00001 /* $Id:$ 00002 00003 1.12- 14 Mar 2011 00004 00005 * Added example4.h that demonstrates alternately sending 00006 two buffers (double buffering) to the DAC. All those 00007 people building MP3 players may find this of interest. 00008 00009 1.11- 13 Mar 2011 00010 00011 * Fixed a silly typo in the documentation of example3.h 00012 00013 1.10- 13 Mar 2011 00014 00015 * The rescheduling showed the timer being stopped and restarted 00016 to perform a new scheduled grab. This was changed to show the 00017 timer free running and the reschedules being setup. 00018 00019 1.9 - 13 Mar 2011 00020 00021 * Improved example3.h to add rescheduling additional grabs 00022 based on the timer setup. 00023 00024 1.8 - 13 Mar 2011 00025 00026 * Renamed example files to .h 00027 * Added pseudo g2m and m2g transferTypes to support GPIO 00028 "memory moves" but triggered by peripheral timer. To 00029 support this new operating mode added example3.h 00030 00031 1.7 - 13 Mar 2011 00032 00033 * Remove the test at the beginning of the channel setup. 00034 00035 1.6 - 8 Mar 2011 00036 00037 * Fixed a typo bug. Reported by Wim van der Vegt 00038 http://mbed.org/forum/mbed/topic/1798/?page=1#comment-9845 00039 00040 1.5 - 5 Feb 2011 00041 00042 * Found a bug in the NXP library that I had copied over. 00043 http://mbed.org/forum/mbed/topic/1798 00044 * Added example2.cpp to support that forum thread. 00045 00046 1.4 - 23/11/2010 00047 00048 * Added some extra overloaded methods to make calling certain 00049 userland API methods simpler. 00050 00051 1.3 - 23/10/2010 00052 00053 * Added the LLI class wrapper. 00054 * Added checking channel's LLI for non-null before auto-disable 00055 of a channel with the ISR. 00056 * Tested with MODSERIAL which is now natively MODDMA "aware". 00057 MODSERIAL can now, using MODDMA, send blocks of bytes out 00058 of it's TX port under DMA control. 00059 00060 1.2 - 23/10/2010 00061 00062 * Improved the IRQ callback attachment API to make 00063 easier attachments when creating configurations. 00064 00065 1.1 - 23/10/2010 00066 00067 * Tidied up example1.cpp 00068 * Removed some unneeded methoids that cause compiler errs. 00069 00070 1.0 - 23/11/2010 00071 00072 * First release 00073 00074 */
