TivaC as USB host for MSP430 Device

Nick Thomas

Afternoon all!

I have a requirement to interface a host Tiva part with an MSP430F55xx via the USB for testing purposes, the MSP comms package is already set and working with other platforms (windows based software etc) so I need to make my solution work with what I have (I know, sounds fun!).

The MSP is utilizing the TI HID Datapipe interface, I am new to Tiva (did play about with the launchpads when it was Stellaris) and I'm trying to find the best way to approach this. Previously I have used Vinculum UART to USB convertors, and they do produce UART to USB HID firmware however I would like to use the Tiva as I like the look of the series and want to move up from the MSPs I am using at the moment.

What would be the best place to start for this? Are there any existing examples which would be best to work from? Has anyone had any joy hosting MSPs with Tiva parts?

Many Thanks,

Nick

    I have this (almost) exact question today. How can I use a TM4C-series USB host to communicate with an MSP430-based USB client. Only my client is running the CDC stack.

    Nick? Did you get it figured out? Anybody else doing it? If not using TIVA, are you using another Cortex-based USB host to talk to an MSP430 client?

    Thanks!

    Hello Todd

    As of now there is no USB CDC Host driver on the TM4C and since the client device has a CDC Client Stack, you would need to make a new Host stack file for USB. To do so you would need to reuse one of the existing USB Host stack for the HID, Audio, etc as the template to start with.
