#3615

Hello

I am current using the Arduino IDE with a Teensy 4.1.

When I add more than 3 edit widgets to a page that have input_type: int there is more than 200 bytes and I get errors.

Normally looks like this:

53 54 3C 10 71 0 F 6F 72 61 6E 67 65 43 6F 75 6E 74 0 0 0 0 3E 45 54 E6 5 legitimate
53 54 3C 10 71 0 E 67 72 65 65 6E 43 6F 75 6E 74 0 0 0 0 3E 45 54 9D 53 legitimate
53 54 3C 10 71 0 D 62 6C 75 65 43 6F 75 6E 74 0 0 0 0 3E 45 54 94 6A legitimate
53 54 3C 10 71 0 F 62 61 74 63 68

I’ve increase the [RX_LEN] in stone.h to 300 but it seems to be on the HMI side.

Any suggestions?

Were these four lines received together at the same time?

It looks like the first three lines get three receptions, and the fourth line somehow gets half?

RX_LEN in stone.h is a legitimate length to receive a legitimate frame. If you want the legitimate data in front of the word “legitimate”, it’s a legitimate frame, so changing this is probably useless

Hi Bowei

I have hundreds of different buttons and functions that work fine.  The problem is only when I have more than 3 edit type widgets set to input_type: int on one page/window.  When the page loads it sends cmd lines you see above.  When it exceeds the 200 bytes it becomes truncated or the HMI is timing out.

Since I can increase the [RX_LEN] to 300, 400 ,500 and it does nothing to fix the problem I am assuming the the internal transmission buffer of the HMI is only 200 bytes.

Best Regards

You can try updating the firmware of the HMI, or you can record a video describing the problem,Because I figured if I received data like the above, the actual length might not exceed 200 bytes

Hmm, and my STWI series display does not send anything when loading a page with editing widgets.

Just got Version 1.1.6 This morning.  It fixed the problem.

Thanks

[Andrey]

#3629

O! I want version 1.1.6 too :))))
What version did you have before?

@Andrey

 

Did you try changing your settings from default input type of text to int?  It doesn’t send anything if its on text.

[Andrey]

#3628

Oh sure. I added an edit widget to the new window, changed its type to Int, set an arbitrary numeric value, and copied it 9 more times. When I switch to this window from the main one by pressing a button, I receive only a notification from the display about the button being pressed and that’s it.
That edit fields are indeed of type Int is confirmed by the fact that when entering a new value into them through the keyboard, only numbers are entered.

Problem is still there.  I’ve checked and double checked the transfer buffer on the HMI seems to be 200 bytes.

 

“The send buffer of the above two solutions is “STONE_TX_BUF”, with a size of 200 bytes. The send
implementation function has timeout processing. When the user continuously calls the send interface,
ensure that each Instruction can be sent successfully.”

How do I avoid overflow how long is the timeout?

#3638

Where is this quote from? And what display model do you have?

[Michael Forlong]

#3640

I found the solution to the issue:

Everything works fine until you encounter an Overflow.  An overflow would occur sometimes with functions that are time sensitive.  In order to avoid this you should use:

stone_recive_free();

Hence:

/* Text type data memory allocation function, dynamically created, not automatically freed */
/* The stone_recive_free() interface can be called to free memory when the user is finished using it
* If the user does not release the memory, the memory space occupied last time will be released before the next use

Hope this helps someone in the future

That’s why I prefer to write my own libraries, rather than using someone else’s 🙂 Often, writing your own library takes even less time than learning a third-party one. And most importantly – I understand how all its mechanisms work 🙂
