I get a real TTL-Signal from a resolver which is connected at the parallel port. From this parallel port I would like to read the frequency of the signal coming in. The resolver is connected at the parallel port at only one data pin and at a ground pin, without using a DAQ. (In past I used the InPort- Box of a example in developer zone, but it didn't work, because of the C-code) Thank you for your help, Bernd & Franz
