AjK 20:59c74aaedda2 48 1.19 20 April 2011
AjK 20:59c74aaedda2 49
AjK 20:59c74aaedda2 50 * Fixed some doxygen comment bugs.
AjK 20:59c74aaedda2 51
AjK 18:21ef26402365 52 1.18 20 April 2011
AjK 18:21ef26402365 53
AjK 18:21ef26402365 54 * All callbacks now use MODSERIAL_callback (rather than Mbed's FunctionPointer[1] type)
AjK 18:21ef26402365 55 to store and invoke it's callbacks. This allows MODSERIAL to pass a parameter
AjK 18:21ef26402365 56 to callbacks. The function prototype is now void func(MODSERIAL_IRQ_INFO *q).
AjK 18:21ef26402365 57 * Callbacks now pass a pointer to a MODSERIAL_IRQ_INFO class type.
AjK 18:21ef26402365 58 This class holds a pointer to the MODSERIAL object that invoked the callback
AjK 18:21ef26402365 59 thus freeing callbacks need to use the global variable of the original
AjK 18:21ef26402365 60 MODSERIAL instance.
AjK 18:21ef26402365 61 * MODSERIAL_IRQ_INFO also declares public functions that are protected within MODSERIAL
AjK 18:21ef26402365 62 thus allowing certain functions to be restricted to callback context only.
AjK 18:21ef26402365 63 * New function MODSERIAL_IRQ_INFO::rxDiscardLastChar() allows an rxCallback function
AjK 18:21ef26402365 64 to remove the character that was just placed into the RX buffer.

AjK 17:6c9b57c14868 70
AjK 16:8b1dbf4cce4e 71 1.16 - 12 Feb 2011
AjK 16:8b1dbf4cce4e 72
AjK 16:8b1dbf4cce4e 73 * Missed one, doh!
AjK 16:8b1dbf4cce4e 74
AjK 15:a1d9e745d71e 75 1.15 - 12 Feb 2011
AjK 15:a1d9e745d71e 76
AjK 15:a1d9e745d71e 77 * Fixed some typos.
AjK 15:a1d9e745d71e 78
AjK 14:3c3b87617bfe 79 1.14 - 7 Feb 2011
AjK 14:3c3b87617bfe 80
AjK 14:3c3b87617bfe 81 * Fixed a bug in __putc() that caused the output buffer pointer to
AjK 14:3c3b87617bfe 82 become corrupted.
AjK 14:3c3b87617bfe 83
AjK 13:70bb7c1769fa 84 1.13 - 20/01/2011
AjK 13:70bb7c1769fa 85
AjK 13:70bb7c1769fa 86 * Added extra documentation.
AjK 13:70bb7c1769fa 87 * Fixed some typos.
AjK 13:70bb7c1769fa 88
AjK 12:8c7394e2ae7f 89 1.12 - 20/01/2011
AjK 12:8c7394e2ae7f 90
AjK 12:8c7394e2ae7f 91 * Added new "autoDetectChar()" function. To use:-
AjK 12:8c7394e2ae7f 92 1st: Add a callback to invoke when the char is detected:-
AjK 12:8c7394e2ae7f 93 .attach(&detectedChar, MODSERIAL::RxAutoDetect);
AjK 12:8c7394e2ae7f 94 2nd: Send the char to detect.
AjK 12:8c7394e2ae7f 95 .autoDectectChar('\n');
AjK 12:8c7394e2ae7f 96 Whenever that char goes into the RX buffer your callback will be invoked.
AjK 12:8c7394e2ae7f 97 Added example2.cpp to demo a simple messaging system using this auto feature.
AjK 12:8c7394e2ae7f 98
AjK 12:8c7394e2ae7f 99
AjK 11:a93a62eeeb9d 100 1.11 - 23/11/2010
AjK 11:a93a62eeeb9d 101
AjK 11:a93a62eeeb9d 102 * Fixed a minor issue with 1.10 missed an alteration of name change.
AjK 11:a93a62eeeb9d 103
AjK 10:725fe81aa9ff 104 1.10 - 23/11/2010
AjK 10:725fe81aa9ff 105
AjK 18:21ef26402365 106 * Rename the DMA callback from attach_dma_complete() to attach_dmaSendComplete()
AjK 10:725fe81aa9ff 107
AjK 9:b3cdae80e7a9 108 1.9 - 23/11/2010
AjK 9:b3cdae80e7a9 109
AjK 9:b3cdae80e7a9 110 * Added support for DMA sending of characters. Required is
AjK 9:b3cdae80e7a9 111 the MODDMA library module:-
AjK 9:b3cdae80e7a9 112 http://mbed.org/users/AjK/libraries/MODDMA/latest
AjK 9:b3cdae80e7a9 113 See example_dma.cpp for more information.
AjK 9:b3cdae80e7a9 114
AjK 8:775f860e94d3 115 1.8 - 22/11/2010
AjK 8:775f860e94d3 116
AjK 8:775f860e94d3 117 * Added code so that if a buffer is set to zero length then
AjK 8:775f860e94d3 118 MODSERIAL defaults to just using the FIFO for that stream
AjK 8:775f860e94d3 119 thus making the library "fall back" to teh same operation
AjK 8:775f860e94d3 120 that the Mbed Serial library performs.
