| AjK | 5:8365c4cf8f33 | 5 | * Calling putc() (or any derived function that uses it like |
| AjK | 5:8365c4cf8f33 | 6 | printf()) while inside an interrupt service routine can |
| AjK | 5:8365c4cf8f33 | 7 | cause the system to lock up if the TX buffer is full. This |
| AjK | 5:8365c4cf8f33 | 8 | is because bytes are only transferred from the TX buffer to |
| AjK | 5:8365c4cf8f33 | 9 | the TX FIFO via the TX ISR. If we are, say in an RX ISR already, |
| AjK | 5:8365c4cf8f33 | 10 | then the TX ISR will never trigger. The TX buffer stays full and |
| AjK | 5:8365c4cf8f33 | 11 | there is never space to putc() the byte. So, while putc() blocks |
| AjK | 5:8365c4cf8f33 | 12 | waiting for space it calls isr_tx() to ensure if TX FIFO space |
| AjK | 5:8365c4cf8f33 | 13 | becomes available it will move bytes from the TX buffer to TX |
| AjK | 5:8365c4cf8f33 | 14 | FIFO thus removing the blocking condition within putc(). |

| AjK | 4:28de979b77cf | 16 | 1.4 - 21/11/2010 |
| AjK | 4:28de979b77cf | 17 | |
| AjK | 4:28de979b77cf | 18 | * Removed all the new DMA code. I wish mbed.org had proper SVN |
| AjK | 4:28de979b77cf | 19 | versioning, I'm use to working in HEAD and BRANCHES after I've |
| AjK | 4:28de979b77cf | 20 | released a project. Getting bug reports in current releases |
| AjK | 4:28de979b77cf | 21 | while trying to dev new code is hard to manage without source |
| AjK | 4:28de979b77cf | 22 | control of some type! |

| AjK | 2:b936b4acbd92 | 24 | 1.3 - 21/11/2010 |
| AjK | 2:b936b4acbd92 | 25 | |
| AjK | 2:b936b4acbd92 | 26 | * Fixed a macro problem with txIsBusy() |
| AjK | 2:b936b4acbd92 | 27 | * Started adding code to use "block data" sending using DMA |
| AjK | 3:0f10f536456e | 28 | * Removed #include "IOMACROS.h" |
| AjK | 1:b7e435fbfe8e | 29 | |
| AjK | 2:b936b4acbd92 | 30 | 1.2 - 21/11/2010 |
| AjK | 2:b936b4acbd92 | 31 | |
| AjK | 2:b936b4acbd92 | 32 | * Removed unsed variables from flushBuffer() |
| AjK | 2:b936b4acbd92 | 33 | * Fixed a bug where both RX AND TX fifos are cleared/reset |
| AjK | 2:b936b4acbd92 | 34 | when just TX OR RX should be cleared. |
| AjK | 2:b936b4acbd92 | 35 | * Fixed a bug that cleared IIR when in fact it should be left |
| AjK | 2:b936b4acbd92 | 36 | alone so that any pending interrupt after flush is handled. |
| AjK | 2:b936b4acbd92 | 37 | * Merged setBase() into init() as it wasn't required anywhere else. |
| AjK | 2:b936b4acbd92 | 38 | * Changed init() to enforce _uidx is set by Serial to define the _base |
| AjK | 2:b936b4acbd92 | 39 | address of the Uart in use. |
| AjK | 2:b936b4acbd92 | 40 | |
| AjK | 1:b7e435fbfe8e | 41 | 1.1 - 20/11/2010 |

| AjK | 1:b7e435fbfe8e | 44 | * Removed cruft from GETC.cpp |
| AjK | 1:b7e435fbfe8e | 45 | * "teh" should be "the", why do my fingers do that? |
| AjK | 1:b7e435fbfe8e | 46 | |
| AjK | 1:b7e435fbfe8e | 47 | 1.0 - 20/11/2010 |
| AjK | 1:b7e435fbfe8e | 48 | |
