Data Structures | |
| struct | uhi_msc_lun_t |
| Logical Unit Number (LUN) structure information. More... | |
Macros | |
Interface with USB Host Core (UHC) | |
Definition and functions required by UHC. | |
| #define | UHI_MSC |
| Global definition which contains standard UHI API for UHC. More... | |
Typedefs | |
| typedef void(* | uhi_msc_scsi_callback_t )(bool) |
| Callback type used by uhi_msc_scsi() functions. More... | |
Enumerations | |
| enum | lun_status_t { LUN_GOOD = 0, LUN_FAIL = 1, LUN_NOT_PRESENT = 2, LUN_BUSY = 3 } |
| Status of LUN. More... | |
Functions | |
Functions Required by UHC | |
| uhc_enum_status_t | uhi_msc_install (uhc_device_t *dev) |
| Install interface. More... | |
| void | uhi_msc_enable (uhc_device_t *dev) |
| Enable the interface. More... | |
| void | uhi_msc_uninstall (uhc_device_t *dev) |

UHI for Mass Storage Class | |
Common APIs used by high level application to use this USB host class. | |
| bool | uhi_msc_is_available (void) |
| Tests if the interface UHI Mass Storage is available. More... | |
| uint8_t | uhi_msc_get_lun (void) |
| Gives the number of LUN available. More... | |
| uhi_msc_lun_t * | uhi_msc_get_lun_desc (uint8_t lun) |
| Gives information about a LUN. More... | |
| bool | uhi_msc_scsi_test_unit_ready (uint8_t lun, uhi_msc_scsi_callback_t callback) |
| Checks and update the status of the LUN. More... | |
| bool | uhi_msc_scsi_read_10 (uint8_t lun, uint32_t addr, uint8_t *ram, uint8_t nb_sector, uhi_msc_scsi_callback_t callback) |
| Reads a LUN data section to RAM buffer. More... | |
| bool | uhi_msc_scsi_write_10 (uint8_t lun, uint32_t addr, const uint8_t *ram, uint8_t nb_sector, uhi_msc_scsi_callback_t callback) |
| Writes a RAM buffer in a LUN data section. More... | |
USB Host Mass Storage Interface for Control Access Module | |
Layer added on UHI MSC interface to allow the usage of control access module. The control access module provides a common access at all memories and it is used by the File Systems available in ASF. | |
| uint8_t | uhi_msc_mem_get_lun (void) |
| Gives the number of available LUN. More... | |
| Ctrl_status | uhi_msc_mem_test_unit_ready (uint8_t lun) |
| Checks and update the status of the LUN. More... | |
| Ctrl_status | uhi_msc_mem_read_capacity (uint8_t lun, uint32_t *u32_nb_sector) |
| Returns the capacity of the LUN. More... | |
| uint8_t | uhi_msc_mem_read_sector_size (uint8_t lun) |
| Returns the sector size of the LUN. More... | |
| bool | uhi_msc_mem_wr_protect (uint8_t lun) |
| Checks if the LUN is write protected. More... | |
| bool | uhi_msc_mem_removal (void) |
| Checks if the device is removed. More... | |
| Ctrl_status | uhi_msc_mem_read_10_ram (uint32_t addr, void *ram) |
| Reads 512 bytes from the current LUN. More... | |
| Ctrl_status | uhi_msc_mem_write_10_ram (uint32_t addr, const void *ram) |
| Writes 512 bytes to the current LUN. More... | |
