Trying to log data from UM6 sensor with GPS receiver LS20031. I have two problems: - I can't log to file at a fast rate (<0.5s) without data values freezing to a fixed value. Print to pc screen it works fine. Ideally I would do this with an interrupt (e.g. ticker) so that the time of each reading is a fixed interval - I removed this as I thought this was causing the problem. - I want to record GPS lat and long. I have setup the GPS ground speed so I know the sensor are communicating. So I possibly havent set the config file to correctly interpet these two signals.

lhiggs | 0:03c649c76388 | 21 | * Bug fix, not blocking on transmit |
lhiggs | 0:03c649c76388 | 22 | by Erik Petrich, http://mbed.org/forum/bugs-suggestions/topic/2200 |
lhiggs | 0:03c649c76388 | 23 | |
lhiggs | 0:03c649c76388 | 24 | 1.19 20 April 2011 |
lhiggs | 0:03c649c76388 | 25 | |
lhiggs | 0:03c649c76388 | 26 | * Fixed some doxygen comment bugs. |
lhiggs | 0:03c649c76388 | 27 | |
lhiggs | 0:03c649c76388 | 28 | 1.18 20 April 2011 |
lhiggs | 0:03c649c76388 | 29 | |
lhiggs | 0:03c649c76388 | 30 | * All callbacks now use MODSERIAL_callback (rather than Mbed's FunctionPointer[1] type) |
lhiggs | 0:03c649c76388 | 31 | to store and invoke it's callbacks. This allows MODSERIAL to pass a parameter |
lhiggs | 0:03c649c76388 | 32 | to callbacks. The function prototype is now void func(MODSERIAL_IRQ_INFO *q). |
lhiggs | 0:03c649c76388 | 33 | * Callbacks now pass a pointer to a MODSERIAL_IRQ_INFO class type. |
lhiggs | 0:03c649c76388 | 34 | This class holds a pointer to the MODSERIAL object that invoked the callback |
lhiggs | 0:03c649c76388 | 35 | thus freeing callbacks need to use the global variable of the original |
lhiggs | 0:03c649c76388 | 36 | MODSERIAL instance. |
lhiggs | 0:03c649c76388 | 37 | * MODSERIAL_IRQ_INFO also declares public functions that are protected within MODSERIAL |
lhiggs | 0:03c649c76388 | 38 | thus allowing certain functions to be restricted to callback context only. |
lhiggs | 0:03c649c76388 | 39 | * New function MODSERIAL_IRQ_INFO::rxDiscardLastChar() allows an rxCallback function |
lhiggs | 0:03c649c76388 | 40 | to remove the character that was just placed into the RX buffer. |

lhiggs | 0:03c649c76388 | 44 | 1.17 08/Mar/2011 |
lhiggs | 0:03c649c76388 | 45 | Fixed a memory leak in the DMA code. |
lhiggs | 0:03c649c76388 | 46 | |
lhiggs | 0:03c649c76388 | 47 | 1.16 - 12 Feb 2011 |
lhiggs | 0:03c649c76388 | 48 | |
lhiggs | 0:03c649c76388 | 49 | * Missed one, doh! |
lhiggs | 0:03c649c76388 | 50 | |
lhiggs | 0:03c649c76388 | 51 | 1.15 - 12 Feb 2011 |
lhiggs | 0:03c649c76388 | 52 | |
lhiggs | 0:03c649c76388 | 53 | * Fixed some typos. |
lhiggs | 0:03c649c76388 | 54 | |
lhiggs | 0:03c649c76388 | 55 | 1.14 - 7 Feb 2011 |
lhiggs | 0:03c649c76388 | 56 | |
lhiggs | 0:03c649c76388 | 57 | * Fixed a bug in __putc() that caused the output buffer pointer to |
lhiggs | 0:03c649c76388 | 58 | become corrupted. |
lhiggs | 0:03c649c76388 | 59 | |
lhiggs | 0:03c649c76388 | 60 | 1.13 - 20/01/2011 |
lhiggs | 0:03c649c76388 | 61 | |
lhiggs | 0:03c649c76388 | 62 | * Added extra documentation. |
lhiggs | 0:03c649c76388 | 63 | * Fixed some typos. |
lhiggs | 0:03c649c76388 | 64 | |
lhiggs | 0:03c649c76388 | 65 | 1.12 - 20/01/2011 |
lhiggs | 0:03c649c76388 | 66 | |
lhiggs | 0:03c649c76388 | 67 | * Added new "autoDetectChar()" function. To use:- |
lhiggs | 0:03c649c76388 | 68 | 1st: Add a callback to invoke when the char is detected:- |
lhiggs | 0:03c649c76388 | 69 | .attach(&detectedChar, MODSERIAL::RxAutoDetect); |
lhiggs | 0:03c649c76388 | 70 | 2nd: Send the char to detect. |
