Demo Bring up

Hardware Setup

1.1. Mount the adapter board on the back of the STM32F4-Discovery. Match J1 connectors with P1 connectors, and

J2 connectors with P2 connectors.

2. Mount the CC3100 Boosterpack on top of the adapter board. Be careful of orientation. Use the triangles on P1.1

of both boards to help you.

4. Connect the USB cables from the PC to both boards. Mini-USB for STM32F4-Discovery and micro-USB

for CC31XXEMUBOOST.

Application Bring up

1.1. Download the CC3100_STM32F4_Add_On package and extract the package at your CC3100 SDK location.

Replace all existing files in the SDK if conflict occurs.

2. Download STM32F4 Cube and copy "<stm32 cube>/Drivers" folder at

"<cc3100-sdk>/platform/stm32discovery"

3.3. Connect Mini-USB cable from STM32F4-Discovery board to the computer.

4. Connect Micro-USB cable from J6 on CC31XXEMUBOOST to computer and configure the terminal-program

for seeing the logs - CC31xx & CC32xx Terminal Setting has detailed instructions for configuring the

terminal-program.

5. Open getting_started_with_wlan_station or getting_started_with_wlan_ap project provided at

"<cc3100-sdk>/platform/stm32discovery/example_project_iar" using IAR.

6. Open sl_common.h and change SSID_NAME, SEC_TYPE and PASSKEY as per your access-point properties -

SimpleLink device will connect to this AP when the application is executed.

7.7. Build and run the application.

8.8. Follow the links to see application details:
