2nd Launchpad freq analyzer project github code

Getting started on Linux with Launchpad development

Windows setup
Install CCS v6.0.1

Run the add in and update installations.

Install the Stellaris package:
SW-LM3S-LM4F: Legacy StellarisWare® for LM3S and LM4F MCUs – September 2012 Release (v9453)

Follow instructions for creating a new project:
Creating new CCS v5 Project with Stellarisware

Import projects driverlib-cm4f and usblib-cm4f.


Time for tasks with CCS

Adjusting the clock rate to 80 MHz:
configCPU_CLOCK_HZ –set to 80000000
in main()
ROM_SysCtlClockSet –change SYSCTL_SYSDIV_4 to SYSCTL_SYSDIV_2_5

Adjusting the Tick period:
configTICK_RATE_HZ to 10000
#define portTICK_RATE_MS ( ( portTickType ) 10000 /configTICK_RATE_HZ )
–These two values must match!
