AjK 14:3c3b87617bfe 3 1.14 - 7 Feb 2011
AjK 14:3c3b87617bfe 4
AjK 14:3c3b87617bfe 5 * Fixed a bug in __putc() that caused the output buffer pointer to
AjK 14:3c3b87617bfe 6 become corrupted.
AjK 14:3c3b87617bfe 7
AjK 13:70bb7c1769fa 8 1.13 - 20/01/2011
AjK 13:70bb7c1769fa 9
AjK 13:70bb7c1769fa 10 * Added extra documentation.
AjK 13:70bb7c1769fa 11 * Fixed some typos.
AjK 13:70bb7c1769fa 12
AjK 12:8c7394e2ae7f 13 1.12 - 20/01/2011
AjK 12:8c7394e2ae7f 14
AjK 12:8c7394e2ae7f 15 * Added new "autoDetectChar()" function. To use:-
AjK 12:8c7394e2ae7f 16 1st: Add a callback to invoke when the char is detected:-
AjK 12:8c7394e2ae7f 17 .attach(&detectedChar, MODSERIAL::RxAutoDetect);
AjK 12:8c7394e2ae7f 18 2nd: Send the char to detect.
AjK 12:8c7394e2ae7f 19 .autoDectectChar('\n');
AjK 12:8c7394e2ae7f 20 Whenever that char goes into the RX buffer your callback will be invoked.
AjK 12:8c7394e2ae7f 21 Added example2.cpp to demo a simple messaging system using this auto feature.

AjK 12:8c7394e2ae7f 23
AjK 11:a93a62eeeb9d 24 1.11 - 23/11/2010
AjK 11:a93a62eeeb9d 25
AjK 11:a93a62eeeb9d 26 * Fixed a minor issue with 1.10 missed an alteration of name change.
AjK 11:a93a62eeeb9d 27
AjK 10:725fe81aa9ff 28 1.10 - 23/11/2010
AjK 10:725fe81aa9ff 29
AjK 10:725fe81aa9ff 30 * Reanme the DMA callback from attach_dma_complete() to attach_dmaSendComplete()
AjK 10:725fe81aa9ff 31
AjK 9:b3cdae80e7a9 32 1.9 - 23/11/2010
AjK 9:b3cdae80e7a9 33
AjK 9:b3cdae80e7a9 34 * Added support for DMA sending of characters. Required is
AjK 9:b3cdae80e7a9 35 the MODDMA library module:-
AjK 9:b3cdae80e7a9 36 http://mbed.org/users/AjK/libraries/MODDMA/latest
AjK 9:b3cdae80e7a9 37 See example_dma.cpp for more information.
AjK 9:b3cdae80e7a9 38
AjK 8:775f860e94d3 39 1.8 - 22/11/2010
AjK 8:775f860e94d3 40
AjK 8:775f860e94d3 41 * Added code so that if a buffer is set to zero length then
AjK 8:775f860e94d3 42 MODSERIAL defaults to just using the FIFO for that stream
AjK 8:775f860e94d3 43 thus making the library "fall back" to teh same operation
AjK 8:775f860e94d3 44 that the Mbed Serial library performs.
AjK 8:775f860e94d3 45 * Removed dmaSend() function that should have been removed
AjK 8:775f860e94d3 46 at 1.7
AjK 8:775f860e94d3 47
AjK 7:ffa4a7cb7f8d 48 1.7 - 21/11/2010
AjK 7:ffa4a7cb7f8d 49
AjK 7:ffa4a7cb7f8d 50 * Remove the DMA enum from MODSERIAL.h as it's not currently
AjK 7:ffa4a7cb7f8d 51 ready for release.
AjK 7:ffa4a7cb7f8d 52 * Added page doxygen comments.
AjK 7:ffa4a7cb7f8d 53
AjK 6:c8f77fe1cc10 54 1.6 - 21/11/2010
AjK 6:c8f77fe1cc10 55
AjK 6:c8f77fe1cc10 56 * Version 1.5 solved a blocking problem on putc() when called
AjK 6:c8f77fe1cc10 57 from another ISR. However, isr_tx() invokes a callback of it's
AjK 6:c8f77fe1cc10 58 own when a byte is tranferred from TX buffer to TX FIFO. User
AjK 6:c8f77fe1cc10 59 programs may interpret that as an IRQ callback. That's an ISR
AjK 6:c8f77fe1cc10 60 call from within an existing ISR which is not good. So the
AjK 6:c8f77fe1cc10 61 TxIrq callback from isr_tx is now conditional. It will only
AjK 6:c8f77fe1cc10 62 be called when isr_tx() is actually within it's own ISR and
AjK 6:c8f77fe1cc10 63 not when called from alternate ISR handlers.
