SN8000 WiFi Module with STM Discovery Board

250 replies posted 100 replies posted 50 replies posted

Here is an example of interfacing the BCM43362 based SN8000 WiFi module (from Murata) with STM32F4-Discovery board (with STM32F407 MCU).


The schematic below illustrates the connections required to connect the SN8000 to the STM32F4-Discovery board. Since the SN8000 comes as a module to connect to a PCB, a carrier board is needed to connect the module to the STM32F4-Discovery board.

If you have the SN8000 module mounted on a SDIO carrier board, which comes with the SN800 evaluation board, the following connection schema can be used to connect the module to the STM32F4-Discovery board.

For terminal interface between the STM32F4-Discovery board and host PC the following serial (RS232) connection is needed.


To connect a JTAG debugger (Olimex_ARM-USB-TINY-H) to the STM32F4-Discovery board follow the below connection.


For more information please take a look at this link: Interfacing STM32Fx-Discovery with WICED using JTAG Debugger


After setting up the hardware connections WICED SDK-3.x should be updated to run WICED applications on STM32F4-Discovery board with SN8000 WiFi module. Unzip the attached file with the following expected updates.


The STM32F407 directory goes to .../WICED/platform/MCU/STM32F4xx/GCC directory of the WICED SDK.



The STDiscovery407_BCM43362 platform files goes to .../platforms directory of the WICED SDK.

To build and run application using WICED SDK following Make Target could be used;

     <Application>-STDiscovery407_BCM43362 JTAG=Olimex_ARM-USB-TINY-H download run


To build and run a sample scan app use the following Make Target:

     snip.scan-STDiscovery407_BCM43362-debug JTAG=Olimex_ARM-USB-TINY-H download run
