#define USB_Host_ClearRemoteWakeupSent | ( | ) | MACROS{ UHINT &= ~(1 << RXRSMI); }MACROE |
Clears the flag indicating that a Remote Wakeup request has been issued by an attached device.
#define USB_HOST_DEVICEADDRESS 1 |
Indicates the fixed USB device address which any attached device is enumerated to when in host mode. As only one USB device may be attached to the AVR in host mode at any one time and that the address used is not important (other than the fact that it is non-zero), a fixed value is specified by the library.
#define USB_Host_IsBusSuspended | ( | ) | ((UHCON & (1 << SOFEN)) ? false : true) |
Returns true if the USB bus has been suspended via the use of the USB_Host_SuspendBus() macro, false otherwise. While suspended, no USB communications can occur until the bus is resumed, except for the Remote Wakeup event from the device if supported.
#define USB_Host_IsDeviceFullSpeed | ( | ) | ((USBSTA & (1 << SPEED)) ? true : false) |
Returns true if the attached device is currently enumerated in Full Speed mode (12Mb/s), or false if the attached device is enumerated in Low Speed mode (1.5Mb/s).
#define USB_Host_IsRemoteWakeupSent | ( | ) | ((UHINT & (1 << RXRSMI)) ? true : false) |
Returns true if the attached device is currently issuing a Remote Wakeup request, requesting that the host resume the USB bus and wake up the device, false otherwise.
#define USB_Host_IsResetBusDone | ( | ) | ((UHCON & (1 << RESET)) ? false : true) |
Determines if a previously issued bus reset (via the USB_Host_ResetBus() macro) has completed. This macro returns true if no bus reset is currently being sent, false otherwise.
#define USB_Host_IsResumeFromWakeupRequestSent | ( | ) | ((UHCON & (1 << RESUME)) ? false : true) |
Returns true if no resume from Remote Wakeup request is currently being sent to an attached device, false otherwise.
#define USB_Host_ResetBus | ( | ) | MACROS{ UHCON |= (1 << RESET); }MACROE |
Resets the USB bus, including the endpoints in any attached device and pipes on the AVR host. USB bus resets leave the default control pipe configured (if already configured).
If the USB bus has been suspended prior to issuing a bus reset, the attached device will be woken up automatically and the bus resumed after the reset has been correctly issued.
#define USB_Host_ResumeBus | ( | ) | MACROS{ UHCON |= (1 << SOFEN); }MACROE |
Resumes USB communications with an attached and enumerated device, by resuming the transmission of the 1MS Start Of Frame messages to the device. When resumed, USB communications between the host and attached device may occur.
#define USB_Host_ResumeFromWakeupRequest | ( | ) | MACROS{ UHCON |= (1 << RESUME); }MACROE |
Accepts a Remote Wakeup request from an attached device. This must be issued in response to a device's Remote Wakeup request within 2ms for the request to be accepted and the bus to be resumed.
#define USB_Host_SuspendBus | ( | ) | MACROS{ UHCON &= ~(1 << SOFEN); }MACROE |
Suspends the USB bus, preventing any communications from occuring between the host and attached device until the bus has been resumed. This stops the transmission of the 1MS Start Of Frame messages to the device.
#define USB_HOST_TIMEOUT_MS 1000 |
Constant for the maximum software timeout period of sent USB transactions to an attached device. If a device fails to respond to a sent control request within this period, the library will return a timeout error code.
This value may be overridden in the user project makefile as the value of the USB_HOST_TIMEOUT_MS token, and passed to the compiler using the -D switch.
Enum for the error codes for the USB_DeviceEnumerationFailed event.
Enum for the error codes for the USB_HostError event.
enum USB_Host_States_t |
Enum for the various states of the USB Host state machine. Only some states are implemented in the MyUSB library - other states are left to the user to implement.
For information on each state, refer to the USB 2.0 specification.
