hi all,
I hope to create an ANSI C program to measure the angular velocity of an electric motor by an normal encoder and a NI PCI card pci6251. However, I find that this card can't support the property of "DAQmx_Val_Velocity_AngEncoder" which seems means that the NI SDK only support the function "DAQmxCreateCIAngVelocityChan" but not the function of "DAQmxCreateCIAngEncoderChan" for this device. Oh,so bad...
I hope to use the function of "DAQmxCreateCIAngEncoderChan" to measure the velocity. Because it seems more better than using "edge count" directly. But I don't know how to do it...
Has anyone can give me any tips or advice?
Thanks a lot!
Best Regards
