I am writing program for counting the TTL signal input to PCI6036E board.But I don't know what counter in the labwin/cvi library should be use:GPCTR,CTR,or ICTR?
When I use CTR,or ICTR,the "error" shows:the device
doesn't support the action. when I use GPCTR,the "error" is: no setup has been performed for the resource,or some resource require a specific ordering of calls for proper setup. Another question is: the TTL signal should be connected to PFI3/GPCTR1_source pin on the PCI6036E board?
