Out of the Box Demo

The EK-TM4C1294XL comes pre-programmed with a quick-start demo application. The demo application is known as qs-iot (QuickStart Internet-of-Things). The source can be found in the examples\boards\ek-tm4c1294xl\qs-iot directory of the TivaWare installation you will download later. This example is cloud enabled with Exosite. Within minutes you will be monitoring and controlling your Connected LaunchPad from the cloud.

Create an account on

Proceed to and create a user account. You will need to provide a valid email address and password. You will be required to click a link in your email to activate the account.

Click the link the getting started section of the Exosite homepage to add a new device.

Once you login you will see the home screen of your Exosite account. On the left you will see a Getting Started Guide Widget with instructions on how to add devices. Click add new device.

Select EK-TM4C1294XL Connected LaunchPad from the device drop down

Select EK-TM4C1294XL Connected LaunchPad from the device drop down list. And then click the Continue button to go to the next page.

Insert the MAC address found on your device

Input the MAC address for your device. This can be found with LM Flash Programmer or by looking at the sticker on the bottom of the board.

NOTE: Do not lose this MAC address. Performing a Debug Mass Erase on the TM4C1294NCPDTI with LM Flash Programmer (or any other tool) will remove the MAC address from the device memory. Use LM Flash Programmer to re-program the USER0 and USER1 flash registers with this MAC if needed. A standard flash erase does not erase the MAC address. Only the special debug mass erase command will erase the EEPROM contents and MAC address. Debug mass erase restores a device to essentially the same condition in which it was shipped from the factory.

Power up the Connected LaunchPad and connect it to the Internet with included cables.

Plug the A (large flat) end of the provided USB cable into your computer. Plug the micro-B end of the USB cable into the debug port on the top of the EK-TM4C1294XL. Make sure the jumper JP1 is in the bottom ICDI position. Plug the retractable Ethernet cable into the EK-TM4C1294XL and your router or switch with DHCP and an internet connection.

The EK-TM4C1294XL Powers up and LED D4 should light solid on. This indicates an Ethernet connection is detected. LED D3 will blink occasionally to indicate Ethernet traffic.

The ICDI provides a virtual serial port communication mechanism to interact with the target processor. Use device manager to determine the COM port number associated with the Stellaris Virtual Serial Port. Connect a terminal emulator program to this port with 115200 8N1 settings. Press Enter to see the > command prompt. Type help for list of available commands and brief description of how to use them.
