### Handle Parameter Initialization

Source: https://github.com/stmicroelectronics/lis2mdl-pid/blob/master/README.md

If required by your platform read and write functions, initialize the handle parameter within the device context.

```c
dev_ctx.handle = &platform_handle;
```

--------------------------------

### Device Context Initialization

Source: https://github.com/stmicroelectronics/lis2mdl-pid/blob/master/README.md

Declare and initialize the device context structure with the platform-specific read, write, and delay functions.

```c
xxxxxxx_ctx_t dev_ctx; /** xxxxxxx is the used part number **/
dev_ctx.write_reg = platform_write;
dev_ctx.read_reg = platform_read;
dev_ctx.mdelay = platform_delay;
```

--------------------------------

### Optional Platform Delay Function

Source: https://github.com/stmicroelectronics/lis2mdl-pid/blob/master/README.md

Optionally define this C function if the driver requires a delay with millisecond granularity.

```c
void platform_delay(uint32_t millisec)
```

--------------------------------

### Platform Read/Write Functions

Source: https://github.com/stmicroelectronics/lis2mdl-pid/blob/master/README.md

Define these C functions to handle sensor hardware bus transactions (SPI or I²C). The write function must return 0 for success.

```c
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)
```

--------------------------------
