Topic: Edit Field, Returns only value of zero


I am having an issue with the edit fields in my project... Simply put, no matter what value I enter into the field it returns zero. I have it configured as integer on both the project and in the Arduino sketch. Hardware is Arduino Nano and HC-06 with the app running on Galaxy S10.

I created a test project and a test sketch to reproduce the issue outside my production program and was able to isolate and  reproduce the issue.

This was working flawlessly at one time and then it stopped working when I updated the Arduino with a new sketch. I did some trouble shooting and replacing every bit of hardware and exhausting every other resource lead me here for your help. I am using the latest library.

I am hoping I'm not missing anything obvious because that wouldn't be the first time. I have been at this for days and can't figure it out.

I appreciate any input you can give and kind regards!

Re: Edit Field, Returns only value of zero


int val1 = atoi (RemoteXY.edit_1);

How does this even compiles ? atoi is to convert a char array into int, but RemoteXY.edit_1 is already an int.

I can only assume that in the remotexy editor, the type of "edit_1" was String, and then you changed the type to Integer.

And if you really want the type to be Integer, then I suppose you simply want to do this:

itoa(RemoteXY.edit_1, RemoteXY.text_1, 10);

A side note about improving your code, it's generally better to do something only when needed, instead of doing it every time loop() is run. You are constantly writing to RemoteXY.text_1 and RemoteXY.led_1_r, and it is more efficient (for your whole program, not for remotexy) to only do that when the values changed :

void loop() 
  RemoteXY_Handler ();

  static int16_t edit_1_previousValue = RemoteXY.edit_1;
  if (edit_1_previousValue != RemoteXY.edit_1)
    edit_1_previousValue = RemoteXY.edit_1;
    itoa(RemoteXY.edit_1, RemoteXY.text_1, 10);

  static uint8_t button_1_previousValue = RemoteXY.button_1;
  if (button_1_previousValue != RemoteXY.button_1)
    button_1_previousValue = RemoteXY.button_1;
    RemoteXY.led_1_r = RemoteXY.button_1 == 1 ? 255 : 0;
