Need help on USB to UART converter Chip TUSB3410 for Interrupt base Transfer/endpoints

Hello Bhupendar,

The TUSB3410 can be configured for Interrupt transfers, you can find more information about how to configure the Output Endpoint1 Descriptor in the TUSB3410 Data Manual sec 11.3.4, You can find the Data manual at http://focus.ti.com/lit/ds/symlink/tusb3410.pdf

Unfortunately we don’t have an application that use this kind of transfers, but we can provide you the standard Firmware source code and the driver source code, expectantly that can help you on your design. If you want those source files, I can ask to Dan to provide you the files.

Best regards,

Roberto.

Thanks Roberto!

It will be a great help if you can provide us the standard Firmware source code and the driver source code for same.

Best Regards,

Bhupendar

Hi,

We have some more doubt on TUSB3410.

By going through the source code for TUSB3410, we didn’t find anything such as descriptor configuration for user. What we found is that UsbCfgGetDeviceDescriptor() function gets the configuration descriptor details, but we were not able to find how to configure the descriptor as ‘interrupt’ IN and OUT endpoints. Could you please provide about this configuration details.

Thanks & Regards,

Bhupendar

Bhupendar,

Your reference is to the driver side of the software.

Descriptors are handled in the device firmware. You need to look in the DevIoUSBCore.h file.

Hello DHarmon,

Thanks for the response. Another thing what we want is, we have changed the header file to make the endpoints and Interrupt type.

Now we need to build this. We see .prj file corresponding to the chips i.e. Fw_3410.prj for our case. Could you please let us know what IDE we should be using to rebuild

Firmware. Is it IAR workbench or Code composer studio.

Thanks.

Venkatesh

The firmware source was developed using the IAR Embedded Workbench v5.05. We have not ported this code to any other development environment. While, it should be able to be accomplished, we can not provide comments/support on the details of porting the code. We would recommend contacting the Compiler Tool Manufacturer to support the porting if you are using a different compiler than IAR.

Hello Dan,

We have project file ending with .prj( i.e. Fw_3410.prj) and others. We contacted IAR people, and they suggested that .prj files are not of IAR environment.

Is it possible to give us a build with IN and OUT endpoints as Interrupt type. So that we can try flashing EEPROM with the binary lately built. 

It is ok also ok if we get the binary(umpe3410.i51) directly with the changes.

Let us know how feasible it can be. Or any other ways to do this.

Thanks.

Regards,

Venkatesh
