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 | 12:8c7394e2ae7f | 33 | |
AjK | 12:8c7394e2ae7f | 34 | |
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 | 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 | |
