Configuration¶

Functions¶

mira_config_get_size¶

mira_size_t mira_config_get_size(
    void);

Get size of non-volatile configuration memory.

Return

The available size.

mira_config_read¶

mira_status_t mira_config_read(
    void*         dst,
    mira_size_t   size);

Read from non-volatile configuration memory. This is useful to store per-unit configuration and identification parameters, such as product type or network parameters.

Parameters

Parameter	Description
`dst`	Pointer to where the read data should be stored.
`size`	Number of bytes to read.

Return

Status code indicating if the operation was successful.

Value	Description
`MIRA_SUCCESS`	The operation was successful.
`MIRA_ERROR_INVALID_VALUE`	Base + size is out of memory region.

mira_config_write¶

mira_status_t mira_config_write(
    void*         src,
    mira_size_t   size);

Write to non-volatile configuration memory. This is useful to store per-unit configuration and identification parameters, such as product type or network parameters. Writing will erase any previous data in the non-volatile configuration memory. Writing is non-blocking.

Parameters

Parameter	Description
`src`	Pointer to the data to be written. Data on this address must not be changed until configuration memory controller is no longer busy.
`size`	Number of bytes to write.

Return

Status code indicating if the operation was successful.

Value	Description
`MIRA_SUCCESS`	The operation started successfully.
`MIRA_ERROR_INVALID_VALUE`	Base + size is out of memory region.

mira_config_is_working¶

mira_bool_t mira_config_is_working(
    );

Check if the non-volatile configuration memory controller is busy. Used to wait for write completion as in the following example:

Return

Value	Description
`MIRA_TRUE`	Configuration memory controller is busy working.
`MIRA_FALSE`	Configuration memory controller is not busy working.
