B4R Question stoped on "for each" loop

[Tayfur]

WEMIS D1 borad

I run sub of "Ayar_Kaydet_Yukle"

If b.Length>0 Then
        Log("#####START READ FILE SYSTEM####")
        Ayar_Kaydet_Yukle(b,False)
        Log("---FINIS FILE SYSTEMM--------")
        Delay(3000)
        Log("---<>>> AYAR yükleme tamam")
    Else
        Log("\\\\\\\ayar içieriği boş//////")
    End If

running code with like under below. and it stoped on "for each" loop

it s not contiune . it s like stoped.
I cant found problem. (I added logs)

Private Sub Ayar_Kaydet_Yukle (Buffer() As Byte,Kaydet As Boolean)

Does it hang if you comment all the code inside the For Each loop?

Add Log(StackBufferUsage) in the loop. What is the output?

#StackBufferSize: 1000

log is :1664 (after update 2000)

What is wemos buffer limit?

 

[tigrot]

The limit is free ram.

 

[Erel]

You still haven't answered my questions.

Does it hang if you comment all the code inside the For Each loop?

 

[Tayfur]

Only this loop. I tried first action for called ForEach Loop. and code run normally.

Now; Stockbuffersize solved my problem.
thanks

 

[Erel]

Another possible (and better) solution is to move all the loop inner code to a different sub. This way the stack will be released after each iteration.

That's an expert experience.
I will apply it.

It should look like this:

For Each s() As Byte In bc.Split(Buffer, "&")
 DoSomething(s)
Next

End Sub

Sub DoSomething(s() As Byte)
 ...
End Sub
