00038     * Bug fix, not blocking on transmit
00039       by Erik Petrich, http://mbed.org/forum/bugs-suggestions/topic/2200
00040       
00041 1.19    20 April 2011
00042 
00043     * Fixed some doxygen comment bugs.
00044     
00045 1.18    20 April 2011
00046 
00047     * All callbacks now use MODSERIAL_callback (rather than Mbed's FunctionPointer[1] type)
00048       to store and invoke it's callbacks. This allows MODSERIAL to pass a parameter
00049       to callbacks. The function prototype is now void func(MODSERIAL_IRQ_INFO *q).
00050     * Callbacks now pass a pointer to a MODSERIAL_IRQ_INFO class type.
00051       This class holds a pointer to the MODSERIAL object that invoked the callback
00052       thus freeing callbacks need to use the global variable of the original 
00053       MODSERIAL instance.
00054     * MODSERIAL_IRQ_INFO also declares public functions that are protected within MODSERIAL
00055       thus allowing certain functions to be restricted to callback context only.
00056     * New function MODSERIAL_IRQ_INFO::rxDiscardLastChar() allows an rxCallback function
00057       to remove the character that was just placed into the RX buffer.

00060 
00061 1.17   08/Mar/2011
00062        Fixed a memory leak in the DMA code.
00063        
00064 1.16 - 12 Feb 2011
00065     
00066     * Missed one, doh!
00067 
00068 1.15 - 12 Feb 2011
00069     
00070     * Fixed some typos.
00071     
00072 1.14 - 7 Feb 2011
00073 
00074     * Fixed a bug in __putc() that caused the output buffer pointer to 
00075       become corrupted.
00076 
00077 1.13 - 20/01/2011
00078 
00079     * Added extra documentation.
00080     * Fixed some typos.
00081     
00082 1.12 - 20/01/2011
00083 
00084     * Added new "autoDetectChar()" function. To use:-
00085       1st: Add a callback to invoke when the char is detected:-        
00086         .attach(&detectedChar, MODSERIAL::RxAutoDetect);
00087       2nd: Send the char to detect.
00088         .autoDectectChar('\n');
00089       Whenever that char goes into the RX buffer your callback will be invoked.
00090       Added example2.cpp to demo a simple messaging system using this auto feature.
00091 
00092 
00093 1.11 - 23/11/2010
00094 
00095     * Fixed a minor issue with 1.10 missed an alteration of name change.
00096     
00097 1.10 - 23/11/2010
00098 
00099     * Rename the DMA callback from attach_dma_complete() to attach_dmaSendComplete()
00100     
00101 1.9 - 23/11/2010
00102 
00103     * Added support for DMA sending of characters. Required is
00104       the MODDMA library module:-
00105       http://mbed.org/users/AjK/libraries/MODDMA/latest
00106       See example_dma.cpp for more information.
00107       
00108 1.8 - 22/11/2010
00109 
00110     * Added code so that if a buffer is set to zero length then
00111       MODSERIAL defaults to just using the FIFO for that stream
00112       thus making the library "fall back" to teh same operation
00113       that the Mbed Serial library performs.
00114     * Removed dmaSend() function that should have been removed 
00115       at 1.7
00116     
00117 1.7 - 21/11/2010
00118 
00119     * Remove the DMA enum from MODSERIAL.h as it's not currently 
00120       ready for release.
00121     * Added page doxygen comments.
00122 
00123 1.6 - 21/11/2010
00124 
00125    * Version 1.5 solved a blocking problem on putc() when called 
00126      from another ISR. However, isr_tx() invokes a callback of it's
00127      own when a byte is tranferred from TX buffer to TX FIFO. User
00128      programs may interpret that as an IRQ callback. That's an ISR
00129      call from within an existing ISR which is not good. So the 
00130      TxIrq callback from isr_tx is now conditional. It will only
00131      be called when isr_tx() is actually within it's own ISR and
00132      not when called from alternate ISR handlers.
00133      
00134 1.5 - 21/11/2010
00135 
00136     * Calling putc() (or any derived function that uses it like
00137       printf()) while inside an interrupt service routine can
00138       cause the system to lock up if the TX buffer is full. This
00139       is because bytes are only transferred from the TX buffer to
00140       the TX FIFO via the TX ISR. If we are, say in an RX ISR already,
00141       then the TX ISR will never trigger. The TX buffer stays full and
00142       there is never space to putc() the byte. So, while putc() blocks
00143       waiting for space it calls isr_tx() to ensure if TX FIFO space
00144       becomes available it will move bytes from the TX buffer to TX
00145       FIFO thus removing the blocking condition within putc().
00146 
00147 1.4 - 21/11/2010
00148 
00149     * Removed all the new DMA code. I wish mbed.org had proper SVN
00150       versioning, I'm use to working in HEAD and BRANCHES after I've
00151       released a project. Getting bug reports in current releases
00152       while trying to dev new code is hard to manage without source
00153       control of some type!
00154 
00155 1.3 - 21/11/2010
00156 
00157     * Fixed a macro problem with txIsBusy()
00158     * Started adding code to use "block data" sending using DMA
00159     * Removed #include "IOMACROS.h"
00160     
00161 1.2 - 21/11/2010
00162 
00163     * Removed unsed variables from flushBuffer()
00164     * Fixed a bug where both RX AND TX fifos are cleared/reset 
00165       when just TX OR RX should be cleared.
00166     * Fixed a bug that cleared IIR when in fact it should be left
00167       alone so that any pending interrupt after flush is handled.
00168     * Merged setBase() into init() as it wasn't required anywhere else.
00169     * Changed init() to enforce _uidx is set by Serial to define the _base
00170       address of the Uart in use.
00171         
00172 1.1 - 20/11/2010
00173 
00174     * Added this file
00175     * Removed cruft from GETC.cpp
00176     * "teh" should be "the", why do my fingers do that?
00177 
00178 1.0 - 20/11/2010
00179 
00180     * First release.
