Your request is vague. There are many considerations such as format of the data and sample rate that you need to consider. I have attached a simple project that uses the ADC and the UART. Use the Code Composer Studio "File" -> "Import" function to add this project to your code space.

Sir,

I am already use your sending link but i want to sample rate only 2048 per sec. So please tell where i will change in this code.

Actually sir, I want to send push button (sw1 or sw2) status ( press or not) in binary form on UART.

Look at the file: C:\ti\TivaWare_C_Series-2.1.4.178\examples\boards\ek-tm4c123gxl\drivers\buttons.c. This file has functions for configuring the push buttons on the EK-TM4C123GXL launchpad and for reading either the raw value or a de-bounced value. You can use the UARTCharPut() function to send the button state out of the UART.

See thread https://e2e.ti.com/support/tools/ccs/f/81/t/882066 for information about doing 2048 samples/second.
