Sending CAN messages with different timing in the same script

[RiccardoTa]

Hello everyone,
I need help understanding how to write this script in PCAN-Explorer 6:

Basically I need to send two different CAN messages, one for communicate with a board every 250ms and one to pilot a load every 4 seconds.
Something like this:

for x times:

Message 1
ID 1
(data)
wait 250

Message 2
ID 2
(data)
wait 4000

These two messages need to be sent in the same macro, in "parallel".
I'm new in writing macros so I was thinking on how to do it without getting stuck in the "wait" statement of the one that last 4s.
Any ideas? Can I create two different sub in the same macro and then a third that call the two with their specific timing?
I hope my request is clear,
I'm available for more information,
thank you in advance for your response.

Hello,

That's not possible in a standard Macro,

you could use a VBS Macro and use a rudimentary timer implementation:

Code: Select all

Sub TimerInstance()

Dim startTime, currentTime, elapsedTime
startTime = Now() ' Store the starting time

Do
    currentTime = Now() ' Get the current time
    elapsedTime = DateDiff("s", startTime, currentTime) ' Calculate the elapsed time in seconds
    
    ' Perform actions based on elapsed time
    If elapsedTime = 2 Then
        PrintToOutputWindow "Performing Action A (2 seconds)"
    ElseIf elapsedTime = 4 Then
        PrintToOutputWindow "Performing Action B (4 seconds)"
    ElseIf elapsedTime = 8 Then
        PrintToOutputWindow "Performing Action C (8 seconds)"
    End If
    
    ' Stop the loop after 8 seconds
    If elapsedTime >= 8 Then Exit Do

    Wait 500 ' Sleep for 500 milliseconds to avoid using 100% CPU
Loop

End Sub

Instead of just printing to Output you could send your messages at these checks..
