AjK | 20:59c74aaedda2 | 10 | by Erik Petrich, http://mbed.org/forum/bugs-suggestions/topic/2200 |
AjK | 20:59c74aaedda2 | 11 | |
AjK | 20:59c74aaedda2 | 12 | 1.19 20 April 2011 |
AjK | 20:59c74aaedda2 | 13 | |
AjK | 20:59c74aaedda2 | 14 | * Fixed some doxygen comment bugs. |
AjK | 20:59c74aaedda2 | 15 | |
AjK | 18:21ef26402365 | 16 | 1.18 20 April 2011 |
AjK | 18:21ef26402365 | 17 | |
AjK | 18:21ef26402365 | 18 | * All callbacks now use MODSERIAL_callback (rather than Mbed's FunctionPointer[1] type) |
AjK | 18:21ef26402365 | 19 | to store and invoke it's callbacks. This allows MODSERIAL to pass a parameter |
AjK | 18:21ef26402365 | 20 | to callbacks. The function prototype is now void func(MODSERIAL_IRQ_INFO *q). |
AjK | 18:21ef26402365 | 21 | * Callbacks now pass a pointer to a MODSERIAL_IRQ_INFO class type. |
AjK | 18:21ef26402365 | 22 | This class holds a pointer to the MODSERIAL object that invoked the callback |
AjK | 18:21ef26402365 | 23 | thus freeing callbacks need to use the global variable of the original |
AjK | 18:21ef26402365 | 24 | MODSERIAL instance. |
AjK | 18:21ef26402365 | 25 | * MODSERIAL_IRQ_INFO also declares public functions that are protected within MODSERIAL |
AjK | 18:21ef26402365 | 26 | thus allowing certain functions to be restricted to callback context only. |
AjK | 18:21ef26402365 | 27 | * New function MODSERIAL_IRQ_INFO::rxDiscardLastChar() allows an rxCallback function |
AjK | 18:21ef26402365 | 28 | to remove the character that was just placed into the RX buffer. |

AjK | 17:6c9b57c14868 | 32 | 1.17 08/Mar/2011 |
AjK | 17:6c9b57c14868 | 33 | Fixed a memory leak in the DMA code. |
AjK | 17:6c9b57c14868 | 34 | |
AjK | 16:8b1dbf4cce4e | 35 | 1.16 - 12 Feb 2011 |
AjK | 16:8b1dbf4cce4e | 36 | |
AjK | 16:8b1dbf4cce4e | 37 | * Missed one, doh! |
AjK | 16:8b1dbf4cce4e | 38 | |
AjK | 15:a1d9e745d71e | 39 | 1.15 - 12 Feb 2011 |
AjK | 15:a1d9e745d71e | 40 | |
AjK | 15:a1d9e745d71e | 41 | * Fixed some typos. |
AjK | 15:a1d9e745d71e | 42 | |
AjK | 14:3c3b87617bfe | 43 | 1.14 - 7 Feb 2011 |
AjK | 14:3c3b87617bfe | 44 | |
AjK | 14:3c3b87617bfe | 45 | * Fixed a bug in __putc() that caused the output buffer pointer to |
AjK | 14:3c3b87617bfe | 46 | become corrupted. |
AjK | 14:3c3b87617bfe | 47 | |
AjK | 13:70bb7c1769fa | 48 | 1.13 - 20/01/2011 |
AjK | 13:70bb7c1769fa | 49 | |
AjK | 13:70bb7c1769fa | 50 | * Added extra documentation. |
AjK | 13:70bb7c1769fa | 51 | * Fixed some typos. |
AjK | 13:70bb7c1769fa | 52 | |
AjK | 12:8c7394e2ae7f | 53 | 1.12 - 20/01/2011 |
AjK | 12:8c7394e2ae7f | 54 | |
AjK | 12:8c7394e2ae7f | 55 | * Added new "autoDetectChar()" function. To use:- |
AjK | 12:8c7394e2ae7f | 56 | 1st: Add a callback to invoke when the char is detected:- |
AjK | 12:8c7394e2ae7f | 57 | .attach(&detectedChar, MODSERIAL::RxAutoDetect); |
AjK | 12:8c7394e2ae7f | 58 | 2nd: Send the char to detect. |
AjK | 12:8c7394e2ae7f | 59 | .autoDectectChar('\n'); |
