B4R Question TM1637Display 7-Segment LED

[ralfkammel]

Hi,

I tried to produce a library for the TM1637 7-Segment display form avishorp@gmail.com

No success.

Does anyone have a functioning library or some code for me?

 

[Erel]

Is there any open source library that you are trying to wrap?

 

[ralfkammel]

Hi Erel

here is the link to the library . wrong link in the posting - sorry

Thanks, Erel,

but it does not work. see example...please

#Region Project Attributes
    #AutoFlushLogs: True
    #CheckArrayBounds: True
    #StackBufferSize: 300
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
    Public Serial1 As Serial
    Public Display As TM1637Display
    Public i As Int
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    Display.Initialize(2,3)
    Delay(1000)
    Display.Brightness=6
    For i=1 To 99
        Display.ShowNumberDec(i)
        Delay(1000)
        Log(i)
    Next
End Sub

I don't have this module so I cannot test it. In which way doesn't it work? Do you see the logs?

Are you able to run the C examples from Arduino IDE? Do they work?

 

[ralfkammel]

Hi again,

I ran the c example and it worked.

Library is OK in C!

I can see the logs running.

So i have to wait for someone with the module, many thanks Erel for the help.

Greetings from rainy Germany!

 

[Erel]

I've fixed an error. Please try the attached library.

 

[ralfkammel]

I am so sorry Erel,

the display stays dark, even with the new library.

 

[Erel]

Don't be sorry

Sorry for reviving such an old thread, but is there any update on this? I have some smaller 4 digit LEDs that work fine with the TM1637 library but I'd like to use larger ones that also appear to have decimal points (though whether they are functional or not is debatable).

Supposedly this library works with them:

You shouldn't post in this thread. The rTM1637 library was introduced after this thread was created.
