Dean Camera cf2776531c Add extra check for OUT ZLP in the CDC Device Class driver service task to quickly clear zero-length termination packets from the host. 2009-08-31 12:43:28 +00:00
Dean Camera 6d1adf7339 Updated Benito project -- added hardware interrupt and software buffering for serial data reception to prevent missed characters, condensed pulse generation counters into a struct for clarity. 
Added check to CDC_Device_BytesReceived() to ensure 0 is returned when device is not enumerated to a host.

Move AVRISP project's V2Protocol_DelayMS() function to be static inline, as it is now very minimal. Added extra project doxygen documentation.
 2009-08-25 08:09:49 +00:00
Dean Camera 09bedd6555 Added return values to the CDC and MIDI class driver transmit functions. 2009-08-16 14:30:46 +00:00
Dean Camera df5500e81c Added CDC_Device_Flush() command to the CDC Device mode class driver. 
Minor updates to the unfinished SideShow demo for clarity.

Added unfinished MassStorageHost class driver demo.
 2009-08-13 06:43:17 +00:00
Dean Camera f4814771d2 Completion of initial CDC host mode class driver. 
Adjustments to the CDC and MIDI device class drivers to use sizeof() on the actual variable being transmitted or received rather than its datatype to reduce possible mistakes.
 2009-08-11 02:09:11 +00:00
Dean Camera 8711dc7ced Fix issue in CDC device class driver where received data the size of the data endpoint could lock up the driver. 
Further work on the new CDC and HID host mode class drivers.

Reset changelog et. al. to reset development information for the new version currently under development.
 2009-08-11 01:52:15 +00:00
Dean Camera a9d5e129b7 Changed over manual loops waiting for endpoints to be ready to use the library Endpoint_WaitUntilReady() function for robustness. Fixes issues with terminated transfers on the host locking up USB devices. 2009-08-05 09:37:45 +00:00
Dean Camera c5038f1bf4 Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only. 
Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.

Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.
 2009-08-05 06:36:31 +00:00
Dean Camera eff07bb877 Fix issue with CDC device demos causing broken communications when the device tries to send data before the host has set the line encoding. 2009-08-04 08:06:26 +00:00
Dean Camera 864196c884 State information for class drivers is now zeroed out during enumeration (both in device and host mode) to ensure sane values after each enumeration. User code should no longer explicitly set state information as this is no longer preserved. 2009-07-27 23:19:17 +00:00
Dean Camera e071f3897a Added new USB_DeviceState variable to keep track of the current Device mode USB state. 
Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.

Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.

Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.

Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.
 2009-07-21 13:31:21 +00:00
Dean Camera 67f390fe74 Add explicit guards to all device mode tasks to ensure the device is connected and configured before running the task, to prevent any user tasks from locking up the main USB task if the device has not been properly configured. 2009-07-21 02:48:41 +00:00
Dean Camera f1076ac4d6 Added const modifiers to device mode class drivers. 
Added parameter directions to function parameter documentation.

Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).
 2009-06-28 13:39:08 +00:00
Dean Camera 00d0883507 Added USE_INTERNAL_SERIAL compile time option to automatically read out the internal unique serial number as the device's serial number descriptor on supported AVR models. 2009-06-20 11:43:26 +00:00
Dean Camera f896c00c48 Break device mode class driver interfaces into seperate config and state structs which are then combined, for clarity. Move device mode class driver interfaces back into the device mode class driver headers from the common class headers to make room for host class interfaces. 2009-06-18 10:31:55 +00:00
Dean Camera afe6ae1402 Add host mode USB Class driver stubs, add beginnings of a CDC host class driver. 
Split out common defines/types from class drivers into a seperate common class driver directory.

Make central USB Class driver dispatch headers, used for both device and host modes.
 2009-06-14 15:55:13 +00:00
Dean Camera 9798440ca4 Changed to new device mode Class Driver function name prefixes to make way for similar host mode Class drivers. 2009-06-11 06:15:45 +00:00
Dean Camera bde64666fb Finished CDC device class driver documentation. 2009-06-08 10:06:49 +00:00
Dean Camera 3d1baa6f95 Added multiple Report ID support to the HID class driver. Removed OUT endpoint support from HID driver (all OUT reports are now processed through control requests) as a seperate endpoint had issues with determining the exact output report length. 2009-06-05 02:23:31 +00:00
Dean Camera 7665bf323e Fixed EVENT_USB_CDC_ControLineStateChanged() event not taking the CDC interface structure as a parameter. 
Converted TestApp demo over to the new demo structure.

More class driver documentation improvements.
 2009-06-04 06:26:35 +00:00
Dean Camera 74b7c07e96 Add MIDI class driver, update MIDI device demo to use the new USB class driver. All device demos/projects have now been converted to the new library class drivers, although documentation is yet to be completed. 2009-06-01 12:01:53 +00:00
Dean Camera d1e5266036 Commit of new class abstraction APIs for all device demos other than the MIDI demo - not documented yet. 
Removed scheduler and memory allocation libraries.

Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated).

Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.
