More USB Examples in TivaWare for Launchpad (EK-TM4C123GXL)

Krithik Chandrashekar

Are there any additional USB Host examples for the Launchpad? I can't seem to find any outside of the bulk usb transfer example in the TivaWare folder, I've version 2.1.0.

Hello Krithik

You can retrofit the DK-TM4C123 examples for EK-TM4C123

Hello Amit,

Thanks for your prompt response. Which example should I look at if I want to read/write into a usb flash drive? Essentially, I would need host capability on the board.

Thanks,
Krithik

Hello Krithik,

That would be the following example...

C:\ti\TivaWare_C_Series-2.1.0.12573\examples\boards\dk-tm4c123g\usb_host_msc

Regards

Be advised for the 123 LaunchPad host mode generally requires the population of a couple of resistors. These connect PB0 and PB1 to ID and VBUS. The resistors are located near the USB OTG connector.

NOTE: this will put VBUS and ID on the BoosterPack connectors. You may now be applying 5V in unexpected ways to your BoosterPacks.

Understood, I did go through the note for the 5V VBUS on the User's Manual. Appreciate the heads up though.
