PEAK-System Forum

Hi,

I am using a dual channel PCI express device to receive messages from a CAN FD device which transmits messages repeatedly. When I use PCAN-view to initialize the device everything works fine and all messages are received and displayed. But I am developing my own tool for that and ran into some ...

Hi,

Sorry for the delayed response, I implemented the timestamps similar to the example code that you sent. The QueryPerformanceCounter seems to have solved all my issues. Thank you very much for your help and advice.

I only noticed one small detail while running your example, the "Up time" in the ...

I tried using the performance counter, I wrote this snippet just to check if there is an offset.


var peakTime = TimeSpan.FromMicroseconds(timestamp.micros + (1000UL * timestamp.millis) + (0x100000000UL * 1000UL * timestamp.millis_overflow));

var uptime = new PerformanceCounter("System", "System ...

Thank you for your reponse and for spotting that my timestamps were inacurate in the miliseconds range.

But the accuracy in the milisecond range is not my main concern here. The big problem is the unpredictable behaviour of the pcan timestamp. It returns the wrong wrong time elapsed from the system ...

I am using Windows 10, C# and PCAN Basic API dll 4.4

I have software which needs to get the timestamp of the received CAN message. The timestamp should be the time measured from the initialization of the CAN interface. I understand that the TPCANTimestamp gives the time elapsed from the booting of ...
