FP-SNS-ALLMEMS1 introduced by the development board package

Operation steps :

1 Because BlueCoin default built-in firmware FP-AUD-SMARTMIC1, if you want to use FP-SNS-ALLMEMS1 package, we need to update the firmware using the ST-Link. However, BlueCoin does not have ST-Link and requires the STM32-Nucleo board.

Note : At the CN2 mark on the Nucleo board , both black jumper caps must be removed.

2 Connect the BlueCoin kit to the Nucleo board via a 5pin flat cable , pay attention to align the Pin 1 of the SWD interface . Then, respectively, and Mini-USB Micro-USB cable to connect the board and BlueCoin Nucleo plate.

3 Open the Projects\Multi\Applications\ALLMEMS1\EWARM\STM32F446RE-BlueCoin\ALLMEMS1_BC.eww project in the FP-SNS-ALLMEMS1 software package with IAR , and compile the firmware bin/hex . It also supports SystemWorkbench and uVisiontoolchain to compile the corresponding project.

Note : IAR8.11.1 will encounter problems with compilation. The lib that comes with it may be compiled in a lower version, not compatible, and will be optimized later. In this case, you can copy Projects\Multi\Applications\ALLMEMS1\Binary\STM32F446RE-BlueCoin\ALLMEMS1_BC.bin to the Projects\Multi\Applications\ALLMEMS1\EWARM\STM32F446RE-BlueCoin\STM32F446RE-BlueCoin\Exe\ directory.

4 Run the Projects\Multi\Applications\ALLMEMS1\EWARM\STM32F446RE-BlueCoin\CleanALLMEMS1_IAR_BC.bat script to automatically program the firmware.

5 After successful programming, unplug the Nucleo board and restart the BlueCoin board. After the normal boot, the LEDs in the up, down, left, and right directions will flash when there is no phone connection .

6 Mobile phone download and install BlueMS (there is an article in front of it), then open the Bluetooth, click " Start Scan " , select the scanned Bluetooth device, click the connection to operate the relevant functions.
