I have run the program as an example, but the error message .

Hello Truong

Please make sure that the TivaWare path is included during compile and so is the driverlib.lib file for Keil

thank.i did it

Hello Truong

So now does it compile without any errors?

Regards
Amit

yes.thank you

Please let me know #include inc/tm4c123gh6pm.h definition ?

Hello Truong

I would suggest not using the include definition as it uses DRM method which should be avoided if you are used to API based coding method. It will create more issues in terms of code readability and maintenance as your project progresses. Not to mention debugging a failure due to incorrect bit usage will be more aggravating to debug for both you and us.
