AjK 13:70bb7c1769fa 5 * Added extra documentation.
AjK 13:70bb7c1769fa 6 * Fixed some typos.

AjK 12:8c7394e2ae7f 9
AjK 12:8c7394e2ae7f 10 * Added new "autoDetectChar()" function. To use:-
AjK 12:8c7394e2ae7f 11 1st: Add a callback to invoke when the char is detected:-
AjK 12:8c7394e2ae7f 12 .attach(&detectedChar, MODSERIAL::RxAutoDetect);
AjK 12:8c7394e2ae7f 13 2nd: Send the char to detect.
AjK 12:8c7394e2ae7f 14 .autoDectectChar('\n');
AjK 12:8c7394e2ae7f 15 Whenever that char goes into the RX buffer your callback will be invoked.
AjK 12:8c7394e2ae7f 16 Added example2.cpp to demo a simple messaging system using this auto feature.

AjK 11:a93a62eeeb9d 20
AjK 11:a93a62eeeb9d 21 * Fixed a minor issue with 1.10 missed an alteration of name change.

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