Wie kann ich ereignisgesteuerte Stopuhr programmieren?

I have the one with the sequence now, so I can see what you've done.

You need to put the detection sequence in a separate while loop. The code is executed once and then waits for the burst loop to exit before it can execute again.

Thanks,

I try this and tell you fin taht was for that Problem the solution.

Thank you

It seems that it doesn't work. Please kann you send a Printscree or the vi? It is maybe possible that I didn't understand you rightly.

Note the Stop button is now set to switched instead of latched, it should be reset before each start of the FPGA code.

 If this doesn't work you can try to catch the DIO on line 1 instead of line 0, on which you output the signal. Wire DIO0 to DIO1.

Ok,

i understand you correct. I have tryied this but it didn't done. What can also be wrong?

Martin

[andre.buurman@carya]

Did you also try to option with DIO0 and DIO1?

Could have something to do with simultaiouly reading and writing to the same DIO from multiple loops. The DIO has to be put in a read state or write state and they need to be interlocked. Maybe try a different DIO port instead of

DIO1. Configure port 0 as ouput and port 1 as input.

Sorry I can't understand the las tipp. Can you explain more? Should I wire with a hardware wire from DO0 to DO1? please send me your vi screen and tell me how could I try to solve my Problem!

Martin

[andre.buurman@carya]

Yes hardwire DO0 to DI1 on ternimal box. Detect pulses on DI1 in detection loop.

Hi,

this variation is better. The numericdisplay tdon is changing the value during the signal is send out on DO0. Now the Problem isn't solved, because the tdon is alway to long on my scope the tim is roundabout 200µs an in the vi displays thousends of µs. What is wrong? how musst I measure the time in the vi? I think I measure the time howlong the sequenz take and not the tdon of the signal!

Martin

Thanks for the helpful tipps.

I want  top the meassure if the  voltage on the AIO is from 5V gone to on 3V. For this I set the theshold on 8200 is this correct? With this settings the tdon time is 4 µs this is to short. The scope displays c.a. 200µs.

What can I try?
