00001 /* $Id:$ 00002 00003 1.13- 2 Mar 2013 00004 00005 * Update RESERVED9 to DMAREQSEL in SETUP.cpp 00006 Thanks Bryce Chee for pointing it out. 00007 00008 1.12- 14 Mar 2011 00009 00010 * Added example4.h that demonstrates alternately sending 00011 two buffers (double buffering) to the DAC. All those 00012 people building MP3 players may find this of interest. 00013 00014 1.11- 13 Mar 2011 00015 00016 * Fixed a silly typo in the documentation of example3.h 00017 00018 1.10- 13 Mar 2011 00019 00020 * The rescheduling showed the timer being stopped and restarted 00021 to perform a new scheduled grab. This was changed to show the 00022 timer free running and the reschedules being setup. 00023 00024 1.9 - 13 Mar 2011 00025 00026 * Improved example3.h to add rescheduling additional grabs 00027 based on the timer setup. 00028 00029 1.8 - 13 Mar 2011 00030 00031 * Renamed example files to .h 00032 * Added pseudo g2m and m2g transferTypes to support GPIO 00033 "memory moves" but triggered by peripheral timer. To 00034 support this new operating mode added example3.h 00035 00036 1.7 - 13 Mar 2011 00037 00038 * Remove the test at the beginning of the channel setup. 00039 00040 1.6 - 8 Mar 2011 00041 00042 * Fixed a typo bug. Reported by Wim van der Vegt 00043 http://mbed.org/forum/mbed/topic/1798/?page=1#comment-9845 00044 00045 1.5 - 5 Feb 2011 00046 00047 * Found a bug in the NXP library that I had copied over. 00048 http://mbed.org/forum/mbed/topic/1798 00049 * Added example2.cpp to support that forum thread. 00050 00051 1.4 - 23/11/2010 00052 00053 * Added some extra overloaded methods to make calling certain 00054 userland API methods simpler. 00055 00056 1.3 - 23/10/2010 00057 00058 * Added the LLI class wrapper. 00059 * Added checking channel's LLI for non-null before auto-disable 00060 of a channel with the ISR. 00061 * Tested with MODSERIAL which is now natively MODDMA "aware". 00062 MODSERIAL can now, using MODDMA, send blocks of bytes out 00063 of it's TX port under DMA control. 00064 00065 1.2 - 23/10/2010 00066 00067 * Improved the IRQ callback attachment API to make 00068 easier attachments when creating configurations. 00069 00070 1.1 - 23/10/2010 00071 00072 * Tidied up example1.cpp 00073 * Removed some unneeded methoids that cause compiler errs. 00074 00075 1.0 - 23/11/2010 00076 00077 * First release 00078 00079 */
