General:

DCP is not considered a part of the Code Composer or Code Composer Studio products sold by TI. Instead it is a free support tool providing additional application support to TI customers. As this all standard disclaimers for application support from TI apply to the tool itself and all software generated by using the tool. CCS maintenance and warranty claims do not apply for DCP.

Features of Current Version:

• Fully implemented graphical user interface
• Generates or changes files depending on user input:
• DC_CONF.H:  All #define constants according to user configuration for all data converters and the DSP
• Txxxx_FN.H: Data converter software object type definitions and in-line versions of driver functions for device xxxx
• Txxxx_OB.C: Data converter objects definition with initialization and driver functions for device xxxx. This drivers should not be confused with DSP/BIOS drivers.
• TIDC_API.C & TIDC_API.H: Data Converter API. A high level interface for using the DCP drivers. It is not required to use the API as they add a level of indirection. For performance reasons you might want to directly call device driver functions
• All devices added by the user and their options are stored within the CCS workspace. Once saved this allows to get a user configuration from storage.
• It is possible to enter a device name without traversing the selection tree by entering the device name or selecting it from the drop-down list.
• See help files for more information.

What's New in this Version:

• Support for the following new devices is added:
  • ADS803 (C6200/C6700, C6400) with DMA support
  • ADS804 (C6200/C6700, C6400) with DMA support
  • ADS805 (C6200/C6700, C6400) with DMA support
  • ADS1625 (C5500, C6200/C6700, C6400)  with DMA support
  • ADS7861 (C2800, C5400, C5500, C6200/C6700, C6400)
  • ADS8361 (C2800, C5400, C5500, C6200/C6700, C6400)
  • ADS8381 (C5500, C6200/C6700, C6400)  with DMA support
  • ADS8383 (C5500, C6200/C6700, C6400)  with DMA support
  • AFE1230 (C5400, C5500)
  • PCM4202 (C5400, C5500, C6200/C6700, C6400)
• Support for the TMS320C2800 DSP platform
  • Please note that the drivers for the TMS320C2800 DSP platform depend on the "C281x C/C++ Header Files", literature  number SPRC097, which can be downloaded from TI's website at http://focus.ti.com/docs/tool/toolfolder.jhtml?PartNumber=SPRC097
• Updated the following drivers:
  • ADS1605: (C5500, C6200/C6700, C6400)  with DMA support
  • DAC8501: Added support for the C2800
  • DAC8531: Added support for the C2800

DCP 3.3 Device Support Table

C =  GUI and register contents generation (dc_conf.h)
        These devices are marked light gray in the selection tree

Known Issues:

• If the user changes the automatically generated header files, especially the auto code start and end markers, a message might appear that states that there is a problem with this markers. The Plug-In will not change the text in this case and just insert the new  text to the beginning of the file. In this case compile errors may appear due to double definitions. In this case, please edit the files manually and delete the old contents.
• If the user builds a project file and moves this to a new directory without files, DCP will assume that the files to created files exist. It will therefore issue a warning "Cannot re-open file". Just press OK as these file(s) will then be generated correctly.
• The drivers generates for the TMS320C6200, TMS320C6700 and TMS320C6400 DSP platforms do not support the big endian mode.
• DCP help file information for a few data converter devices is incomplete. In this case a web link is provided that points to the data converter information folder on TI's external web site. There the full data sheet and additional device information is available.
• Not all devices feature a full drivers. For some, only the register contents is generated based on the settings in the GUI. These devices are marked with "C" in the table above and are grey in the selection tree of the tool.
• ADS803/804/805, ADS1605/1625, ADS8381/8383 and ADS8322 / ADS8323 work only for DSPs with EDMA support (i.e. not for the TMS320C620x and the TMS320C6701)
