TM4C1294NCPDT: USB1.1 Support

Part Number: TM4C1294NCPDT

Hi, 

my customer replaced an old Stellaris design with TM4C1294NCPDT. The original Stellaris board was using USB1.1 and to minimize SW effort they want to use USB 1.1 with TM4C1294NCPDT.

Please advise how this can be done. 

Thanks

Josef

    Hello Josef,

    USB1.1 is also known as 'USB Full Speed' and that is the default USB speed we support with TM4C129x. The USB 2.0 support from TM4C129x is that the device can support 'USB High Speed' with an external USB PHY.

    See below image about USB speeds.

    So your customer does not need to do anything special to support USB 1.1, just use TivaWare and USB Library as is and they will be operating as they desire.