AjK 6:c8f77fe1cc10 64
AjK 5:8365c4cf8f33 65 1.5 - 21/11/2010
AjK 5:8365c4cf8f33 66
AjK 5:8365c4cf8f33 67 * Calling putc() (or any derived function that uses it like
AjK 5:8365c4cf8f33 68 printf()) while inside an interrupt service routine can
AjK 5:8365c4cf8f33 69 cause the system to lock up if the TX buffer is full. This
AjK 5:8365c4cf8f33 70 is because bytes are only transferred from the TX buffer to
AjK 5:8365c4cf8f33 71 the TX FIFO via the TX ISR. If we are, say in an RX ISR already,
AjK 5:8365c4cf8f33 72 then the TX ISR will never trigger. The TX buffer stays full and
AjK 5:8365c4cf8f33 73 there is never space to putc() the byte. So, while putc() blocks
AjK 5:8365c4cf8f33 74 waiting for space it calls isr_tx() to ensure if TX FIFO space
AjK 5:8365c4cf8f33 75 becomes available it will move bytes from the TX buffer to TX
AjK 5:8365c4cf8f33 76 FIFO thus removing the blocking condition within putc().
AjK 5:8365c4cf8f33 77
AjK 4:28de979b77cf 78 1.4 - 21/11/2010
AjK 4:28de979b77cf 79
AjK 4:28de979b77cf 80 * Removed all the new DMA code. I wish mbed.org had proper SVN
AjK 4:28de979b77cf 81 versioning, I'm use to working in HEAD and BRANCHES after I've
AjK 4:28de979b77cf 82 released a project. Getting bug reports in current releases
AjK 4:28de979b77cf 83 while trying to dev new code is hard to manage without source
AjK 4:28de979b77cf 84 control of some type!
AjK 4:28de979b77cf 85
AjK 2:b936b4acbd92 86 1.3 - 21/11/2010
AjK 2:b936b4acbd92 87
AjK 2:b936b4acbd92 88 * Fixed a macro problem with txIsBusy()
AjK 2:b936b4acbd92 89 * Started adding code to use "block data" sending using DMA
AjK 3:0f10f536456e 90 * Removed #include "IOMACROS.h"
AjK 1:b7e435fbfe8e 91
AjK 2:b936b4acbd92 92 1.2 - 21/11/2010
AjK 2:b936b4acbd92 93
AjK 2:b936b4acbd92 94 * Removed unsed variables from flushBuffer()
AjK 2:b936b4acbd92 95 * Fixed a bug where both RX AND TX fifos are cleared/reset
AjK 2:b936b4acbd92 96 when just TX OR RX should be cleared.
AjK 2:b936b4acbd92 97 * Fixed a bug that cleared IIR when in fact it should be left
AjK 2:b936b4acbd92 98 alone so that any pending interrupt after flush is handled.
AjK 2:b936b4acbd92 99 * Merged setBase() into init() as it wasn't required anywhere else.
AjK 2:b936b4acbd92 100 * Changed init() to enforce _uidx is set by Serial to define the _base
AjK 2:b936b4acbd92 101 address of the Uart in use.
AjK 2:b936b4acbd92 102
AjK 1:b7e435fbfe8e 103 1.1 - 20/11/2010
AjK 1:b7e435fbfe8e 104
AjK 1:b7e435fbfe8e 105 * Added this file
AjK 1:b7e435fbfe8e 106 * Removed cruft from GETC.cpp
AjK 1:b7e435fbfe8e 107 * "teh" should be "the", why do my fingers do that?
AjK 1:b7e435fbfe8e 108
AjK 1:b7e435fbfe8e 109 1.0 - 20/11/2010
AjK 1:b7e435fbfe8e 110
AjK 1:b7e435fbfe8e 111 * First release.
