Hi everybody!
I use a PCI6052E-Card and xPC target system.To control a ac-motor, I generate a 3phase-pwm signal, synchronized by a main clock. The pwm signals are symmetric. I use the falling edge of the main clock to do this. Now I would like to measure the current with a DCCT. To reduce the noise, I will trigger the measurement at the falling edge of the main clock.
Theres no driver for an xPC-system, so I need to program in C in Register Level. I know the DAQ examples. I have the DAQ-STC Reference and the PCI-E-Series Manual. In Simulink exist only one block to use the AD on a PCI6052 Card. I try to modify it, because I think it is a good basis.
I used the main clock as an (a) external convert signal, (b) an external convert&start signal (single wire acquisition) but I got nothing.
What I need is to to scan/sample the ADC for one time, every falling edge if my main clock.
Thanks,
René
