t0.txt value to send on serial


I have on display like a phone keypad, and I need to send via serial, a value of 9 numbers inserted on t0.txt with this, like 123456789

the numbers appear correctly on t0 , all 9 but when I pres first (1) this is already on serial send, and I need to send all 9 together , please help.


t0.txt=t0.txt+"1"   for 1

t0.txt=t0.txt+"2"  for 2  , etc.


no one help ?

First send a request to the display to retrieve the current value. Concatenate the values on your microcontroller and set the new value on the display.

I had the same.

First page init at display should delete the textfield if you want it empty

then your button 0 to 9 do it like you have:

t0.txt=t0.txt+"1" // for ONE button

Then you have an Enter-Button.

This button get the value of t0 so you have all values together and you can do with it what you want.

And keep in mind that you need to increase the field length (default max 10) txt-maxl.

Thank you for help, all is ok now !
  Another request please:
Now, if t0.txt has t-maxl 9 digits,

on next number pressed from keypad (the 10 digit to say),

 I need to switch to t1,txt to write value; how can  do this?

or, is another method to select t1.txt, and insert value with the same keypad , on the same page?

i think this should be possible with an if statement.

if t0 < 999999999

t0.txt=t0.txt+"1" // for ONE button


t1.txt=t1.txt+"1" // for ONE button

so that for every button

not sure if this will work in that way but it should.
