Big thank you @oakdesign your new answer is clear and simple.
And thank also you for the share of F4SharedMem.dll !
I will clone the repository and retry to recompile the code once again.
Some reference value have changed. I will try to get the new way to getting data.
For instance, previously i used to create the thread :
falconReader = new Reader(FalconDataFormats.BMS4);
readThread = new Thread(readFalconBmsSharedMemory);
Now FalconDataFormats does not exist in the new context.
@airtex2019, i don’t think is also simple.
Tank you oakdesign
