TUSB9261 GPIO HID Commands

Jason Rush

Other Parts Discussed in Thread: TUSB9261DEMO, TUSB9261

I currently have a TUSB9261DEMO board and am in development of a design that uses the TUSB9261. I read in the datasheet there is a USB HID interface to configure/control the TUSB9261's GPIO; however, I have not found any documentation on the USB HID commands that control the GPIO interface. Can you please point me to the documentation?

Thanks,
Jason

Hello,
Please have a look at the below link, you should also set the HID enable option when burning the firmware using the Flash Burner tool.

Thanks Elias. I looked through the TUSB926x Flash Burner User Guide you referenced. It does have some USB HID commands defined, but none that appear to control the TUSB9261's GPIO. I saw references in both the data sheet and firmware change logs to a USB HID interface that can config/control the GPIO. Maybe this interface is documented somewhere else?

Hello Jason,
I asked to the FW engineer and it turns that you have to modify the source code to control the GPIOs, but we no longer provide the source code.
I think we are going to remove that from the datasheet.
I apologize for the misinformation.

According to this change log both v1.03 and v1.04 have HID commands for configuring and setting GPIO output.

Is this a feature that was removed?
