Need Help for keyboard input

[ADVANCETOM]

Hey my problem is to change this in my Arduino sketch via the keyboard Input!

float seaLevelPressure = 1026.70; //edit to SLP for your location wanna also use for genie Input via Keyboard? //

i know i have to use the event handler , but im stuck here.

I have created a keyboard input 0-9 and a string Object

Hi,

This application note should help you understand arduino printing so string objects via keyboard:

http://www.4dsystems.com.au/appnote/4D-AN-00188/

This application note shows how to write a sketch for an Arduino program that prints characters on string object from keyboard object to create a simple Password Implemented Application

Hey my input from keyboard is working (Without dot i need also )and also print out.as keyvalue
So far so Good, but not changed in Arduino Teensy 3.1 for the new calculation and i dont know how to do that

My serial Printout from Serial.println(keyvalue[x]);
-----------------------------------------------------------------------------------
1
0
2
0
DONE
---------------------------------------------------------------------------------------------

keyvalue is a char and i wanna change to float sealevelPressure !


float seaLevelPressure = 1026.70; //edit to SLP for your location wanna also use for genie Input via Keyboard? //


But how can i do this after this process Arduino Teensy 3.1 should change this to a new calculate for Altitude!


And how can i use the (. dot) in code? with this code given 0-9 back and return works?


Need Help




Here is my code:

void myGenieEventHandler(void)
{
 
  genieFrame Event;
  genie.DequeueEvent(&Event);

  //If the cmd received is from a Reported Event (Events triggered from the Events tab of Workshop4 objects)
  if (Event.reportObject.cmd == GENIE_REPORT_EVENT)
  {
    if(Event.reportObject.object == GENIE_OBJ_KEYBOARD)
    {
      if (Event.reportObject.index == 0)                              // If keyboard0
      {
        temp = genie.GetEventData(&Event); 
        if(temp >= 48 && temp <= 57 && counter <=9)
        {
          keyvalue[counter] = temp;        // Receive the event data from the keyboard
          genie.WriteStr(3,keyvalue);                         //prints to String Object       
          counter = counter + 1; //increment array
        }
        else if(temp == 8)                              //check if backspace
        {
          counter--;
          keyvalue[counter] = 0;
          genie.WriteStr(3,keyvalue);
        }
        else if(temp == 13)
        {
          for(int x =0; x<counter ; x++)
          {
          Serial.println(keyvalue[x]);
            
            
          }
          Serial.print("DONE");
          //Serial.print(String(slp.toFloat());
         // char *keyvalue[x] = slp;
        // float seaLevelPressure = char keyvalue; 
                
          genie.WriteObject(GENIE_OBJ_FORM,0x05,0);
        }
      }
    }
  }
}

Ok the failure with .dot is char 110 but printed as an "n" is that right?

if(temp >= 48 && temp <= 110 && counter <=9) // Recognize only number 1-9 change this to 48-122 if Qwerty

1022n00 for 1022.00 ? im confused

[ADVANCETOM]

AHHHHHHHHHHHHHHH

i found a solution and it works

i set

double n;

in main loop:

float seaLevelPressure = n;


But this was the solution


n = atof (keyvalue); //printout 1022.00 great

Thats my GenieEventHandler routine for anybody who wants it to use




void myGenieEventHandler(void)
{

genieFrame Event;
genie.DequeueEvent(&Event);

//If the cmd received is from a Reported Event (Events triggered from the Events tab of Workshop4 objects)
if (Event.reportObject.cmd == GENIE_REPORT_EVENT)
{
if(Event.reportObject.object == GENIE_OBJ_KEYBOARD)
{
if (Event.reportObject.index == 0) // If keyboard0
{
temp = genie.GetEventData(&Event);
if(temp >= 48 && temp <= 110 && counter <=9) // Recognize only number 1-9 change this to 48-122 if using a QWERTY Keyboard
{
keyvalue[counter] = temp; // Receive the event data from the keyboard
genie.WriteStr(3,keyvalue); //prints to String Object
counter = counter + 1; //increment array
}
else if(temp == 8) //check if backspace
{
counter--;
keyvalue[counter] = 0;
genie.WriteStr(3,keyvalue);
}
else if(temp == 13)
{
for(int x =0; x<counter ; x++)
{
Serial.println(keyvalue[x]); //so you can see the captured string


}
Serial.println("DONE");

n = atof (keyvalue);
Serial.println(n);

genie.WriteObject(GENIE_OBJ_FORM,0x05,0);
}
}
}
}
}

Thank you ADVANCETOM.
even after all this time yours is the only example of using the keyboard object for Arduino I could find.
