# 1 - Introduction
|
||
|
|
||
|
Sensor driver for LSM6DSOX sensor written in C programming language. This repository contains the sensor driver files (.h and .c) to be included, or linked directly as a git submodule, in your project. The driver is MISRA compliant and the documentation can be generated using the [Doxygen](http://www.doxygen.org/) tool.

# 2 - Integration details
|
||
|
|
||
|
The driver is platform-independent, you only need to define two functions for read and write transactions from the sensor hardware bus (ie. SPI or I²C). **A few devices integrate an extra bit in the communication protocol in order to enable multi read/write access, this bit must be managed in the read and write functions defined by the user.** Please refer to the read and write implementation in the [reference examples](https://github.com/STMicroelectronics/STMems_Standard_C_drivers/tree/master/lsm6dsox_STdC/examples).

### 2.a Source code integration
|
||
|
|
||
|
- Include in your project the driver files of the sensor (.h and .c)
|
||
|
- Define in your code the read and write functions that use the I²C or SPI platform driver like the following:
|
||
|
|
||
|
```
|
||
|
/** Please note that is MANDATORY: return 0 -> no Error.**/
|
||
|
int32_t platform_write(void *handle, uint8_t Reg, const uint8_t *Bufp, uint16_t len)
|
||
|
int32_t platform_read(void *handle, uint8_t Reg, uint8_t *Bufp, uint16_t len)
|
||
|
```
|
||
|
|
||
|
- Declare and initialize the structure of the device interface:
|
||
|
|
||
|
```
|
||
|
xxxxxxx_ctx_t dev_ctx; /** xxxxxxx is the used part number **/
|
||
|
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;
|
||
|
```
|
||
|
|
||
|
Some integration examples can be found [here](https://github.com/STMicroelectronics/STMems_Standard_C_drivers/tree/master/lsm6dsox_STdC/examples).

### 2.b Required properties
|
||
|
|
||
|
> - A standard C language compiler for the target MCU
|
||
|
> - A C library for the target MCU and the desired interface (ie. SPI, I²C)
