InterframeDelay

This parameter allows the configuration of a delay, with microsecond resolution, between CAN frames being sent within a PCAN Channel. Other applications working with the same PCAN-Hardware (for instance, a PCAN-View) are not influenced when configuring this delay.

This parameter can be used by applications that want to increase the separation time of consecutive transmitted CAN frames.

It is available since PCAN-Basic version 4.2.0.

• PCAN-USB: Channels Usb01 to Usb16.

• PCAN-PCI: Channels Pci01 to Pci16

This parameter is read/write. It can be configured and retrieved.

This is a numeric value in the range of [0...1023]) microseconds. If the value to be set is bigger than the resolution supported by the firmware, then the value is truncated.

The default value of the delay is 0, which means that this feature is deactivated. After configuring a value bigger than 0, the delay will be used until it is expressly deactivated (set to 0), or the Channel is disconnected, i.e., using the Uninitialize method.

Get: The PCAN Channel must be initialized before using this parameter.

Set: The PCAN Channel must be initialized before using this parameter.

The following code shows how to set a 20 microseconds delay between CAN frames within a USB Channel:

PcanChannel channelUsed = PcanChannel.Usb01;

if (Api.Initialize(channelUsed, Bitrate.Pcan500) == PcanStatus.OK)
{
    uint delay = 20;
    if (Api.SetValue(channelUsed, PcanParameter.InterframeDelay, delay) == PcanStatus.OK)
        Console.WriteLine($"A delay of {delay} microseconds between frames was configured for {channelUsed}.");
    else
        Console.WriteLine($"Error configuring a delay on channel {channelUsed}.");
    Api.Uninitialize(channelUsed);
}

Dim channelUsed As PcanChannel = PcanChannel.Usb01

If Api.Initialize(channelUsed, Bitrate.Pcan500) = PcanStatus.OK Then
    Dim delay As UInteger = 20
    If Api.SetValue(channelUsed, PcanParameter.InterframeDelay, delay) = PcanStatus.OK Then
        Console.WriteLine($"A delay of {delay} microseconds between frames was configured for {channelUsed}.")
    Else
        Console.WriteLine($"Error configuring a delay on channel {channelUsed}.")
    End If
    Api.Uninitialize(channelUsed)
End If

PcanChannel channelUsed = PcanChannel::Usb01;

if (Api::Initialize(channelUsed, Bitrate::Pcan500) == PcanStatus::OK)
{
    UInt32 delay = 0;
    if (Api::SetValue(channelUsed, PcanParameter::InterframeDelay, delay) == PcanStatus::OK)
        Console::WriteLine("A delay of {0} microseconds between frames was configured for {1}.", delay, channelUsed);
    else
        Console::WriteLine("Error configuring a delay on channel {0}.", channelUsed);
    Api::Uninitialize(channelUsed);
}
