sure that is my own fault and I probably could have figured it out if I looked more carefully. But I'm still disappointed.

It is not at all easy to tell what this product is capable of. I don't want to switch analog inputs INTO an Arduino, I want the Arduino to control the switching of audio inputs between other external devices. Can this be made to do that? I'm looking for some kind of analog switch or crosspoint switch shield where the only connection to the Arduinio is the switching control lines. I'd like to build a box that can control independent analog ins and outs, interconnecting them programmatically using the Arduino....

Are these stackable / daisy-chainable? I want to get MANY inputs into an Arduino - up to 500+. Would something like this make it possible? Or would this just be unreasonably slow (i.e. would it take forever to read all 500 inputs)?

You read my mind!! This is what I need to make my arduino controlled, web based fireworks launcher more reliable and compact... uhh.. I mean my model rocket launcher.. :-) Only 3 months to go 'till 4th of July you know!!

I wanted to use this multiplexer to control a few servos at a time and there was a lot of stuff on the web saying that it couldn't be done. The code below is for two servos. I've combined Adafruit Softservo with the mux shield code. If you have any improvements, please post here. Here is a video of it controlling 21 servos.

      {
        muxShield.digitalWriteMS(1, i, LOW);
        muxShield.digitalWriteMS(2, i, LOW);
        muxShield.digitalWriteMS(3, i, LOW);
      }

      writeMuxServo(1,0,90);  // reset servo
      delay(3000);            
    }

    void loop()  {

      angle += 30;
      if (angle > 180) {
        angle = 0;
      }
      digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
      writeMuxServo(1,0,angle);  // tell servo to go to position
      writeMuxServo(1,1,180-angle);  // tell servo to go to position
      delay(2000);                      
      digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
      delay(1000);
    }

Can this be use with the arduino mega 2560 r3 and if yes how many analog ports would it have then?

Once I soldered the headers on and installed the library it was working right out of the box correctly except that all of the information it was returning was garbled. The default baud set in their examples (contained in the library zip) was 28800 and when i increased it to 38400 or 57600 it then became perfect. (arduino uno R3)

I am using it for 48 analog inputs, and you must ground all unused inputs or they will transmit meaningless data.

Hi. I'm an uber-noob. Are folks familiar with the johnny-five project? A javascript firmata based Arduino framework...it's cool. I wonder if I can use this mux shield along with johnny-five? Sorry for the probably stupid question.

Hi

Please help resistive 7x10 matrix sensing Sample program we could share with me how to read the data matrix

I have two questions.

Does anyone know if the arduino Library works with the Mux Shield Version One.

I am having trouble running the digital example on my Leonardo. The analog example works fine but digital input does not show any change when the button is pressed. I have the Ground and I/O connected to a button. Am I missing something other then a button? I also tried to connect the 5v and I/O to the button still no change.

Can anyone tell me when to use a shift register and when to use a MUX? I think I understand how they both work. It seems to me that a MUX is faster and better for most purposes.

How much current can each output support?

I'm in a position where I need just a few more inputs. I'm building a midi xylophone and I want at least 4 octaves, which would use all 48 inputs, but I need some control components as well (octave shift, modulation, etc). Is there any alternative to this that I can use, or something I can add to this?

You can still get more I/Os from an Arduino mega, but I guess they're not ALL analog...

Worth to mention The Mux Shield uses Arduino digital pins 2, 4, 6, 7, analog input pins A0, A1, A2, and optionally uses digital pins 8, 10, 11, 12.

We've all blown a pin on our Arduino through bad soldering, misplaced wires, forgetting a resistor, or something of the sort. When that happens on this shield, do multiple pins "die"? Additionally, can I attach this to my Arduino that has lost a pin, and get more pins back? How many pins will be useless if my Arduino is one pin short?

This will compact my DCPU-16-on-Arduino w/30-pin RAM down from a Mega to a regular Uno or Leonardo. Nice!

All CMOS devices are type HC, not HCT, so 3.3V control signals would be near the minimum spec value for recognition as a logic "1". It would probably work, but temperature and unit-unit variations could cause mysterious errors over a population.
