  • GPIO Set PortFIlePointer

    Hello Support,


    i have following Problem by set the dio port:
    - My DIO Port is working but now i have the Situation that i just want to set port 3. I am using the setFIlePointer Methode but it doesn't work and i think i do something wrong.


    Reg Settings:
    reg open \Drivers\BuiltIn\DIGITALIO
    reg set val Port DWord 0
    reg set val Index DWord 0
    reg set val UseAsIO hex fc,01,fc,01
    reg set val DataDir hex fc,01,fc,01
    reg set val DataInit hex 00,00,00,00

  • UART COM Settings

    Small Question:


    is it possible that Baudrate 1200 (8,N,1) is not supported? 19200Baud(8,N,1) works perfect, but it seems that the RTS/CTS Signal doesn't work for 1200 baud. The received Byte size is not right in length and i got a lot of CRC mistakes? Note: I'm working with RS485 Converter

  • Import SSL Cert

    ok i got it!!!


    That works for self signed certs:
    1. use the code on top to Import pfx file in my certs
    2. now you have an unsigned key, although you have import a root cert
    3. i don't found a way to sign the cert, but that is not important in embedded, beacause it is isolated anyway. Forget the root cert!
    4. set the cert like that (vb.net):


    cc = New ClientCredentials
    cc.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindBySubjectName, "subjectname")


    and now tell the System to trust the unsigned certs:


    create class:


    Imports System
    Imports System.Net
    imports System.Security.Cryptography.X509Certificates


    Public Class TrustAllCertificatePolicy
    Implements System.Net.ICertificatePolicy


    Public Sub New()
    MyBase.New()
    End Sub


    Public Function CheckValidationResult(ByVal sp As ServicePoint, ByVal cert As X509Certificate, ByVal req As WebRequest, _
    ByVal problem As Integer) As Boolean Implements ICertificatePolicy.CheckValidationResult
    Return True
    End Function
    End Class


    and put following under the set cert method:


    cc = New ClientCredentials


    cc.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindBySubjectName, "subjectname")
    System.Net.ServicePointManager.CertificatePolicy = New TrustAllCertificatePolicy()



    thats it!

  • Import SSL Cert

    i found a code in vb.net where it is possible to Import by pinvoke to set pfx in Windows store. when i try it the key appears in list and i can find the key via


    cc = New ClientCredentials
    cc.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindBySubjectName, "wcf.gon-tech.com")


    but the Server does not accept the key. on Desktop it works! maybe it helps you to solve the problem

  • Import SSL Cert

    hmmm ok, but i don't think for wcf Server. i think it makes no difference with which tool I create the certificate, perhaps they will do it through other ways.


    I'm using the offical MS way for Transport security and basic http binding:
    http://msdn.microsoft.com/en-us/library/bb629363.aspx


    i tried a lot of tricky methods, but no success. other Forums says that it is just possible over Windows cert store!

    http://stackoverflow.com/quest…net-compact-framework-3-5


    nobody could solved the Problem

  • Import SSL Cert

    ?????


    I searched for other ways to Import it, but in .net compact Framework it is just possible to use the way over the Windows Cert Store.


    // Specifies the X.509 certificate used by the client.
    ClientCredentials cc = new ClientCredentials();
    cc.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindBySubjectName, "testuser");
    parameters.Add(cc);


    When i try to Import it via byteArray, it is not possible in compact Framework , just in Desktop Framework. Other ways ????
    We need secure connection to Server, to finalize out project!!!!

  • Import SSL Cert

    I tried to Import a SSL Client Certificate on ARMStone A5 (WEC2013) and i have following problem:


    First Way (GUI):
    - I tried it over the 'System Control' way by GUI and i could successfully implement my Root Cert in 'Trusted Authorities'
    - after that, i want to implement my Client Cert (pvk) im 'My Certificates', but after i type in my Import Password the key does not appear in list and it doesnt work in application
    Second Way (ndcucfg):
    - when i try it over ndcucfg, i just got a sequenze of that:
    Please enter Password:Please enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter passwordPlease enter password......


    and it is not possible to enter


    ????


    Note:
    First I debug the code and the cert on a Desktop System where it is working perfect. Iam absolut sure that everything is right with code, Cert and Connection to Server!!!!
