Getting Started with the Stellaris EK-LM4F120XL LaunchPad Workshop
From Texas Instruments Embedded Processors Wiki
This workshop has been upgraded to the new Tiva TM4C123G LaunchPad Workshop located here. No further changes will be made to this page as of 14May2013.
Version 1.10 March 2013 Labs are based on CCS 5.3
The Getting Started with the Stellaris EK-LM4F120XL LaunchPad Workshop is a free, in-depth, hands-on introduction into Stellaris LM4F basics including:
- Introduction to the ARM® Cortex™-M4F and Peripherals
- Introduction to Code Composer Studio
- StellarisWare, Initialization and GPIO
- Interrupts and the Timers
- The Hibernation Module
- The Floating-Point Unit
- BoosterPacks and the Graphics Library
- Synchronous Serial Interface (no video yet)
- UART (no video yet)
- uDMA (no video yet)
Each of these sections includes an in-depth lab that will step you through the usage, programming and testing of the peripheral(s) or tool(s) covered.
The workshop is based on the low cost, expandable Stellaris LaunchPad Evaluation Kit. The LaunchPad board features an 80MHz LM4F120H5QR microcontroller, on-board emulation and BoosterPack XL format expansion pins. The LM4F120H5QR microcontroller has 256KB of flash memory, 32KB of RAM, 2KB of EEPROM, two 12-bit analog to digital converters, a USB 2.0 device port, a hibernation module, other serial connectivity and flexible GPIO.
Stellaris devices are supported by several Integrated Development Environments: Mentor Graphics® Mentor Embedded IDE, IAR Systems Embedded Workbench, ARM®’s Keil™ microVision IDE and Texas Instrument®’s Eclipse-based Code Composer Studio™. The workshop labs are based on Code Composer Studio, which is free and fully functional when connected to the LaunchPad board.
The workshop labs are constructed using StellarisWare™. StellarisWare is an extensive suite of license and royalty-free software designed to simplify and speed development of Stellaris-based microcontroller applications. StellarisWare includes the Peripheral Driver Library and the Graphics Library. The Peripheral Driver library is a set of functions for controlling the peripherals found on the Stellaris family of ARM Cortex-M microcontrollers. All LM4F devices provide this code in on-board ROM. The Stellaris Graphics Library is a set of graphics primitives and widgets for creating graphical user interfaces on Stellaris microcontroller-based boards that have a graphical display.
Expandability of the LaunchPad board is accomplished through its BoosterPack XL connectors. These connectors are backwards compatible with the original BoosterPack connectors. There are many BoosterPacks available through TI and third parties. In order to highlight the expansion capabilities of the Stellaris LaunchPad board and the use of the graphics library, the workshop includes the Kentec Display 3.5” LCD TouchScreen BoosterPack. You can purchase the BoosterPack directly from the manufacturer or through Newark Electronics.
Newly added to the workshop is Chapter 11: Synchronous Serial Interface. In order to run the lab you will need to purchase and modify an Olimex 8x8 LED BoosterPack . These boards are available through Mouser Electronics . Complete instructions on the needed modifications are in the chapter 11 lab. .
Attend a Live Workshop
You can attend a live version of this workshop taught by an experienced Texas Instruments instructor. Sign up here.
To run the labs, you will need the following:
- A 32 or 64-bit Windows XP, Windows 7 or Windows 8 laptop with 2G or more of free hard drive space. 1G of RAM should be considered a minimum … more is better.
- A laptop with Wi-Fi is highly desirable
- If you are working the labs from home, a second monitor will make the process much easier. If you are attending a live workshop, you are welcome to bring one.
- If you are attending a live workshop, please bring a set of earphones or ear-buds.
- If you are attending a live workshop, you will receive an evaluation board; otherwise you need to purchase one.
- If you are attending a live workshop, a digital multi-meter will be provided; otherwise you need to purchase one like the inexpensive version here 
- If you are attending a live workshop, you will receive a second A-male to micro-B-male USB cable. Otherwise, you will need to provide your own to complete Lab 7.
- If you are attending a live workshop, you will receive a Kentec 3.5” TFT LCD Touch Screen BoosterPack (Part# EB-LM4F120-L35). Otherwise, you will need to provide your own to complete Lab 10. You can purchase the BoosterPack directly from the manufacturer or through Newark Electronics.
- If you are attending a live workshop, Olimex 8x8 LED BoosterPacks will be available with both modifications. If you want to run this lab from home you will need to obtain and modify the board as detailed in the chapter 11 lab.
To run the labs, you will need the following:
- Code Composer Studio 5.3 or later
- The LM Flash Programmer
- The latest ICDI drivers
- The lab installation file
- The workshop workbook
- A terminal program like HyperTerminal (WinXP) or PuTTY
- The Windows side USB examples
- GIMP image manipulation tool
- The workbook pdf file
- The labs installation file
- The zipped PowerPoint presentation
- The Word doc files used to create the workbook
- The installation guide for workshop attendees
