We are using PL section of the Zynq7000 to transfer data to another module b y creating a SPI IP Inside the PL. We want to know that the PMOD pins availvalble on the Zybo-Z710 board are using open drain or push-pull configuration ? Do they have something like a internal pull-up resistor ? Please let me know..

Hi guys, I am new to this Forum. I am working with LabVIEW, cDAQ, NI 9361. I am trying to acquire the Pulse Signal output from a Flow meter (Flow meter Output: Passive open collector, 30V, 250mA) using NI 9361 and cDAQ 9185. Initially I connected flow meter output +24 and -25 directly to an oscilloscope, I couldn’t see any pulse. And Just tried connecting to PFI0+- of NI 9361. My program is as attached below. The counter started counting but after few minutes it was displaying 0 forever. The pulse details are Pulse width: 100ms and Pulse value: 1kg Max Range of flow is 36000kg\h
