The correct way to build the directory for uVision projects is
ValvanoWare    (you can choose any name for this directory)
   SimpleProject_1968asm (downloaded project from Valvano)
   YourLabProject  (solutions to your labs)

To build a directory for the LM4F120 or TM4C123
    driverlib (with driverlib-cm4f.lib in it)

This is an example assembly project with two source code files

How to install Keil uVision for the Arm, MDK-Lite (32KB) Edition. It does not require a serial number or license key. If you are developing code for a Texas Instruments microcontroller, I suggest you do NOT upgrade to Keil version 5. Rather I suggest you stay with version 4.73:
1) Go to
    Enter your contact information with valid address, phone and email (use your official UT email address),
    Company = University of Texas at Austin,
    Click submit
2) Right-click on MDK473_A.EXE (571,320K)  and save it to your computer
3) Install

Texas Instruments Stellarisware has lots of example files (it is free)
1) Go to
2) Click get software
3) Create an account at Texas Instruments (use your official UT email address)
4) Certify you are not going to export the software to other countries
5) company web site is
6) end application: I put other=”education” use “Educational lab experiments”
7) Download and install.
