Part Number: DAC81416-08EVM
Other Parts Discussed in Thread: USB2ANY

Tool/software:

HI,

I have a setup that uses the DAC81416EVM connected to a PC through the USB2ANY card.

I want to be able to control the DAC outputs using my own software script ideally using Matlab or Python.

What kind of API are available to accomplish this? (I have seen on the forums that there is some SDK for the USB2ANY card but I couldn't find where to download it)

Can you provide some sample code that shows how to accomplish it?

I also noticed that the software that comes with the EVM board has some ability to run Python scripts (not exactly what I need but still interesting) but it complains that it can't find the Python installation although I made sure the correct version requested (Python 2.7) is installed and on the default path. Can you explain where does the software looks for the Python executable, and maybe provide again some sample scripts.

Many thanks,

Yohai

Hi Yohai,

We don't have the python/matlab based HW and EVM GUI setup and we also don't have a sample code for the same.

Here is what you can do -
1. If you have python/matlab based SW driver for USB2ANY. You can create the SPI frame as per data sheet and do the read/write operations.
2. If you have any module which can generate SPI patterns like FTDI, FPGA or anything else; bring out these SPI outputs and use the J8 connector pins for the connections and do the read/write operations.

Thanks,
Sanjay

Hi Sanjay,

Thank you for the quick reply.

I have seen on the forum that there some SDK available for the USB2ANY can you point me to where I can download it?

Thanks,

Yohai

Hi Yohai,

It is my understanding that we do not share the USB2ANY SDKs. It looks like this e2e thread shares a download so you can give it a try, but the DAC team likely will not be able to support it if you run into issues: TMP117EVM: USB2ANY SDK required to safely work with the module - Sensors forum - Sensors - TI E2E support forums

You can look into the USB2ANY Explore tool available on the product page as well: USB2ANY Evaluation board | TI.com

Best,

Katlynne Jones
