| #define CLASS_SUBCLASS_PROTOCOL |
CLASS/SUBCLASS/PROTOCOL supported table list.
This table contains the CLASS/SUBCLASS/PROTOCOL that are supported by the reduced-host application. This table definition allows to extend the reduced application device support to an entire CLASS/ SUBCLASS/PROTOCOL instead of a simple VID/PID table list.
CLASS_SUBCLASS_PROTOCOL format definition:
#define CLASS_SUBCLASS_PROTOCOL {CLASS1, SUB_CLASS1, PROTOCOL1,
...
CLASSn, SUB_CLASSn, PROTOCOLn}
| #define DEVICE_ADDRESS 0x05 |
The address that will be assigned to the connected device.
Referenced by usb_host_task().
| #define HOST_AUTO_CFG_ENDPOINT ENABLE |
Try to configure the host pipe according to the device descriptors received.
| #define HOST_CONTINUOUS_SOF_INTERRUPT DISABLE |
Host Start-of-Frame interrupt always enabled.
| #define HOST_ERROR_RESTART ENABLE |
When host error state detected, go to detached state.
| #define HOST_STRICT_VID_PID_TABLE DISABLE |
The host controller will be limited to the strict VID/PID list.
When enabled, if the device VID/PID does not belong to the supported list, the host controller software will not go to deeper configuration, but to error state.
| #define ID_PIN_CHANGE_GENERATE_RESET ENABLE |
Force CPU reset upon ID pin change.
| #define MAX_EP_PER_INTERFACE 3 |
The maximal number of endpoints per interface supported.
Referenced by host_check_class().
| #define MAX_INTERFACE_SUPPORTED 0x03 |
The maximal number of interfaces that can be supported (composite device)
Referenced by host_check_class().
| #define NAK_RECEIVE_TIMEOUT 0x0FFF |
Number of NAK handshakes before time-out for receive functions (up to 0xFFFF)
Referenced by host_get_data().
| #define NAK_SEND_TIMEOUT 0x0FFF |
Number of NAK handshakes before time-out for transmit functions (up to 0xFFFF)
Referenced by host_send_data().
| #define NAK_TIMEOUT_ENABLE DISABLE |
Enable cpt NAK time-out for host transfer.
| #define SIZEOF_DATA_STAGE 250 |
The size of RAM buffer reserved for descriptor handling.
Referenced by host_check_class().
| #define TIMEOUT_DELAY 10 |
Delay 1/4 s (250 ms) before time-out value.
Referenced by host_get_data(), host_send_data(), and usb_general_interrupt().
| #define TIMEOUT_DELAY_ENABLE ENABLE |
Enable time-out delay for host transfer.
| #define USB_HOST_PIPE_INTERRUPT_TRANSFER DISABLE |
USB host pipes transfers use USB communication interrupt (allows to use non-blocking functions)
| #define VID_PID_TABLE {ATMEL_VID, 1, MS_EXAMPLE_PID} |
VID/PID supported table list.
This table contains the VID/PID that are supported by the reduced-host application.
VID_PID_TABLE format definition:
#define VID_PID_TABLE {VID1, number_of_PIDs_for_VID1, PID11_value, ..., PID1X_Value,
...
VIDn, number_of_PIDs_for_VIDn, PIDn1_value, ..., PIDnY_Value}
| void host_sof_action | ( | void | ) |
host_sof_action
This function increments the sof_cnt counter each time the USB Start-of-Frame interrupt subroutine is executed (1 ms). Useful to manage time delays
| void host_suspend_action | ( | void | ) |
