possible threading issues with pmdg cdu data refresh

[Jason Fayre]

Hi Paul,

In our Talking Flight Monitor product, we are running into an issue with reading CDU data. There are a few circumstances where CDU data might need to be pulled by two parts of the software at the same time.

One part is running on the UI thread, and the other is running in a system.timers.timer thread. 

If we end up with a time where the data gets pulled at the same time, I get the following error in our debug log:

2021/07/24 16:24:04.516 - tfm.TFMMainForm.TimerMain_Tick - High priority instruments failed to read: Group '0~~PMDG_CDU~~' does not exist.

Any idea what might be happening or any way of correcting this?

 

Thanks!

Hi Jason,

The CDU class was using the same offset group between multiple instances. I've changed this so each instance will now have its own offset group. This should fix the problem.

Version 3.2.8 is now on NuGet.

Hi,

 

Thanks for your attention on this. A quick question: Will I need to change any existing code for the CDUs?

No, the fix was all within the dll.
