New project - MSFS C++ USB interface

[Demon]

Yup, we should be able to find an answer to a question on just about any software issue today. Oddly, I'm starting to notice a trend of websites posting "relevant information" without going into the exact answer. I'm starting to think that web traffic (money for ads) is starting to dilute our source of information. And then the forums of egos arguing with each other, and not one of them give a complete code answer to the original question. It's taking a surprising amount of times on some issues; like the sheer volume of C# links popping up for C++ searches; driving me bananas.

I had a serious lag issue with my USB generated code when I'd read variables from the MSFS SDK. So I started a new program from scratch, no USB, made just to read the Engine RPM and nothing else. Then I compared it with SimVar Watcher; it's the tool distributed along with the SDK to doublecheck our work. Turns out I had to add a delay feature to run beside SVW at full speed (I got extra practice on string manipulations and tweaking a Timer on the fly, so not a waste of time).

This is with a 1ms delay timer on my program during max acceleration:




I had to slow down to 5ms to be right at the same speed as SVW also during max accel:




So I'm happy. At least I know that now I can run at an acceptable rate of speed. I have a theory why my code bogged down before, need to do another test.
