Chapter 4

SWRU326 – November 2012

Application Development

TI supports the CC3000 EM board when paired with the following TI MCU host platforms:

•

MSP-EXP430FR5739

•

MSP-EXP430F5529

•

MSP-EXP430F5438

•

MSP-EXP430FG4618

•

DK-LM3S9B96

•

EK-LM4F232

To find example applications for each of the listed host platforms, go to the TI wiki at:

http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_for_MCU#TI_Platforms

.

In addition to the TI MCU platforms, the CC3000 EM board can be used on other platforms with the same
RF connector interface. For a host driver porting guide to assist with porting to other platforms, go to

http://processors.wiki.ti.com/index.php/CC3000_Host_Driver_Porting_Guide
