Part Number: TM4C1294NCPDT

Hi,

1.we are using the hardware EK-TM4C194XL launch pad and IDE is CCS 6.1,

2. We are trying to flash usb_dev_cserial example project from tiva ware library. but it's not working in our launchpad board.

3. What is the issue for that. We need to create one Virtual Seril COM port. Is there any example code available for my application?.

Hello Chidambaram,

Are you using Windows 10?

Hello Ralph Jacobi,

We flashed the code in launchpad.
But ,in the PC we didn't see any serial Port in device manager window. What is the issue for that?.

Hello Chidambaram,

The USB Composite example for TivaWare is not working properly with Windows 10 and is an open bug we are working to resolve.

However the good news is that since you indicated you just need one virtual Serial COM Port, I can provide an example that will work for you!

This TivaWare-based project will enumerate a single CDC COM port on Windows 10: 3678.usb_dev_cdcserial.zip
