MuxShieldDigitalIn

Using Arduino Programming Questions
#1

I have this sample code for the Mux Shield II and I want it to read through all 16 input on IO1, all 16 input on IO2, all 16 input on IO3. one at a time and only once. Then print all 16 inputs for each IO once.

Like: IO1 analog values: 1 1 1 1 1 1 0 0 0 1 0 1 1 0 1 0 1
IO2 analog values: 1 1 1 1 1 1 0 0 0 1 0 1 1 0 1 0 1
IO3 analog values: 1 1 1 1 1 1 0 0 0 1 0 1 1 0 1 0 1

//This example shows how to use the Mux Shield for digital inputs
#include <MuxShield.h>

//Initialize the Mux Shield
MuxShield muxShield;

void setup()
{
//Set IO1, IO2, and IO3 as digital inputs
muxShield.setMode(1,DIGITAL_IN_PULLUP);
//use DIGITAL_IN in place of DIGITAL_IN_PULLUP if internal pullups are not needed
muxShield.setMode(2,DIGITAL_IN_PULLUP);
muxShield.setMode(3,DIGITAL_IN_PULLUP);

Serial.begin(28800);
}

//Arrays to store digital values
int IO1DigitalVals[16];
int IO2DigitalVals[16];
int IO3DigitalVals[16];

void loop()
{
for (int i=0; i<16; i++)
{
//Digital read on all 16 inputs on IO1, IO2, and IO3
IO1DigitalVals = muxShield.digitalReadMS(1,i);
_ IO2DigitalVals = muxShield.digitalReadMS(2,i);_
_ IO3DigitalVals = muxShield.digitalReadMS(3,i);
* }*_

* //Print IO 1 values for inspection*
* Serial.print("IO1 analog values: ");*
* for (int i=0; i<16; i++)*
* {*
_ Serial.print(IO1DigitalVals*);
Serial.print(’\t’);
}
Serial.println();
}*_

Does your code really have italics in it?

Now, read the stickies at the top of the forum - the ones you were supposed to read BEFORE you blundered in here, and try again.

OK, Sorry!!! I am new to this, and to coding all together but I have did some change to the code and I have it printing to serial like this:

IO1 analog values: 1111111111111111 IO2 analog values: 1111111111111111 IO3 analog values: 1111…

Printing once.

Can’t seem to get the code to print in list form?

//This example shows how to use the Mux Shield for digital inputs
#include <MuxShield.h>

//Initialize the Mux Shield
MuxShield muxShield;

//Arrays to store digital values
int IO1DigitalVals[16];
int IO2DigitalVals[16];
int IO3DigitalVals[16];  

void setup() {
    //Set IO1, IO2, and IO3 as digital inputs
    muxShield.setMode(1,DIGITAL_IN_PULLUP);
    //use DIGITAL_IN in place of DIGITAL_IN_PULLUP if internal pullups are not needed
    muxShield.setMode(2,DIGITAL_IN_PULLUP);
    muxShield.setMode(3,DIGITAL_IN_PULLUP);

   Serial.begin(9600);
   delay(2000);

  for (int i=0; i<16; i++)
  {
    //Digital read on all 16 inputs on IO1, IO2, and IO3
    IO1DigitalVals[i] = muxShield.digitalReadMS(1,i);
  }  
  
  //Print IO 1 values for inspection
  Serial.print("IO1 analog values: ");
      for (int i=0; i<16; i++)

  {
    Serial.print(IO1DigitalVals[i]);
  }
    Serial.print('\t');
    delay(500);
     
   for (int i=0; i<16; i++)
  {
    //Digital read on all 16 inputs on IO1, IO2, and IO3
    IO2DigitalVals[i] = muxShield.digitalReadMS(2,i);
  }  
  
  //Print IO 2 values for inspection
  Serial.print("IO2 analog values: ");
    for (int i=0; i<16; i++)
  {
    Serial.print(IO2DigitalVals[i]);
  }
  Serial.print('\t');
  delay(500);
  
    for (int i=0; i<16; i++)
  {
    //Digital read on all 16 inputs on IO1, IO2, and IO3
    IO3DigitalVals[i] = muxShield.digitalReadMS(3,i);
  }  
  
  //Print IO 3 values for inspection
  Serial.print("IO3 analog values: ");
    for (int i=0; i<16; i++)
  {
    Serial.print(IO3DigitalVals[i]);
    
  }
  Serial.println();
  delay(500);
  exit(0);

If you want to put each on a separate line, put "Serial.println();" instead of "Serial.print('\t');" between them. The '\t' is a tab character. The .println() sends a newline character to start a new line.

What kind of list? Something like a table

IO1             IO2             IO3
11010011        10100101        00000000

Thanks I appreciate the help.
