Direct numeral entry

// IRrx() is a function that returns a byte 0 to 20, 0 to 9 for numeral keys, 10 to 20 for others, 16 being the key I am // using for cancel (Pause)

// entrymode is set a 0 for 4 digit entry, 1 for 7 digit entry, in either case locations 0+ in that array

// the display is a dot matrix LED type, with a library that uses those commands, as well as the cursor, for I
// don't think that display supports one, but my blinking cursor (*) works fine.

void directentry(byte entrymode){
byte entryarray[7];// temporary array for numeral entry

myDisplay.clear();
myDisplay.home();

byte arraysize[2]={4,7};// (mute=time entry 4 digits, mode=date entry 7 digits)
byte array_pointer=0; // zero array pointer

while (array_pointer<arraysize[entrymode]){//open while, leave when array_pointer is above arraysize
   key=99; //no key received
   seccount=0;// timeout counter

  while (key>90){//open while, leave when key received(below 90)
    key=IRrx();// receive key
    toggle=!toggle; //toggle for cursor
    myDisplay.write(32+(toggle*63)); // write cursor
    myDisplay.setCursor(array_pointer);// set position back
    seccount++;// increment timeout seconds counter
      if (seccount>100){// exit entry if too long.
        key=16;// force key to be 16 (EQ on my remote, see below a bit)
      }
    delay(250);// delay fine here. Slow enough for cursor blink
  }// close while key

  if (key<10){// is numeral key, enter into array, display, increment array pointer
    entryarray[array_pointer]=key;
    myDisplay.print(key);
    array_pointer++;
  }

  if (key==16){//  EQ key/timeout, cancel entry
    array_pointer=arraysize[entrymode]+1;//make array_pointer big to exit while loop
  }

  }// end while array_pointer loop

} // end routine
