FP-SNS-ALLMEMS1 Firmware Package

latest tag

The FP-SNS-ALLMEMS1 is an STM32 ODE function pack. Thanks to this package you can connect your IoT node to a smartphone using BLE, and by using a suitable Android or iOS application such as the ST BLE Sensor app, you can visualize real-time environmental sensor data, motion sensor data, digital microphone levels, and battery level. With this package you can record on SD card the enviromental sensor data, motion sensor data and digital microphone levels. The package also allows to perform advanced functionality such as voice communication over BLE, sound source localization and acoustic beam forming using inputs from multiple microphones, as well sensor data fusion and accelerometer-based real-time activity recognition, gesture recognition, motion Intensity recognition. Moreover provides real-time information about: the user current pose based on data from a device, the user working mode (sitting at the desk or standing desk position), the tilt angles of the user device, the repetition quantity of various fitness activities performed by a user, the vertical movement. This package, together with the suggested combination of STM32 and ST devices can be used, for example, to develop wearable applications, and, more in general smart things applications.

The software runs on the STM32 microcontroller and includes all the necessary drivers to recognize the devices on the STM32 Nucleo development board and expansion boards, as well as on the STEVAL-BCNKT01V1 and STEVAL-MKS1BOX1 evaluation boards

The expansion is built on STM32Cube software technology to ease portability across different STM32 microcontrollers.

Known Issues

  • Inconsistent wchar_t size compiler warning is generated from STM32 Audio Library middlewares when using the library in IAR v 9.x for BlueCoin (STEVAL-BCNKT01V1). It doesn’t affect library performances.
  • For NUCLEO-L476RG and SensorTile.box (STEVAL-MKSBOX1V1) a compiler warning “L6989W: Could not apply patch sdcomp-29491-629360 to instruction VPOP” is generated from µVision toolchain. Some members of the STM32L4 family have an eratta for the FMC (Flexible Memory Controller) where a read burst access of 9 words or more is not supported by FMC. To prevent burst accesses that are greater than 8 words, a special linker patch was developed to patch certain instructions that result in burst accesses of greaterthan 8 words. The patch can be applied in most cases with a few exceptions. One of these exceptions is when the instruction to be patched is inside an IT (If-Then) block and is not the last instruction in that block. In this case this warning will be generated. Since the FMC is only used for external memory, you can ignore this warning if you are only using internal memory.