AjK | 12:8c7394e2ae7f | 60 | Whenever that char goes into the RX buffer your callback will be invoked. |
AjK | 12:8c7394e2ae7f | 61 | Added example2.cpp to demo a simple messaging system using this auto feature. |
AjK | 12:8c7394e2ae7f | 62 | |
AjK | 12:8c7394e2ae7f | 63 | |
AjK | 11:a93a62eeeb9d | 64 | 1.11 - 23/11/2010 |
AjK | 11:a93a62eeeb9d | 65 | |
AjK | 11:a93a62eeeb9d | 66 | * Fixed a minor issue with 1.10 missed an alteration of name change. |
AjK | 11:a93a62eeeb9d | 67 | |
AjK | 10:725fe81aa9ff | 68 | 1.10 - 23/11/2010 |
AjK | 10:725fe81aa9ff | 69 | |
AjK | 18:21ef26402365 | 70 | * Rename the DMA callback from attach_dma_complete() to attach_dmaSendComplete() |
AjK | 10:725fe81aa9ff | 71 | |
AjK | 9:b3cdae80e7a9 | 72 | 1.9 - 23/11/2010 |
AjK | 9:b3cdae80e7a9 | 73 | |
AjK | 9:b3cdae80e7a9 | 74 | * Added support for DMA sending of characters. Required is |
AjK | 9:b3cdae80e7a9 | 75 | the MODDMA library module:- |
AjK | 9:b3cdae80e7a9 | 76 | http://mbed.org/users/AjK/libraries/MODDMA/latest |
AjK | 9:b3cdae80e7a9 | 77 | See example_dma.cpp for more information. |
AjK | 9:b3cdae80e7a9 | 78 | |
AjK | 8:775f860e94d3 | 79 | 1.8 - 22/11/2010 |
AjK | 8:775f860e94d3 | 80 | |
AjK | 8:775f860e94d3 | 81 | * Added code so that if a buffer is set to zero length then |
AjK | 8:775f860e94d3 | 82 | MODSERIAL defaults to just using the FIFO for that stream |
AjK | 8:775f860e94d3 | 83 | thus making the library "fall back" to teh same operation |
AjK | 8:775f860e94d3 | 84 | that the Mbed Serial library performs. |
AjK | 8:775f860e94d3 | 85 | * Removed dmaSend() function that should have been removed |
AjK | 8:775f860e94d3 | 86 | at 1.7 |
AjK | 8:775f860e94d3 | 87 | |
AjK | 7:ffa4a7cb7f8d | 88 | 1.7 - 21/11/2010 |
AjK | 7:ffa4a7cb7f8d | 89 | |
AjK | 7:ffa4a7cb7f8d | 90 | * Remove the DMA enum from MODSERIAL.h as it's not currently |
AjK | 7:ffa4a7cb7f8d | 91 | ready for release. |
AjK | 7:ffa4a7cb7f8d | 92 | * Added page doxygen comments. |
AjK | 7:ffa4a7cb7f8d | 93 | |
AjK | 6:c8f77fe1cc10 | 94 | 1.6 - 21/11/2010 |
AjK | 6:c8f77fe1cc10 | 95 | |
AjK | 6:c8f77fe1cc10 | 96 | * Version 1.5 solved a blocking problem on putc() when called |
AjK | 6:c8f77fe1cc10 | 97 | from another ISR. However, isr_tx() invokes a callback of it's |
AjK | 6:c8f77fe1cc10 | 98 | own when a byte is tranferred from TX buffer to TX FIFO. User |
AjK | 6:c8f77fe1cc10 | 99 | programs may interpret that as an IRQ callback. That's an ISR |
AjK | 6:c8f77fe1cc10 | 100 | call from within an existing ISR which is not good. So the |
AjK | 6:c8f77fe1cc10 | 101 | TxIrq callback from isr_tx is now conditional. It will only |
AjK | 6:c8f77fe1cc10 | 102 | be called when isr_tx() is actually within it's own ISR and |
AjK | 6:c8f77fe1cc10 | 103 | not when called from alternate ISR handlers. |
AjK | 6:c8f77fe1cc10 | 104 | |
AjK | 5:8365c4cf8f33 | 105 | 1.5 - 21/11/2010 |
AjK | 5:8365c4cf8f33 | 106 | |
AjK | 5:8365c4cf8f33 | 107 | * Calling putc() (or any derived function that uses it like |