AjK 8:775f860e94d3 121 * Removed dmaSend() function that should have been removed
AjK 8:775f860e94d3 122 at 1.7
AjK 8:775f860e94d3 123
AjK 7:ffa4a7cb7f8d 124 1.7 - 21/11/2010
AjK 7:ffa4a7cb7f8d 125
AjK 7:ffa4a7cb7f8d 126 * Remove the DMA enum from MODSERIAL.h as it's not currently
AjK 7:ffa4a7cb7f8d 127 ready for release.
AjK 7:ffa4a7cb7f8d 128 * Added page doxygen comments.
AjK 7:ffa4a7cb7f8d 129
AjK 6:c8f77fe1cc10 130 1.6 - 21/11/2010
AjK 6:c8f77fe1cc10 131
AjK 6:c8f77fe1cc10 132 * Version 1.5 solved a blocking problem on putc() when called
AjK 6:c8f77fe1cc10 133 from another ISR. However, isr_tx() invokes a callback of it's
AjK 6:c8f77fe1cc10 134 own when a byte is tranferred from TX buffer to TX FIFO. User
AjK 6:c8f77fe1cc10 135 programs may interpret that as an IRQ callback. That's an ISR
AjK 6:c8f77fe1cc10 136 call from within an existing ISR which is not good. So the
AjK 6:c8f77fe1cc10 137 TxIrq callback from isr_tx is now conditional. It will only
AjK 6:c8f77fe1cc10 138 be called when isr_tx() is actually within it's own ISR and
AjK 6:c8f77fe1cc10 139 not when called from alternate ISR handlers.
AjK 6:c8f77fe1cc10 140
AjK 5:8365c4cf8f33 141 1.5 - 21/11/2010
AjK 5:8365c4cf8f33 142
AjK 5:8365c4cf8f33 143 * Calling putc() (or any derived function that uses it like
AjK 5:8365c4cf8f33 144 printf()) while inside an interrupt service routine can
AjK 5:8365c4cf8f33 145 cause the system to lock up if the TX buffer is full. This
AjK 5:8365c4cf8f33 146 is because bytes are only transferred from the TX buffer to
AjK 5:8365c4cf8f33 147 the TX FIFO via the TX ISR. If we are, say in an RX ISR already,
AjK 5:8365c4cf8f33 148 then the TX ISR will never trigger. The TX buffer stays full and
AjK 5:8365c4cf8f33 149 there is never space to putc() the byte. So, while putc() blocks
AjK 5:8365c4cf8f33 150 waiting for space it calls isr_tx() to ensure if TX FIFO space
AjK 5:8365c4cf8f33 151 becomes available it will move bytes from the TX buffer to TX
AjK 5:8365c4cf8f33 152 FIFO thus removing the blocking condition within putc().
AjK 5:8365c4cf8f33 153
AjK 4:28de979b77cf 154 1.4 - 21/11/2010
AjK 4:28de979b77cf 155
AjK 4:28de979b77cf 156 * Removed all the new DMA code. I wish mbed.org had proper SVN
AjK 4:28de979b77cf 157 versioning, I'm use to working in HEAD and BRANCHES after I've
AjK 4:28de979b77cf 158 released a project. Getting bug reports in current releases
AjK 4:28de979b77cf 159 while trying to dev new code is hard to manage without source
AjK 4:28de979b77cf 160 control of some type!
AjK 4:28de979b77cf 161
AjK 2:b936b4acbd92 162 1.3 - 21/11/2010
AjK 2:b936b4acbd92 163
AjK 2:b936b4acbd92 164 * Fixed a macro problem with txIsBusy()
AjK 2:b936b4acbd92 165 * Started adding code to use "block data" sending using DMA
AjK 3:0f10f536456e 166 * Removed #include "IOMACROS.h"
AjK 1:b7e435fbfe8e 167
AjK 2:b936b4acbd92 168 1.2 - 21/11/2010
AjK 2:b936b4acbd92 169
AjK 2:b936b4acbd92 170 * Removed unsed variables from flushBuffer()
AjK 2:b936b4acbd92 171 * Fixed a bug where both RX AND TX fifos are cleared/reset
AjK 2:b936b4acbd92 172 when just TX OR RX should be cleared.
AjK 2:b936b4acbd92 173 * Fixed a bug that cleared IIR when in fact it should be left
AjK 2:b936b4acbd92 174 alone so that any pending interrupt after flush is handled.
AjK 2:b936b4acbd92 175 * Merged setBase() into init() as it wasn't required anywhere else.
AjK 2:b936b4acbd92 176 * Changed init() to enforce _uidx is set by Serial to define the _base
AjK 2:b936b4acbd92 177 address of the Uart in use.
AjK 2:b936b4acbd92 178
AjK 1:b7e435fbfe8e 179 1.1 - 20/11/2010
AjK 1:b7e435fbfe8e 180
AjK 1:b7e435fbfe8e 181 * Added this file
AjK 1:b7e435fbfe8e 182 * Removed cruft from GETC.cpp
AjK 1:b7e435fbfe8e 183 * "teh" should be "the", why do my fingers do that?
AjK 1:b7e435fbfe8e 184
AjK 1:b7e435fbfe8e 185 1.0 - 20/11/2010
AjK 1:b7e435fbfe8e 186
AjK 1:b7e435fbfe8e 187 * First release.
