How to quickly verify if GPIO-to-USB is damaged？

Kelly Li72

The green light is on, indicating that the USB has been successfully connected, but it seems that the GPIO has individual damage. Is there an easy way to check whether the status of the GPIO is OK?

Many thanks.

Hi Leonard,

Thanks very much for your reply.
I found an old USB-to-GPIO(www.ti.com.cn/.../USB-to-GPIO)in the warehouse. I want to confirm whether the function of this tool is OK?
The USB looks OK, but I don't know how to verify the GPIO section. There is no device or EVM on my hand now.
would you please give me your suggestion?

Hello Kelly,

There isn’t a specific set of tests that I know of to test the full functionality of the SAA Adapter. However you can download our GUI and change some settings to see how it responds. First off if the GUI opens that’s an indication that there is some level of communication. I have also put together a post covering how to toggle the GPIO bits on the SAA with our device GUI that you can try out.

Please see this post, specifically the last post I made at the bottom:
