Status:
   version v2.3

Purpose:
   ST Microelectronics standard C platform-independent drivers for MEMS
   motion and environmental sensors.

Description:
   This package is an extract (examples have not been retained) of official
   C-Driver-MEMS package written by ST Microelectronics.
   It contains standard drivers for STMicroelectronics MEMS sensors to
   provide a common and stable interface to access sensor registers.
   For each supported sensor following files are provided:

       - xyz_reg.c: contains the function to read/write 'xyz' sensor registers
       - xyz_reg.h: contains structures and defines to describe in details
                    the 'xyz' sensor registers.

   The driver is platform-independent, you only need to define the two
   functions for read and write transactions from the sensor hardware bus
   (ie. SPI or I2C). In addition you may define a mdelay (milliseconds)
   routine.

   Define in your 'xyz' driver code the read and write functions that use the
   I2C or SPI platform driver (plus the optional mdelay function) like the following:

   /** Please note that is MANDATORY: return 0 -> no Error.**/
   int platform_wr(void *handle, u8_t reg, const u8_t *bufp, u16_t len);
   int platform_rd(void *handle, u8_t reg, u8_t *bufp, u16_t len);

   /** Component optional fields **/
   void platform_mdelay(u32_t millisec);


   stmdev_ctx_t stmdev_ctx = {
       .read_reg = (stmdev_read_ptr) platform_rd,
       .write_reg = (stmdev_write_ptr) platform_wr,

       /** Component optional fields **/
       .mdelay = (stmdev_mdelay_ptr) platform_mdelay,
   };
