AjK 14:3c3b87617bfe 15
AjK 14:3c3b87617bfe 16 * Fixed a bug in __putc() that caused the output buffer pointer to
AjK 14:3c3b87617bfe 17 become corrupted.
AjK 14:3c3b87617bfe 18
AjK 13:70bb7c1769fa 19 1.13 - 20/01/2011

AjK 12:8c7394e2ae7f 24 1.12 - 20/01/2011
AjK 12:8c7394e2ae7f 25
AjK 12:8c7394e2ae7f 26 * Added new "autoDetectChar()" function. To use:-
AjK 12:8c7394e2ae7f 27 1st: Add a callback to invoke when the char is detected:-
AjK 12:8c7394e2ae7f 28 .attach(&detectedChar, MODSERIAL::RxAutoDetect);
AjK 12:8c7394e2ae7f 29 2nd: Send the char to detect.
AjK 12:8c7394e2ae7f 30 .autoDectectChar('\n');
AjK 12:8c7394e2ae7f 31 Whenever that char goes into the RX buffer your callback will be invoked.
AjK 12:8c7394e2ae7f 32 Added example2.cpp to demo a simple messaging system using this auto feature.

AjK 11:a93a62eeeb9d 35 1.11 - 23/11/2010
AjK 11:a93a62eeeb9d 36
AjK 11:a93a62eeeb9d 37 * Fixed a minor issue with 1.10 missed an alteration of name change.
AjK 11:a93a62eeeb9d 38
AjK 10:725fe81aa9ff 39 1.10 - 23/11/2010
AjK 10:725fe81aa9ff 40
AjK 10:725fe81aa9ff 41 * Reanme the DMA callback from attach_dma_complete() to attach_dmaSendComplete()
AjK 10:725fe81aa9ff 42
AjK 9:b3cdae80e7a9 43 1.9 - 23/11/2010
AjK 9:b3cdae80e7a9 44
AjK 9:b3cdae80e7a9 45 * Added support for DMA sending of characters. Required is
AjK 9:b3cdae80e7a9 46 the MODDMA library module:-
AjK 9:b3cdae80e7a9 47 http://mbed.org/users/AjK/libraries/MODDMA/latest
AjK 9:b3cdae80e7a9 48 See example_dma.cpp for more information.
AjK 9:b3cdae80e7a9 49
AjK 8:775f860e94d3 50 1.8 - 22/11/2010
AjK 8:775f860e94d3 51
AjK 8:775f860e94d3 52 * Added code so that if a buffer is set to zero length then
AjK 8:775f860e94d3 53 MODSERIAL defaults to just using the FIFO for that stream
AjK 8:775f860e94d3 54 thus making the library "fall back" to teh same operation
AjK 8:775f860e94d3 55 that the Mbed Serial library performs.
AjK 8:775f860e94d3 56 * Removed dmaSend() function that should have been removed
AjK 8:775f860e94d3 57 at 1.7
AjK 8:775f860e94d3 58
AjK 7:ffa4a7cb7f8d 59 1.7 - 21/11/2010
AjK 7:ffa4a7cb7f8d 60
AjK 7:ffa4a7cb7f8d 61 * Remove the DMA enum from MODSERIAL.h as it's not currently
AjK 7:ffa4a7cb7f8d 62 ready for release.
AjK 7:ffa4a7cb7f8d 63 * Added page doxygen comments.
AjK 7:ffa4a7cb7f8d 64
AjK 6:c8f77fe1cc10 65 1.6 - 21/11/2010
AjK 6:c8f77fe1cc10 66
AjK 6:c8f77fe1cc10 67 * Version 1.5 solved a blocking problem on putc() when called
AjK 6:c8f77fe1cc10 68 from another ISR. However, isr_tx() invokes a callback of it's
AjK 6:c8f77fe1cc10 69 own when a byte is tranferred from TX buffer to TX FIFO. User
AjK 6:c8f77fe1cc10 70 programs may interpret that as an IRQ callback. That's an ISR
AjK 6:c8f77fe1cc10 71 call from within an existing ISR which is not good. So the
AjK 6:c8f77fe1cc10 72 TxIrq callback from isr_tx is now conditional. It will only
AjK 6:c8f77fe1cc10 73 be called when isr_tx() is actually within it's own ISR and
AjK 6:c8f77fe1cc10 74 not when called from alternate ISR handlers.
