Keil/Microvision - Creating a New Project for Tiva™ C Series TM4C123G LaunchPad

1. Create New Folder on Documents (or any location) and name it
2. On Microvision ==> Project ==> New Microvision Project & name it ==> ARM Cortex M4 ==> ARMCM4
3. Copy/paste "inc" folder that includes "tm4c123gh6pm.h" on new folder you created on step 1.
4. Copy/paste "startup.s on new folder your created on step 1.
5. On Microvision, right-click on Source Group 1
• Add existing ==> startup.s
• Add new item to group ==> c file ==> name it "main (or any that you'd like)"
6. Make sure to click on "options for target" ==> debug ==> "Use:" ==> "Stellaris ICDI"

Stepper Motor Code

/*
7 files needed for this code to work:
Header Files
1. stepper.h // don't add to source group
2. systick.h // don't add to source group

Source (group) Code Files (you only add .c type files, not .h which is called on the #include)
3. startup.s // add to source group
4. stepper.c // add to source group
5. main.c (in this case, mainStep.c) // add to source group
6. SysTick.c // add to source group
