Open Macro Input is about allowing actions based on open input ways... So Arduino, or else, is a must.

This file extension is my way of doing it.

This file extension allow you to define a serial port to listen. (Serial port can be USB or Bluetooth on Window)

The requirement is that your Arduino communication through port in a specific way.

For Example:

#01010|2492\n

Format:

#Digial Inputs from 0-1|Analogic Inputs from 0-9
#01234|0123\n

The example is saying:

• that the boolean value at the index 1 and 3 are considered as active on the five used
• all analogic value are used but the index 3 is highly active on the four used

Note: we are talking about index and not "pin". My aim is to have abstraction between hardware and software. For example:

• the pin 2 and 4 could be creating the index 0
• the pin 1 and pin 3 could be creating the analog 2
• every seconds you could be switching index 1
• ...

Note: why is it compressed ? Bluetooth and USB has a bandwidth that can be small. The impacts of none compress data:

• less devices can be connected by Bluetooth
• the time between "frame" become longer
• and you slow the reading program thread.

For example, here is what I use with my "four buttons foot board"

Send by the Arduino #0000|

Translation in the OMI software

<?xml version="1.0" encoding="utf-8"?>
<AnalogDigitalCompressConfig>
  <PortConnections>
    <PortConnection portId="20" patternName="Footboard" />
  </PortConnections>
  <AnalogDigitalCompressPatterns>
     <AnalogDigitalCompressPattern name="Footboard" docUrl="">
      <digit index="0" label="FootRD" />
      <digit index="1" label= "FootLT" />
      <digit index="2" label= "FootRT" />
      <digit index="3" label= "FootLD" />
    </AnalogDigitalCompressPattern>
  </AnalogDigitalCompressPatterns>
</AnalogDigitalCompressConfig>

The code will register the serial port number 20 and convert the index 0-3 to boolean named FootRD-FootLT that you can use as easy as other input like keyboard.

Basic example of what it can look like on Arduino in quick code version:

 int buttonCount =4;
 int buttonPin[] = {33,35,37,39}   ;

void setup() {
  Serial.begin(9600);
  for(int i=0; i< buttonCount;i++){
      pinMode(buttonPin[i], INPUT_PULLUP);
  }
}

void loop() {
  Serial.println("");
  Serial.print("#"); 
  for(int i=0; i< buttonCount;i++){
    int v= digitalRead(buttonPin[i]);
    Serial.print( v==0?"1":"0");
  }
  Serial.print("|");
  delay(10);
}
