LAUNCHXL2 RM46: CC3100 Wi-Fi Demo

This demo is designed to let you add Wi-FI connectivity to the Hercules MCU LaunchPad using the Simplelink CC3100 Wi-Fi boosterpack. The demo provides an example code that users can program on the Hercules RM46 LaunchPad and CC3100 boosterpack. It includes options for two operating modes : 1) Access Point Mode: CC3100 generates a pre-defined SSID that other Wi-Fi devices can connect with. 2) Station Mode: CC3100 is configured to connect to a (pre-defined) SSID.

At this time, the steps below are needed to add support for the RM46 Launchpad to the cc3100 SDK.
In the future the RM46 will be included in the CC3100 SDK.

Introduction

This demo requires tools to program the flash contents on the RM46 Launchpad and the CC3100 boosterpack, such as Uniflash and Code Composer Studio.
Uniflash 3.3 and up support both devices, Code Composer Studio (CCS) supports only the RM46 Launchpad.

• Download and install Uniflash 3.3 and up, _{required to move web content to CC3100 boosterpack.}
• Download and install Code Composer Studio, _{only required to rebuild the CCS project.}
• Download and install CC3100 SDK
  

  Note your installation folder (default is c:\ti\CC3100SDK_x.y.z\cc3100-sdk), we will call this '<install_dir>' in the following steps.

Install CC3100 SDK RM46 Patch

1. Download CC3100 SDK RM46 Support Patch, _{requires CC3100 SDK}
2. Extract the .zip to '<install_dir>\platform\', this will create the rm46-launchpad folder.
   This includes the HalCoGen project, the CC3100 SDK Wi-Fi demo source, and .out files _{(so building the project is not required)}.

Programming the CC3100 Boosterpack

1. Connect the CC3100 Boosterpack to the CC3100 Booster EMU board.
2. Plug in your Booster EMU board's USB cable to the SPI/GPIO/UART/NWP port.



3. Load your web content onto the boosterpack sFlash.
   Use the uniFlash configuration at this location <install_dir>\platform\rm46-launchpad\example_project_ccs\http_server_WIFI_demo_station\uniflash_template\http_server_WIFI_demo.usf.
   Visit the CC31xx UniFlash Quick Start Guide wiki for step-by-step instructions.
4. If you are missing web content files, the Launchpad will report them on the serial console.

Programming the RM46 Launchpad

1. Connect the CC3100 Boosterpack to the Launchpad Boosterpack site #1.
2. Plug in your LaunchPad's USB cable.
3. Load your project onto the Launchpad and test it out!
   Select the Access Point (AP) version if you want to connect to it using SSID '"<ap_mode_ssid>" or
   Select the Station version if you want it to connect to the default SSID "<ap_name>" with no security _{(such as a smart phone with tethering)}.
4. Use the uniFlash and the .out file at <install_dir>\platform\rm46-launchpad\example_project_ccs\http_server_WIFI_demo_station\RM\http_server_WIFI_demo_ap.out or http_server_WIFI_demo_station.out.
   

Running the RM46 Launchpad Wi-Fi Demo

This demo is based on the HTTP Server Sample Application with documentation available at <install_dir>\docs\examples\http_server.pdf.

• Optionally connect to the console with a terminal program to see debug information and the client IP address.

  Connect the provided micro USB cable to the XDS110 port on the RM46 Launchpad.

  Configure the terminal for a baudrate: 115200, Data bits: 8, Stop bits; 1, Parity: None, Flow Control: None, Putty Terminal Setup Example.

• If in AP mode connect a client to the CC3100 using its SSID name
  

  The default SSID "<ap_mode_ssid>".

• If in Station mode it will connect the specified SSID
  

  The default SSID "<ap_name>".

1. Open a web browser on the client and enter the IP of CC3100 in the client's address bar.

  Alternatively, 'mysimplelink.net' can also be entered for accessing the web page

2. Click the RM46 demo button to load the RM46 specific pages we loaded earlier.
3. Click on the I/O control demo tab to load the RM46 Launchpad I/O Control Demo page shown below.
• LED Control: On - will turn USER LEDB (GIOB_2) on solid
• LED Toggle: On - will toggle USER LEDB (GIOB_2) at the speed shown in Toggling Speed
• Button Counts: will get and clear the number of time USER SWITCHES A and B are pressed.
• Analog Input will update based on the state of the Q1 light sensor.
