Hello Community,
i have now a myRIO with Labview 2013. I try to read a digital signal of a sensor on port DIO0 (C-Port). It works fine. The problem is that i don't know, how can i find the beginning (the SYNC Nibble) of the SENT- Frame and how does it works with the clock ticks/ clock time of the FPGA System (40Mhz). I don't understand the meaning of the clock time. clock ticks.
The next problem is to measure the time between falling edge to falling edge. Actually i can detect every falling edge of the SENT signal but i can't measure the real time between them. How can i measure the real time depending of the clock time of the FPGA system? The SYNC Nibble have every time 56 ticks. But how much time are the 56 ticks?
Best regards,
Basti
