Introduction

This repository contains platform-independent drivers and examples for STMicroelectronics MEMS sensors. The sensors drivers and examples are listed by product. Every product folder contains:

'driver' folder

This folder contains the driver files of Mems Sensor (.h and .c) to be included in your project. Driver documentation can be generated using Doxigen tool.

'examples' folder:

This folder contains examples showing how to integrate the Standard C driver in a project. They are written for STM32 Microcontroller using CubeMX API, but they can be used as a guideline for every platform.

Integration details

The driver is platform-independent, you only need to define the two functions for writing to and reading from Mems hardware bus (SPI or I2C).

Source code integration

• Include in your project the driver files of Mems Sensor (.h and .c) located in the 'driver' folder of the desider product
• Define in your code the read and write functions that use the I2C or SPI platform driver like the following:

    int32_t platform_write(void *handle, uint8_t Reg, uint8_t *Bufp, uint16_t len)
    int32_t platform_read(void *handle, uint8_t Reg, uint8_t *Bufp, uint16_t len)

• Initialize the structure of device interface:

      dev_ctx.write_reg = platform_write;
      dev_ctx.read_reg = platform_read;

• If needed by the platform read and write functions, initialize the handle parameter:

      dev_ctx.handle = &platform_handle;

Required properties

• A standard C compiler for the desired target
• A C library for the desired target and the desired interface (SPI, I2C)
