|
|
* cdl/io_can.cdl: support for add/remove compiler flags
|
| 4 |
|
|
* doc/can.sgml, doc/can_driver_doc.html: updated doc reflecting API
|
| 5 |
|
|
changes (range/mask filtering, listen-only mode, return values for
|
| 6 |
|
|
xmt_msg/rcv_event, new flags).
|
| 7 |
|
|
* include/can.h: given in a match the types of function pointers for
|
| 8 |
|
|
can_callbacks_t according to the changes made in can.c.
|
| 9 |
|
|
* include/canio.h: flags field in event enlarged to 32 bits to fit
|
| 10 |
|
|
new events 'CYGNUM_CAN_EVENT_ERR_ACTIVE' and
|
| 11 |
|
|
'CYGNUM_CAN_EVENT_OVERRUN_RX_HW'. Made a 'flag' typedef.
|
| 12 |
|
|
cyg_can_event fields reordered so flags size change keeps events the
|
| 13 |
|
|
same size. Defined new filtering capabilities (range/mask). New
|
| 14 |
|
|
convenience macro CYGNUM_CAN_EVENT_ALL. New listen-only mode.
|
| 15 |
|
|
* src/can.c: can_rcv_event() and can_xmt_msg() now returns cyg_bool
|
| 16 |
|
|
(were 'void'). flags using cyg_can_event_flags_t type.

* include/can.h: EOF footer: s/SERIAL/CAN/.
|
| 22 |
|
|
* src/can.c: can_set_config(): Fixed key's name to drain output:
|
| 23 |
|
|
s{CYG_IO_GET_CONFIG_SERIAL_OUTPUT_DRAIN
|
| 24 |
|
|
}{CYG_IO_SET_CONFIG_CAN_OUTPUT_DRAIN}.

|
|
* doc/can.sgml: Callback on event documentation.
|
| 29 |
|
|
* src/can.c: Change one wakeup to callback in a comment.
|
| 30 |
|
|
* include/canio.h: changed cyg_addrword_t to CYG_ADDRWORD so
|
| 31 |
|
|
can will compile without the kernel.

|
|
|
| 36 |
|
|
* cdl/io_can.cdl: Added option CYGOPT_IO_CAN_SUPPORT_CALLBACK
|
| 37 |
|
|
|
| 38 |
|
|
* include/canio.h: Added struct cyg_can_callback_cfg for setting
|
| 39 |
|
|
callback configurations.
|
| 40 |
|
|
|
| 41 |
|
|
* include/can.h: Added declaration and initialization of callback
|
| 42 |
|
|
configuration in struct can_channel.
|
| 43 |
|
|
|
| 44 |
|
|
* src/can.c: Added callback configuration changing and
|
| 45 |
|
|
application function call.

