3. Quick Start Guide for USB Host Mass-Storage Module (UHI MSC)
This is the quick start guide for the with step-by-stepUSB Host Mass-Storage Module (UHI MSC)
instructions on how to configure and use the modules in a selection of use cases.
The use cases highlights several code fragments. The code fragments in the steps for setup can be
copied into a custom initialization function, while the steps for usage can be copied into, e.g., the main
application function.
3.1. Basic Use Case
In this basic use case, the "USB Host MSC (Single Class support)" module is used.
The "USB Host MSC (Multiple Classes support)" module usage is described in .Advanced Use Cases
This example do a simple physical memory access, but a file system module can be added to decode the
USB memory file system, see FatFS examples.
3.1.1. Setup Steps
As a USB host, it follows common USB host setup steps. Refer to .USB Host Basic Setup
3.1.2. Usage Steps
3.1.2.1. Example Code
Content of conf_usb_host.h:
#define USB_HOST_UHI UHI_MSC
#define UHI_MSC_CHANGE(dev, b_plug) my_callback_msc_change(dev, b_plug)
extern bool bool my_callback_msc_change(uhc_device_t* dev, b_plug);
#include "uhi_msc_mem.h" // At the end of conf_usb_host.h file
Add to application C-file:
static bool false my_flag_autorize_msc_check = ;
bool bool my_callback_msc_change(uhc_device_t* dev, b_plug)
{
(b_plug) {if
my_flag_autorize_msc_check = ;true
} {else
my_flag_autorize_msc_check = ;false
}
}
void void my_task( )
{
(!my_flag_autorize_msc_check) {if
;return
}
my_flag_autorize_msc_check = ;false
// Check all new USB disks plugged
(uint8_t lun=0; lun < uhi_msc_mem_get_lun(); lun++) {for
// Wait the end of USB disk install
(CTRL_BUSY == uhi_msc_mem_test_unit_ready(lun));while
(CTRL_GOOD != uhi_msc_mem_test_unit_ready(lun)) {if
// Removal disk not present or fail
;continue

}
// Read capacity
uint32_t max_lba;
uhi_msc_mem_read_capacity(lun, &max_lba);
}
}
3.1.2.2. Workflow
1. Ensure that conf_usb_host.h is available and contains the following configuration, which is the USB
host MSC configuration:
#define USB_HOST_UHI UHI_MSC
Note:  It defines the list of UHI supported by USB host.
#define UHI_MSC_CHANGE(dev, b_plug) my_callback_msc_change(dev, b_plug)
extern bool my_callback_msc_change(uhc_device_t* dev, bool b_plug);
Note:  This callback is called when a USB device MSC is plugged or unplugged.
2. The access of the USB memories is allowed through functions described in .API Overview
3.2. Advanced Use Cases
For more advanced use of the UHI MSC module, see the following use cases:
•Enable USB High Speed Support
•Multiple Classes Support
•Dual Roles Support
3.3. Enable USB High Speed Support
In this use case, the USB host is used to support USB high speed.
3.3.1. Setup Steps
Prior to implement this use case, be sure to have already applied the UHI module "basic use case".
3.3.2. Usage Steps
3.3.2.1. Example Code
Content of conf_usb_host.h:
#define USB_HOST_HS_SUPPORT
3.3.2.2. Workflow
1. Ensure that conf_usb_host.h is available and contains the following parameters required for a USB
device high speed (480Mbit/s):
#define USB_HOST_HS_SUPPORT
3.4. Multiple Classes Support
In this use case, the USB host is used to support several USB classes.

3.4.1. Setup Steps
Prior to implement this use case, be sure to have already applied the UHI module "basic use case".
3.4.2. Usage Steps
3.4.2.1. Example Code
Content of conf_usb_host.h:
#define USB_HOST_UHI UHI_HID_MOUSE, UHI_MSC, UHI_CDC
3.4.2.2. Workflow
1. Ensure that conf_usb_host.h is available and contains the following parameters:
#define USB_HOST_UHI UHI_HID_MOUSE, UHI_MSC, UHI_CDC
Note:  USB_HOST_UHI defines the list of UHI supported by USB host. Here, you must add all
classes that you want to support.
3.5. Dual Roles Support
In this use case, the USB host and USB device are enabled, it is the dual role.
Note:  On the Atmel boards, the switch of USB role is managed automatically by the USB stack thank to
a USB On-The-Go (OTG) connector and its USB ID pin. Refer to section "Dual roles" for further
information in the application note:
•Atmel AVR4950: ASF - USB Host Stack
3.5.1. Setup Steps
Prior to implement this use case, be sure to have already applied the UHI module "basic use case".
3.5.2. Usage Steps
3.5.2.1. Example Code
Content of conf_usb_host.h:
#define UHC_MODE_CHANGE(b_host_mode) my_callback_mode_change(b_host_mode)
extern void my_callback_mode_change(bool b_host_mode);
Add to application C-file:
void void usb_init( )
{
//udc_start();
uhc_start();
}
bool my_host_mode;
void bool my_callback_mode_change( b_host_mode)
{
my_host_mode = b_host_mode;
}
void void my_usb_task( )
{
(my_host_mode) {if

14
// CALL USB Host task
} {else
// CALL USB Device task
}
}
3.5.2.2. Workflow
1. In case of USB dual roles (Device and Host), the USB stack must be enabled by uhc_start()
and the udc_start() must not be called.
//udc_start();
uhc_start();
2. In dual role, to know the current USB mode, the callback to notify the mode changes can be used.
•Ensure that conf_usb_host.h contains the following parameters:
#define UHC_MODE_CHANGE(b_host_mode)
my_callback_mode_change(b_host_mode)
extern void my_callback_mode_change(bool b_host_mode);
•Ensure that application contains the following code:
bool my_host_mode;
void bool my_callback_mode_change( b_host_mode)
{
my_host_mode = b_host_mode;
}
void void my_usb_task( )
{
(my_host_mode) {if
// CALL USB Host task
} {else
// CALL USB Device task
}
}
