Getting started on Linux with Launchpad development<\/a><\/p>\n

Windows setup<\/strong>
Install CCS v6.0.1<\/a><\/p>\n

Run the add in and update installations.<\/p>\n

Install the Stellaris package:
SW-LM3S-LM4F: Legacy StellarisWare\u00ae for LM3S and LM4F MCUs \u2013 September 2012 Release (v9453)<\/a><\/p>\n

Follow instructions for creating a new project:
Creating new CCS v5 Project with Stellarisware<\/a><\/p>\n

Import projects driverlib-cm4f and usblib-cm4f.<\/p>\n

RTOS<\/strong><\/p>\n

Time for tasks with CCS<\/a><\/p>\n

Adjusting the clock rate to 80 MHz:
FreeRTOSConfig.h
configCPU_CLOCK_HZ –set to 80000000
in main()
ROM_SysCtlClockSet –change SYSCTL_SYSDIV_4 to SYSCTL_SYSDIV_2_5<\/p>\n

Adjusting the Tick period:
FreeRTOSConfig.h
configTICK_RATE_HZ to 10000
StellarisWare\/third_party\/FreeRTOS\/Source\/portable\/CCS\/ARM_CM4F\/portmacro.h
#define portTICK_RATE_MS ( ( portTickType ) 10000 \/configTICK_RATE_HZ )
–These two values must match!<\/p>\n

Examples from Embedded Systems: Introduction to ARM Cortex M Microcontrollers Fifth Edition <\/a>
Working with TI’s CCS<\/strong>
Profiling<\/a><\/p>\n

PL2303hx USB to TTL (UART adapter)<\/strong><\/p>\n

USB Serial Adapter on Mac OS X<\/a>
Adafruit link<\/a>
Sparkfun serial adapter page<\/a>
CoolTerm, a serial terminal<\/a><\/p>\n

On OS X <\/strong><\/p>\n

ls \/dev\/tty.*<\/p>\n

should see \/dev\/tty.usbserial<\/p>\n

screen \/dev\/tty.usbserial 115200
cntr-a, cntr-k to quit<\/p>\n

LM4F120H5QR replaced byTM4C1233H6PM, then support dropped.<\/p>\n