|
| 48 |
|
|
|
| 49 |
|
|
* cdl/io_can.cdl: Added interface CYGINT_IO_CAN_CHANNELS for
|
| 50 |
|
|
counting available CAN channels
|
| 51 |
|
|
|
| 52 |
|
|
* include/canio.h: Changed type cyg_can_msgbuf_info. The two
|
| 53 |
|
|
fields are 16 bit now because device drivers may support more
|
| 54 |
|
|
than 256 message buffers (i.e. the LPC2xxx CAN driver)
|
| 55 |
|
|
|
| 56 |
|
|
2007-06-20 Uwe Kindler
|
| 57 |
|
|
|
| 58 |
|
|
* test/can_filter: Changed filter loop counter from cyg_uint8 to
|
| 59 |
|
|
cyg_uint16 because LPC2xxx CAN driver supports more than 256
|
| 60 |
|
|
message buffers.
|
| 61 |
|
|
|
| 62 |
|
|
2007-03-23 Uwe Kindler
|
| 63 |
|
|
|
| 64 |
|
|
* cdl/io_can.cdl: Added several interfaces for implementation by
|
| 65 |
|
|
device drivers.
|
| 66 |
|
|
Moved several configuration options from device drivers to the
|
| 67 |
|
|
generic CAN driver. With this design a device driver does not
|
| 68 |
|
|
need to provide all configuration options in its CDL file - it
|
| 69 |
|
|
simply needs to implement the provided interfaces. The drawback
|
| 70 |
|
|
of this decicsion is, that it is not possible to control these
|
| 71 |
|
|
options independently for several CAN devices. (But most platforms
|
| 72 |
|
|
will have only 1 channel)
|
| 73 |
|
|
Added configuration option CYGBLD_IO_CAN_EXTRA_TESTS. This option
|
| 74 |
|
|
enables the build of the interactive CAN tests.
|
| 75 |
|
|
|
| 76 |
|
|
* test/can_filter: Added interactive message filtering test
|
| 77 |
|
|
|
| 78 |
|
|
* test/can_hdi: Added interactive hardware description interface
|
| 79 |
|
|
test
|
| 80 |
|
|
|
| 81 |
|
|
* test/can_load: Added interactive message handling (reception,
|
| 82 |
|
|
transmission) test.
|
| 83 |
|
|
|
| 84 |
|
|
* test/can_remote: Added interactive remote response buffer test
|
| 85 |
|
|
|
| 86 |
|
|
* test/can_tx: Added interactive basic TX test. All tests are not
|
| 87 |
|
|
part of the eCos test framework because they are interactive. That
|
| 88 |
|
|
means, they require interaction with another user controlled
|
| 89 |
|
|
CAN node.
|
| 90 |
|
|
|
| 91 |
|
|
* include/can.h: Added identifier masks for standard and extended
|
| 92 |
|
|
identifiers.
|
| 93 |
|
|
Added the line #include CYGDAT_IO_CAN_DEVICE_INL. This enables a
|
| 94 |
|
|
device driver to provide an own device inline file. In this inline
|
| 95 |
|
|
file the driver may define own data types for CAN messages (for
|
| 96 |
|
|
internal storage of CAN messages (see AT91SAM7 CAN driver))
|
| 97 |
|
|
|
| 98 |
|
|
* include/canio.h: Added baudrate CYGNUM_CAN_KBAUD_AUTO - support of
|
| 99 |
|
|
automatic baudrate detection if a driver supports such a feature.
|
| 100 |
|
|
Added state CYGNUM_CAN_STATE_CONFIG and mode CYGNUM_CAN_MODE_CONFIG.
|
| 101 |
|
|
The application may use these identifiers to set the CAN device into
|
| 102 |
|
|
a state where it is safe to add/remove/configure message buffers.
|
| 103 |
|
|
Added union data type cyg_can_msg_data. With this data type a 4 byte
|
| 104 |
|
|
alignment of message data is guaranteed, an byte, word and dword
|
| 105 |
|
|
access to the data is possible and an assignment of two CAN datas are
|
| 106 |
|
|
possible now.
|
| 107 |
|
|
cyg_can_message now uses cyg_can_msg_data union for CAN data.
|
| 108 |
|
|
Replaced SW-Filt flag by autobaud flag in HDI.
|
| 109 |
|
|
Added CAN message access macros for read/write acces of CAN message
|
| 110 |
|
|
structures. These macros hide implementation of CAN message from
|
| 111 |
|
|
application.
|
| 112 |
|
|
|
| 113 |
|
|
* src/can.c: Added support for device driver defined CAN message
|
| 114 |
|
|
data types
|
| 115 |
|
|
|
| 116 |
|
|

|
2006-12-13 Uwe Kindler
|
| 121 |

|
| 131 |
|
|
calling into low level hardware driver.
|
| 132 |
|
|
|

|
2006-02-15 Uwe Kindler
|
| 134 |
|
|
|
| 135 |
|
|
* include/can_io.h Added message buffer configuration identifier:
|
| 136 |
|
|
CYGNUM_CAN_MSGBUF_RESET_ALL, CYGNUM_CAN_MSGBUF_RX_FILTER_ALL ...
|
| 137 |
|
|
Added cfg_id field to cyg_can_msgbuf_cfg data structure.
|
| 138 |
|
|
|
| 139 |
|
|
2005-09-11 Uwe Kindler
|
| 140 |
|
|
|
| 141 |
|
|
* include/can_io.h Added support for get_config to CAN_LOWLEVEL_FUNS
|
| 142 |
|
|
structure.
|
| 143 |
|
|
Added additional CAN events.
|
| 144 |
|
|
Added support for can state (cyg_can_state) and CAN mode (cyg_can_mode).
|
| 145 |
|
|
Changed data type of cyg_can_buf_info_t data structure from cyg_int32
|
| 146 |
|
|
to cyg_uint32.
|
| 147 |
|
|
Added support for message box configuration (cyg_can_msgbuf_info).
|
| 148 |
|
|
Added support for message filtering (cyg_cn_filter).
|
| 149 |
|
|
Renamed cyg_can_rtr_buf to cyg_can_remote_buf.
|
| 150 |
|
|
Renamed CYGNUM_CAN_RTR_BUF_NA and CYGNUM_CAN_RTR_BUF_INIT to
|
| 151 |
|
|
CYGNUM_CAN_MSGBUF_NA and CYGNUM_CAN_MSGBUF_INIT because they are
|
| 152 |
|
|
also used for message filtering.
|
| 153 |
|
|
Added support for hardware description interface.
|
| 154 |
|
|
Added support for CYG_IO_SET_CONFIG_CAN_INPUT_FLUSH,
|
| 155 |
|
|
CYG_IO_SET_CONFIG_CAN_OUTPUT_FLUSH and CYG_IO_GET_CONFIG_SERIAL_OUTPUT_DRAIN.
|
| 156 |
|
|
|
| 157 |
|
|
* doc/can_driver_doc.html Additional configuration options
|
| 158 |
|
|
documented.
