usb interface in interrupt mode

earnest vekariya

I want to interface the microcontroller as a mouse.For example it should give the command of right click and left click on switch pressed.

What steps should be followed?

I'm sure this problem can be resolved quickly, but I'll just need to move the post to a different forum for you.

Lawrence Jeff published a few USB HID examples, including the usb mouse device as well for the EK-LM4F120XL board.

You can adopt it for TivaWare.

Earnest,

To add to Istvan's suggestions, there is also an airmouse example included in the TivaWare examples below is the path to them on my PC noting that your path may differ slightly dependent on which version of TivaWare you have installed and where you chose if you varied from the default location.

C:\ti\TivaWare_C_Series-2.1.1.71\examples\boards\ek-tm4c123gxl-boostxl-senshub\airmouse

If all you are interested in is the right and left clicks, you should be able to do this example be removing the sensor hub content and/or porting it to the chosen IO methodology on the launchpad.