AjK 6:c8f77fe1cc10 75
AjK 5:8365c4cf8f33 76 1.5 - 21/11/2010
AjK 5:8365c4cf8f33 77
AjK 5:8365c4cf8f33 78 * Calling putc() (or any derived function that uses it like
AjK 5:8365c4cf8f33 79 printf()) while inside an interrupt service routine can
AjK 5:8365c4cf8f33 80 cause the system to lock up if the TX buffer is full. This
AjK 5:8365c4cf8f33 81 is because bytes are only transferred from the TX buffer to
AjK 5:8365c4cf8f33 82 the TX FIFO via the TX ISR. If we are, say in an RX ISR already,
AjK 5:8365c4cf8f33 83 then the TX ISR will never trigger. The TX buffer stays full and
AjK 5:8365c4cf8f33 84 there is never space to putc() the byte. So, while putc() blocks
AjK 5:8365c4cf8f33 85 waiting for space it calls isr_tx() to ensure if TX FIFO space
AjK 5:8365c4cf8f33 86 becomes available it will move bytes from the TX buffer to TX
AjK 5:8365c4cf8f33 87 FIFO thus removing the blocking condition within putc().
AjK 5:8365c4cf8f33 88
AjK 4:28de979b77cf 89 1.4 - 21/11/2010
AjK 4:28de979b77cf 90
AjK 4:28de979b77cf 91 * Removed all the new DMA code. I wish mbed.org had proper SVN
AjK 4:28de979b77cf 92 versioning, I'm use to working in HEAD and BRANCHES after I've
AjK 4:28de979b77cf 93 released a project. Getting bug reports in current releases
AjK 4:28de979b77cf 94 while trying to dev new code is hard to manage without source
AjK 4:28de979b77cf 95 control of some type!
AjK 4:28de979b77cf 96
AjK 2:b936b4acbd92 97 1.3 - 21/11/2010
AjK 2:b936b4acbd92 98
AjK 2:b936b4acbd92 99 * Fixed a macro problem with txIsBusy()
AjK 2:b936b4acbd92 100 * Started adding code to use "block data" sending using DMA
AjK 3:0f10f536456e 101 * Removed #include "IOMACROS.h"
AjK 1:b7e435fbfe8e 102
AjK 2:b936b4acbd92 103 1.2 - 21/11/2010
AjK 2:b936b4acbd92 104
AjK 2:b936b4acbd92 105 * Removed unsed variables from flushBuffer()
AjK 2:b936b4acbd92 106 * Fixed a bug where both RX AND TX fifos are cleared/reset
AjK 2:b936b4acbd92 107 when just TX OR RX should be cleared.
AjK 2:b936b4acbd92 108 * Fixed a bug that cleared IIR when in fact it should be left
AjK 2:b936b4acbd92 109 alone so that any pending interrupt after flush is handled.
AjK 2:b936b4acbd92 110 * Merged setBase() into init() as it wasn't required anywhere else.
AjK 2:b936b4acbd92 111 * Changed init() to enforce _uidx is set by Serial to define the _base
AjK 2:b936b4acbd92 112 address of the Uart in use.
AjK 2:b936b4acbd92 113
AjK 1:b7e435fbfe8e 114 1.1 - 20/11/2010
AjK 1:b7e435fbfe8e 115
AjK 1:b7e435fbfe8e 116 * Added this file
AjK 1:b7e435fbfe8e 117 * Removed cruft from GETC.cpp
AjK 1:b7e435fbfe8e 118 * "teh" should be "the", why do my fingers do that?
AjK 1:b7e435fbfe8e 119
AjK 1:b7e435fbfe8e 120 1.0 - 20/11/2010
AjK 1:b7e435fbfe8e 121
AjK 1:b7e435fbfe8e 122 * First release.
