All those + people building MP3 players may find this of interest. + +1.11- 13 Mar 2011 + + * Fixed a silly typo in the documentation of example3.h + +1.10- 13 Mar 2011 + + * The rescheduling showed the timer being stopped and restarted + to perform a new scheduled grab. This was changed to show the + timer free running and the reschedules being setup. + +1.9 - 13 Mar 2011 + + * Improved example3.h to add rescheduling additional grabs + based on the timer setup. + +1.8 - 13 Mar 2011 + + * Renamed example files to .h + * Added pseudo g2m and m2g transferTypes to support GPIO + "memory moves" but triggered by peripheral timer. To + support this new operating mode added example3.h + +1.7 - 13 Mar 2011 + + * Remove the test at the beginning of the channel setup. + +1.6 - 8 Mar 2011 + + * Fixed a typo bug. Reported by Wim van der Vegt + http://mbed.org/forum/mbed/topic/1798/?page=1#comment-9845 + +1.5 - 5 Feb 2011 + + * Found a bug in the NXP library that I had copied over. + http://mbed.org/forum/mbed/topic/1798 + * Added example2.cpp to support that forum thread. + +1.4 - 23/11/2010 + + * Added some extra overloaded methods to make calling certain + userland API methods simpler. + +1.3 - 23/10/2010 + + * Added the LLI class wrapper. + * Added checking channel's LLI for non-null before auto-disable + of a channel with the ISR. + * Tested with MODSERIAL which is now natively MODDMA "aware". + MODSERIAL can now, using MODDMA, send blocks of bytes out + of it's TX port under DMA control. + +1.2 - 23/10/2010 + + * Improved the IRQ callback attachment API to make + easier attachments when creating configurations. + +1.1 - 23/10/2010 + + * Tidied up example1.cpp + * Removed some unneeded methoids that cause compiler errs. + +1.0 - 23/11/2010 + + * First release + +*/
