Im using ULDAQ on MacOS Sonoma.

The following are the messages: (d_in.py)

Please select a DAQ device, enter a number between 0 and 0: 0

 

Connecting to USB-DIO96H - please wait...

Hello @vonQ.

The MCC Universal Library for Linux has not yet been tested with macOS Sonoma.  Stay tuned for updates.

Which MAC device are you using and its specs?

Does your USB-DIO96H device work with previous macOS releases and/or Windows OS, to rule out a hardware issue?

Regards,

Hi,

My Mac M2 OS Sonoma is used for development, I have E-DIO24 that is working fine with it.

On our deployment we used Ubuntu 20.4, we get same error on USB-DIO96H, no errors on E-DIO24.

We are migrating our Windows App to Web using UL for Linux.

We have a lot of USB-DIO96H in use same error occurs on Mac/Linux.

USB-DIO96H firmware is on version 2.4

Hello @vonQ.

Have you always seen an error with all your USB-DIO96H devices, when using UL for Linux?

Do you have the same error(s) with the USB-DIO96H devices, when using a Windows OS?

Firmware version 2.05 is available for the USB-DIO96H device, using the following link.

https://digilent.com/reference/daq-and-datalogging/firmware/start

Are you using the current version of UL for Linux C API posted on GitHub?

https://github.com/mccdaq/uldaq

Afterwards, did you install the current uldaq Python API package?

https://pypi.org/project/uldaq/

Hello @vonQ.

I was able to successfully run the uldaq example, d_in.py, with a USB-DIO96H on a MacBook Pro (M1) with macOS Sonoma 14.1.2.  Additionally, I tested the USB-DIO96H with the uldaq example and a Raspberry Pi 4B module running Raspberry Pi OS Bullseye; no ULError.DEV_NOT_FOUND error detected.

Are you running the example from the Terminal application or a different application?  Please provide screen captures showing commands and errors.

Please test your USB-DIO96H with a Windows OS system.  Install InstaCal on the Window OS system followed by the mcculw API package.

Regards,

Fausto

Hi @Fausto,

I have run InstaCal on Windows and successfully upgraded the USB-DIO96H to firmware 2.05.

I have tried uldaq versions 1.2.1 and 1.2.3 as per instruction, still same error.

Please see the screenshots of my testing.
