  1. Warm-up Lab Lab 0 – Warm-up Lab • Acquire a Texas Instruments MSP430 LaunchPad Development Tool. • Setup a CS user account. • Install (if necessary) and "run" blink.txt on the Digital State Machine Simulator. • Install (if necessary) and execute TI's Code Composer Studio (CCSv5.2). • Create a new assembly project. Load, assemble, and execute blinky.asm on your LaunchPaddevelopment tool. • Modify blinky.asm to double the toggle speed of the LED. • Use Code Composer to create a new C language project. Load, compile and execute blinky.c on your LaunchPaddevelopment tool as well. • Modify blinky.c to double the toggle speed of the LED. Lab 0 - Warm-up Lab

  2. Warm-up Lab Lab 0 – Warm-up Lab No lab source material should ever be emailed to another student! Please avoid even the appearance of cheating by looking on another's monitor. • Read again the Academic Honesty declaration. Students are encouraged work together in as far as discussing, clarifying, and helping each other understand material. Lab 0 - Warm-up Lab

  3. Warm-up Lab Lab 0 – Warm-up Lab • Acquire a Texas Instruments MSP430 LaunchPad Development Tool directly from Texas Instruments (or BYU Book Exchange, Amazon, Digikey,…). Lab 0 - Warm-up Lab

  4. Warm-up Lab Lab 0 – Warm-up Lab • Setup a CS user account. • If you are using your own computer, you can still set up your account. • If you are using a computer science department computer, then you should already have an account setup for you. (If you are setting up an account for the first time you may need to use your RouteY ID as your username and your student number as your password.) • Note: you may be required to change your password at this time. Lab 0 - Warm-up Lab

  5. Warm-up Lab Lab 0 – Warm-up Lab • Install (if necessary) and "run" blink.txt on the Digital State Machine Simulator. Toggles on and off Load Blinky.txt Lab 0 - Warm-up Lab

  6. Warm-up Lab Lab 0 – Warm-up Lab • Install (if necessary) and "clock" control.txt on the MSP430 micro-architecture simulator. Lab 0 - Warm-up Lab

  7. Warm-up Lab Lab 0 – Warm-up Lab • Install (if necessary) and execute TI's Code Composer Studio CCSv5.xx. Lab 0 - Warm-up Lab

  8. Warm-up Lab Lab 0 – Warm-up Lab • Create a new assembly-only project. Load, assemble, and execute blinky.asm on your LaunchPaddevelopment tool.
