Access violation at address 0000000002CF5E0F in module 'IQANdesign.exe'. Read of address 00000000000000A8.

I am trying to use externals to break my project down into modules. As I am adding these modules in to the main project, I keep getting this error.  Once it occurs, the entire project file is corrupt and I get the same error every time I try to open it. I am stuck.

Hi,

Would you consider adding most and least significant bit indexing as native IQAN functions? Presumably it could be efficiently implemented using either instructions native to the controller, or in any case using de Bruijn.

Example: lsb_example.idax

Building the GUI with the latest version and I yet to be allowed to ungroup a group.

When IQANdesign does not provide a native function/operation, such a function/operation could be implemented in an external library, for repeated use in application logic.

Currently, the benefit of implementing the function in an external library is that any future change of said function/operation would only have to be done once, which is great.

But, would it not be possible to also save memory? I.e. could it be possible that multiple instances of the same external library function group would only be instantiated once in application memory, even though it is called multiple times per cycle?

(Unrelated to the topic, but related to the origin of the topic, do you have any plans to introduce native functions for most- and least significant bit indexing? E.g. using de Bruijn multiplication/lookup tables would be so much cheaper if done natively.)

Thanks!

I´m looking for the 23-24 October 2024 IQANdesign Online Training but can´t find where to register.

Please if you can help me.

Thanks

Hi,

I have imported from a dbc some generic CAN frame with mux. Each mux in each frame generated have the same value: 0

Moreover, the frame with the real mux value of "0" is not imported.

Is this bug known?

The Ethernet measure terminates 1 out of 5 times when I unplug a 60Hz signal from a PCNT channel on a MC43FS I am running IQANdesign 5.03.14.5040. I am aware this sounds like something in my hardware; however, two things make me question that.

1. The problem seems to have gotten worse as I add complexity to the function group that uses the input.
2. If I edit the function group to use a PCNT channel that is not connected to the problematic input, the problem goes away. This points to software because IF this was a hardware problem caused by the input disconnection somehow causing a hardware issue that gets into the hardware of the Ethernet signal THEN I would expect the same action to cause the same problem going into an identical input.

I have not been able to replicate the problem using a much slower input signal that I am generating in a slightly different way. However, the levels of the signal are the same.

I am suspicious that the high-speed bouncing causes the input to do something strange that the causes the firmware a problem possibly by exceeding the maximum input frequency.

Is it possible to send multiplexed j1939 message? I only see this option in Frame IN, not in Frame Out

Hi,

i make some programs on Parker Iqan 6 sometimes, especially, for mobile and crawler cranes.

I'm finalizing a program for automatic telescoping system,

but i'm struggling with the function "inside" used with Qcode.

Any assistance please ? I don't know what to write after "inside", to be honest
