               Dynamic C for Rabbit Release Notes

*****************************************************************
*****************************************************************
VERSION 10.70

NEW FEATURES

- New XBee/ZigBee driver.

  A new XBee/ZigBee driver and standard sample programs are
  provided. See Samples\XBee\ReadMe.txt and the latest version of
  "Dynamic C - An Introduction To ZigBee" for more information.

- MiniCore RCM6600W and RCM6650W support.

  The MiniCore RCM6600W family supports both WiFi (on-core) and
  Ethernet (off-core) network interfaces.

  The MiniCore RCM6600W has a 1 MB serial boot flash while the
  the RCM6650W has a 4MB serial boot flash.  Using the API
  from sflash.lib, on the RCM6650W up to 3MB is available for
  data storage.  See sample programs in Samples\RCM6600W.

- Custom definition of ORG_PLACE_USERDATA_IN_RAMx allows an
  application to relocate the optional user data memory org into
  a specified RAM device.

  To specify the user data memory org's RAM device, add:
     ORG_PLACE_USERDATA_IN_RAMx = RAMx
  into Dynamic C's Project Options' Defines tab, where integer
  RAMx is one of 1, 2, or 3, as appropriate to the application's
  Rabbit board type and compile mode.

  If the user specifies an in-range but non-existent RAMx device
  then a rather cryptic error message will result. For example,
  specifying that the user data buffer should be relocated into
  RAM2 when compiling to an RCM4000 results in the following
  error message: "userdata_buff: This reference has no
  corresponding definition."

  For applications which utilize the optional user data memory
  org, Dynamic C's Project Options' Defines tab is a convenient
  spot to set the required size. For example, adding:
     _SOS_USERDATA = 0x1000
  specifies a 0x1000 byte (4KB) user data memory org.

BUG FIXES

Compiler Bugs

GUI Bugs

Library Bugs
- Defect #34603. DMA functionality in SERLINK.LIB is updated to
  support Rabbit 5000 and 6000 CPUs.
- Defect #37681. TAT11R and TAT12R internal register addresses
  are now conditionally defined in SYSIODEFS.LIB for Rabbit 6000
  CPUs.
- Defect #38379. DMA functionality in RS232.LIB is updated to
  support Rabbit 5000 and 6000 CPUs.
- Defect #38777. When uC/OS-II is used, SERLINK.LIB's ISR now
  prevents task switching while interrupt processing continues
  with reenabled interrupts.
- Defect #39302. In modbus_master.lib, custom _initMBMpacket()
  functionality is restored for TCP-only Modbus master boards. A
  library function stub is now provided, along with function help.
- Defect #39461. In DMAETH100.LIB's internal *._havelink()
  function, errant restart of autonegotiation is prevented when
  autonegotiation is disabled.
- Defect #39750. All memory orgs located in a battery-backable
  SRAM are now properly identified in memory_layout.lib as being
  BB, with regard to both xalloc usage and in the program's MAP
  file. In particular, the RCM6750/60's battery-backable external
  SRAM's memory org is now marked as BB.
- Defect #39751. On RCM56xxW boards, the FAT file system buffers
  have been fixed to the top of the battery-backable RAM org.
  This prevents other BB memory orgs, such as the optional user
  data org, from changing the location of the FAT buffers.
- Defect #40496. In UCOS2.LIB, a number of global variables were
  declared inside a module header, causing data storage
  generation at "#use ucos2.lib" library scan time.
- Defect #41149. The informational error_message() and
  _error_message() functions in errors.lib have been fixed to
  prevent a potential hang problem when an error number is
  specified for which no error message exists.
- Defect #41653. The ROOT_SIZE_4K macro value must be unsigned,
  else values greater than 7 will cause a signed (negative)
  memory org size problem. The check in StdBios.c now enforces
  unsigned ROOT_SIZE_4K values greater than 7.

OTHER FUNCTIONAL CHANGES

- Dynamic C's original XBee support libraries (xbee_api.lib, etc.)
  and samples are obsolete and are removed from the Dynamic C
  10.70 release. Users are encouraged to port legacy XBee
  applications to the new XBee/ZigBee driver, however, where
  porting is not practical the application should remain on
  Dynamic C 10.66 or prior version.

- The DMAETH100_AUTO_NEG_TIMEOUT macro is deprecated. Rabbit 5000
  or 6000 built-in Ethernet applications which use a custom
  definition for this macro should instead define one or both of
  the DMAETH100_LINKFAIL_TIMEOUT or DMAETH100_LINKDOWN_TIMEOUT
  macros. The *LINKFAIL* macro value determines the PHY powered-
  up time out for link-failed detection. The *LINKDOWN* macro
  value determines the PHY powered-down idle time-out for no-
  connect Ethernet current reduction. The default value for each
  of the *LINK* macros is 4000 milliseconds, which results in a
  50% powered-up vs. powered-down duty cycle when e.g. Ethernet
  is not connected.
