开放源码实时操作系统源码.

2007-08-23 Alexey Shusharin <[e-mail]>
	
	* doc/can.sgml: Callback on event documentation.
	* src/can.c:  Change one wakeup to callback in a comment.
	* include/canio.h: changed cyg_addrword_t to CYG_ADDRWORD so
	  can will compile without the kernel.
	
2007-08-06 Alexey Shusharin <[e-mail]>
           Andrew Lunn <[e-mail]>
	
	* cdl/io_can.cdl: Added option CYGOPT_IO_CAN_SUPPORT_CALLBACK
      
	* include/canio.h: Added struct cyg_can_callback_cfg for setting
          callback configurations.
       
	* include/can.h: Added declaration and initialization of callback 
          configuration in struct can_channel.
       
	* src/can.c: Added callback configuration changing and
          application function call.

2007-07-02 Uwe Kindler <[e-mail]>
    
	* cdl/io_can.cdl: Added interface CYGINT_IO_CAN_CHANNELS for
	  counting available CAN channels
      
	* include/canio.h: Changed type cyg_can_msgbuf_info. The two
	  fields are 16 bit now because device drivers may support more
	  than 256 message buffers (i.e. the LPC2xxx CAN driver)
    
2007-06-20  Uwe Kindler  <[e-mail]>

	* test/can_filter: Changed filter loop counter from cyg_uint8 to
	  cyg_uint16 because LPC2xxx CAN driver supports more than 256
	  message buffers.

2007-03-23  Uwe Kindler  <[e-mail]>

	* cdl/io_can.cdl: Added several interfaces for implementation by
	  device drivers.
	  Moved several configuration options from device drivers to the
	  generic CAN driver. With this design a device driver does not
	  need to provide all configuration options in its CDL file - it
	  simply needs to implement the provided interfaces. The drawback
	  of this decicsion is, that it is not possible to control these
	  options independently for several CAN devices. (But most platforms
	  will have only 1 channel)
	  Added configuration option CYGBLD_IO_CAN_EXTRA_TESTS. This option
	  enables the build of the interactive CAN tests.
	  
	* test/can_filter: Added interactive message filtering test
	
	* test/can_hdi: Added interactive hardware description interface
	  test
	  
	* test/can_load: Added interactive message handling (reception,
	  transmission) test.
	  
	* test/can_remote: Added interactive remote response buffer test
	  
	* test/can_tx: Added interactive basic TX test. All tests are not
	  part of the eCos test framework because they are interactive. That
	  means, they require interaction with another user controlled 
	  CAN node.
	  
	* include/can.h: Added identifier masks for standard and extended
	  identifiers.
	  Added the line #include CYGDAT_IO_CAN_DEVICE_INL. This enables a
	  device driver to provide an own device inline file. In this inline
	  file the driver may define own data types for CAN messages (for
	  internal storage of CAN messages (see AT91SAM7 CAN driver))

	* include/canio.h: Added baudrate CYGNUM_CAN_KBAUD_AUTO - support of 
	  automatic baudrate detection if a driver supports such a feature.
	  Added state CYGNUM_CAN_STATE_CONFIG and mode CYGNUM_CAN_MODE_CONFIG.
	  The application may use these identifiers to set the CAN device into
	  a state where it is safe to add/remove/configure message buffers.
	  Added union data type cyg_can_msg_data. With this data type a 4 byte
	  alignment of message data is guaranteed, an byte, word and dword 
	  access to the data is possible and an assignment of two CAN datas are
	  possible now.
	  cyg_can_message now uses cyg_can_msg_data union for CAN data.
	  Replaced SW-Filt flag by autobaud flag in HDI.
	  Added CAN message access macros for read/write acces of CAN message
	  structures. These macros hide implementation of CAN message from 
	  application.
 
	* src/can.c: Added support for device driver defined CAN message 
	  data types

2006-12-19  Sergei Gavrikov  <[e-mail]>

	* doc/can.sgml: Correctly close para tag.

2006-12-13  Uwe Kindler  <[e-mail]>

	* doc/can.sgml: CAN driver SGML documentation added.

2006-08-25  Gary Thomas  <[e-mail]>

	* cdl/io_can.cdl: Set parent for more intuitive ConfigTool layout.

2006-03-27  Uwe Kindler  <[e-mail]>

	* src/can.c can_rcv_event() Clear the flag field in new event before
	calling into low level hardware driver.

2006-02-15  Uwe Kindler  <[e-mail]>

	* include/can_io.h Added message buffer configuration identifier:
	CYGNUM_CAN_MSGBUF_RESET_ALL, CYGNUM_CAN_MSGBUF_RX_FILTER_ALL ...
	Added cfg_id field to cyg_can_msgbuf_cfg data structure.

2005-09-11  Uwe Kindler  <[e-mail]>

	* include/can_io.h Added support for get_config to CAN_LOWLEVEL_FUNS
	structure. 
	Added additional CAN events. 
	Added support for can state (cyg_can_state) and CAN mode (cyg_can_mode).  
	Changed data type of cyg_can_buf_info_t data structure from cyg_int32 
	to cyg_uint32. 
	Added support for message box configuration (cyg_can_msgbuf_info).
	Added support for message filtering (cyg_cn_filter). 
	Renamed cyg_can_rtr_buf to cyg_can_remote_buf. 
	Renamed CYGNUM_CAN_RTR_BUF_NA and CYGNUM_CAN_RTR_BUF_INIT to 
	CYGNUM_CAN_MSGBUF_NA and CYGNUM_CAN_MSGBUF_INIT because they are
	also used for message filtering. 
	Added support for hardware description interface. 
	Added support for CYG_IO_SET_CONFIG_CAN_INPUT_FLUSH,
	CYG_IO_SET_CONFIG_CAN_OUTPUT_FLUSH and CYG_IO_GET_CONFIG_SERIAL_OUTPUT_DRAIN.
	
	* doc/can_driver_doc.html Additional configuration options
	documented.

	* Generic CAN driver package created
