enum | USB_Device_ErrorCodes_t { DEVICE_ERROR_GetDescriptorNotHooked = 0 } |
#define USB_Device_IsRemoteWakeupSent | ( | ) | ((UDCON & (1 << RMWKUP)) ? false : true) |
Indicates if a Remote Wakeup request is being sent to the host. This returns true if a remote wakeup is currently being sent, false otherwise.
This can be used in conjunction with the USB_Device_IsUSBSuspended() macro to determine if a sent RMWAKEUP request was accepted or rejected by the host.
#define USB_Device_IsUSBSuspended | ( | ) | ((UDINT & (1 << SUSPI)) ? true : false) |
Indicates if the device is currently suspended by the host. While suspended, the device is to enter a low power state until resumed by the host. While suspended no USB traffic to or from the device can ocurr (except for Remote Wakeup requests).
This macro returns true if the USB communications have been suspended by the host, false otherwise.
#define USB_DEVICE_OPT_FULLSPEED (0 << 0) |
Mask for the Options parameter of the USB_Init() function. This indicates that the USB interface should be initialized in full speed (12Mb/s) mode.
#define USB_DEVICE_OPT_LOWSPEED (1 << 0) |
Mask for the Options parameter of the USB_Init() function. This indicates that the USB interface should be initialized in low speed (1.5Mb/s) mode.
Restrictions apply on the number, size and type of endpoints which can be used when running in low speed mode -- refer to the USB 2.0 standard.
#define USB_Device_SendRemoteWakeup | ( | ) | MACROS{ UDCON |= (1 << RMWKUP); }MACROE |
Sends a Remote Wakeup request to the host. This signals to the host that the device should be taken out of suspended mode, and communications should resume.
Typically, this is implemented so that HID devices (mice, keyboards, etc.) can wake up the host computer when the host has suspended all USB devices to enter a low power state.
Enum for the ErrorCode parameter of the USB_DeviceError event.
DEVICE_ERROR_GetDescriptorNotHooked |
Indicates that the GetDescriptor() method has not been hooked by the user application.
