User Block Media Implementation (rm_block_media_user)

Middleware that implements a block media interface on the media of your choice. This module implements the Block Media Interface.

Overview

Features

This module is for using Block media with user-selected media.

Configuration

Block Media User has no output config settings.
The user is required to create the config settings etc. in the application.
The figure below is an example of the config definition when the user media in USB PMSC is RAM.

const rm_block_media_api_t g_rm_block_media_on_user_media =
{
    .open      = RM_BLOCK_MEDIA_RAM_Open,
    .mediaInit = RM_BLOCK_MEDIA_RAM_MediaInit,
    .read      = RM_BLOCK_MEDIA_RAM_Read,
    .write     = RM_BLOCK_MEDIA_RAM_Write,
    .erase     = RM_BLOCK_MEDIA_RAM_Erase,
    .infoGet   = RM_BLOCK_MEDIA_RAM_InfoGet,
    .statusGet = RM_BLOCK_MEDIA_RAM_StatusGet,
    .close     = RM_BLOCK_MEDIA_RAM_Close,
};

extern void r_usb_pmsc_block_media_event_callback(rm_block_media_callback_args_t * p_args);

const rm_block_media_cfg_t g_rm_block_media0_cfg =
{.p_extend = NULL, .p_callback = r_usb_pmsc_block_media_event_callback, .p_context = NULL, };

rm_block_media_instance_t g_rm_block_media0 =
{.p_api = &g_rm_block_media_on_user_media, .p_ctrl = NULL, .p_cfg = &g_rm_block_media0_cfg, };

Note

If you use block_media_user, you need to create a function that matches the media you are using.
In the above example, this is the function with RM_BLOCK_MEDIA_.
Register the created function in rm_block_media_api_t.
The registered rm_block_media_api_t is registered in p_api, which is a member of rm_block_media_instance_t.

Clock Configuration

This module has no required clock configurations.

Pin Configuration

This module does not use I/O pins.
