Hello NI Community,
I’m trying to capture UART data (character "A" = 0x41, 8N1, 115200 baud) from an STM32 board using the PXIe-6571 in LabVIEW 2020 with the NI-Digital Pattern Driver (version 18.0). I’m using a modified version of the niDigital Capture Waveform VI example, but I’m consistently reading all 1s (or no data in simulation mode) instead of the expected UART frame [0, 1, 0, 1, 0, 1, 0, 1, 0, 1] (start bit, D0–D7 LSB-first, stop bit).

You need to save your code to version 2020. You can do this by going to save for a previous version in the file menu.

i tried saving as 2020 version and run it with PXIe hardware?, its not working...

We do not need for you to run it. We need you to post it here as 2020. Most of us are not using LabVIEW 2025. This way we can look at your code and help.