AjK | 5:8365c4cf8f33 | 108 | printf()) while inside an interrupt service routine can |
AjK | 5:8365c4cf8f33 | 109 | cause the system to lock up if the TX buffer is full. This |
AjK | 5:8365c4cf8f33 | 110 | is because bytes are only transferred from the TX buffer to |
AjK | 5:8365c4cf8f33 | 111 | the TX FIFO via the TX ISR. If we are, say in an RX ISR already, |
AjK | 5:8365c4cf8f33 | 112 | then the TX ISR will never trigger. The TX buffer stays full and |
AjK | 5:8365c4cf8f33 | 113 | there is never space to putc() the byte. So, while putc() blocks |
AjK | 5:8365c4cf8f33 | 114 | waiting for space it calls isr_tx() to ensure if TX FIFO space |
AjK | 5:8365c4cf8f33 | 115 | becomes available it will move bytes from the TX buffer to TX |
AjK | 5:8365c4cf8f33 | 116 | FIFO thus removing the blocking condition within putc(). |
AjK | 5:8365c4cf8f33 | 117 | |
AjK | 4:28de979b77cf | 118 | 1.4 - 21/11/2010 |
AjK | 4:28de979b77cf | 119 | |
AjK | 4:28de979b77cf | 120 | * Removed all the new DMA code. I wish mbed.org had proper SVN |
AjK | 4:28de979b77cf | 121 | versioning, I'm use to working in HEAD and BRANCHES after I've |
AjK | 4:28de979b77cf | 122 | released a project. Getting bug reports in current releases |
AjK | 4:28de979b77cf | 123 | while trying to dev new code is hard to manage without source |
AjK | 4:28de979b77cf | 124 | control of some type! |
AjK | 4:28de979b77cf | 125 | |
AjK | 2:b936b4acbd92 | 126 | 1.3 - 21/11/2010 |
AjK | 2:b936b4acbd92 | 127 | |
AjK | 2:b936b4acbd92 | 128 | * Fixed a macro problem with txIsBusy() |
AjK | 2:b936b4acbd92 | 129 | * Started adding code to use "block data" sending using DMA |
AjK | 3:0f10f536456e | 130 | * Removed #include "IOMACROS.h" |
AjK | 1:b7e435fbfe8e | 131 | |
AjK | 2:b936b4acbd92 | 132 | 1.2 - 21/11/2010 |
AjK | 2:b936b4acbd92 | 133 | |
AjK | 2:b936b4acbd92 | 134 | * Removed unsed variables from flushBuffer() |
AjK | 2:b936b4acbd92 | 135 | * Fixed a bug where both RX AND TX fifos are cleared/reset |
AjK | 2:b936b4acbd92 | 136 | when just TX OR RX should be cleared. |
AjK | 2:b936b4acbd92 | 137 | * Fixed a bug that cleared IIR when in fact it should be left |
AjK | 2:b936b4acbd92 | 138 | alone so that any pending interrupt after flush is handled. |
AjK | 2:b936b4acbd92 | 139 | * Merged setBase() into init() as it wasn't required anywhere else. |
AjK | 2:b936b4acbd92 | 140 | * Changed init() to enforce _uidx is set by Serial to define the _base |
AjK | 2:b936b4acbd92 | 141 | address of the Uart in use. |
AjK | 2:b936b4acbd92 | 142 | |
AjK | 1:b7e435fbfe8e | 143 | 1.1 - 20/11/2010 |
AjK | 1:b7e435fbfe8e | 144 | |
AjK | 1:b7e435fbfe8e | 145 | * Added this file |
AjK | 1:b7e435fbfe8e | 146 | * Removed cruft from GETC.cpp |
AjK | 1:b7e435fbfe8e | 147 | * "teh" should be "the", why do my fingers do that? |
AjK | 1:b7e435fbfe8e | 148 | |
AjK | 1:b7e435fbfe8e | 149 | 1.0 - 20/11/2010 |
AjK | 1:b7e435fbfe8e | 150 | |
AjK | 1:b7e435fbfe8e | 151 | * First release. |
