Table of Contents

Introduction

The SimpleLink™ Wi-Fi® CC3220/3120 device family is a single-chip with built-in Wi-Fi connectivity, created for IoT (Internet of Things) purposes. The CC3220 device is a wireless MCU that integrates a high-performance ARM® Cortex®-M4 MCU, allowing customers to develop an entire application with a single IC.

The Texas Instruments royalty-free SimpleLink host driver provides a complete software library, made especially for developing Wi-Fi® applications for the CC3220/CC3120 network processors.

This is version 2_0_1_15 of the SimpleLink host driver.

Content and Documentation

The SimpleLink CC3X20 is comprised of two components:

The Core driver, which is a generic NWP driver for the CC3120\3220 SimpleLink products. The other is platform abstraction layer, which provides a means to communicate with the host platform hardware and operating system services.

The individual components have their own folders, refer to the table below.

Important notes

• This version of the Host driver supports BSD api for networking function calls, as well as leagcy
  simplelink api, with no need to recompile the driver.
  Furthermore, it also has an internal errno mechanism for the BSD networking calls.
  User can check errno after each call, to query which error occurred. To push the BSD support
  even further, three additional headers are included in the Host driver:
  • sys/errno.h
  • sys/socket.h
  • sys/netdb.h

  For users who wish to use their platform’s errno setter, rather than the driver’s
  a hook inside user.h is supplied, just set the define slcb_SetErrno to point to your
  errno setter function. also, undef the flag: SL_INC_INTERNAL_ERRNO.

• The compilation flag SL_INC_STD_BSD_API_NAMING is deprecated.