lhiggs | 0:03c649c76388 | 71 | .autoDectectChar('\n'); |
lhiggs | 0:03c649c76388 | 72 | Whenever that char goes into the RX buffer your callback will be invoked. |
lhiggs | 0:03c649c76388 | 73 | Added example2.cpp to demo a simple messaging system using this auto feature. |
lhiggs | 0:03c649c76388 | 74 | |
lhiggs | 0:03c649c76388 | 75 | |
lhiggs | 0:03c649c76388 | 76 | 1.11 - 23/11/2010 |
lhiggs | 0:03c649c76388 | 77 | |
lhiggs | 0:03c649c76388 | 78 | * Fixed a minor issue with 1.10 missed an alteration of name change. |
lhiggs | 0:03c649c76388 | 79 | |
lhiggs | 0:03c649c76388 | 80 | 1.10 - 23/11/2010 |
lhiggs | 0:03c649c76388 | 81 | |
lhiggs | 0:03c649c76388 | 82 | * Rename the DMA callback from attach_dma_complete() to attach_dmaSendComplete() |
lhiggs | 0:03c649c76388 | 83 | |
lhiggs | 0:03c649c76388 | 84 | 1.9 - 23/11/2010 |
lhiggs | 0:03c649c76388 | 85 | |
lhiggs | 0:03c649c76388 | 86 | * Added support for DMA sending of characters. Required is |
lhiggs | 0:03c649c76388 | 87 | the MODDMA library module:- |
lhiggs | 0:03c649c76388 | 88 | http://mbed.org/users/AjK/libraries/MODDMA/latest |
lhiggs | 0:03c649c76388 | 89 | See example_dma.cpp for more information. |
lhiggs | 0:03c649c76388 | 90 | |
lhiggs | 0:03c649c76388 | 91 | 1.8 - 22/11/2010 |
lhiggs | 0:03c649c76388 | 92 | |
lhiggs | 0:03c649c76388 | 93 | * Added code so that if a buffer is set to zero length then |
lhiggs | 0:03c649c76388 | 94 | MODSERIAL defaults to just using the FIFO for that stream |
lhiggs | 0:03c649c76388 | 95 | thus making the library "fall back" to teh same operation |
lhiggs | 0:03c649c76388 | 96 | that the Mbed Serial library performs. |
lhiggs | 0:03c649c76388 | 97 | * Removed dmaSend() function that should have been removed |
lhiggs | 0:03c649c76388 | 98 | at 1.7 |
lhiggs | 0:03c649c76388 | 99 | |
lhiggs | 0:03c649c76388 | 100 | 1.7 - 21/11/2010 |
lhiggs | 0:03c649c76388 | 101 | |
lhiggs | 0:03c649c76388 | 102 | * Remove the DMA enum from MODSERIAL.h as it's not currently |
lhiggs | 0:03c649c76388 | 103 | ready for release. |
lhiggs | 0:03c649c76388 | 104 | * Added page doxygen comments. |
lhiggs | 0:03c649c76388 | 105 | |
lhiggs | 0:03c649c76388 | 106 | 1.6 - 21/11/2010 |
lhiggs | 0:03c649c76388 | 107 | |
lhiggs | 0:03c649c76388 | 108 | * Version 1.5 solved a blocking problem on putc() when called |
lhiggs | 0:03c649c76388 | 109 | from another ISR. However, isr_tx() invokes a callback of it's |
lhiggs | 0:03c649c76388 | 110 | own when a byte is tranferred from TX buffer to TX FIFO. User |
lhiggs | 0:03c649c76388 | 111 | programs may interpret that as an IRQ callback. That's an ISR |
lhiggs | 0:03c649c76388 | 112 | call from within an existing ISR which is not good. So the |
lhiggs | 0:03c649c76388 | 113 | TxIrq callback from isr_tx is now conditional. It will only |
lhiggs | 0:03c649c76388 | 114 | be called when isr_tx() is actually within it's own ISR and |
lhiggs | 0:03c649c76388 | 115 | not when called from alternate ISR handlers. |
lhiggs | 0:03c649c76388 | 116 | |
lhiggs | 0:03c649c76388 | 117 | 1.5 - 21/11/2010 |
lhiggs | 0:03c649c76388 | 118 | |
lhiggs | 0:03c649c76388 | 119 | * Calling putc() (or any derived function that uses it like |
lhiggs | 0:03c649c76388 | 120 | printf()) while inside an interrupt service routine can |
lhiggs | 0:03c649c76388 | 121 | cause the system to lock up if the TX buffer is full. This |
lhiggs | 0:03c649c76388 | 122 | is because bytes are only transferred from the TX buffer to |
lhiggs | 0:03c649c76388 | 123 | the TX FIFO via the TX ISR. If we are, say in an RX ISR already, |
lhiggs | 0:03c649c76388 | 124 | then the TX ISR will never trigger. The TX buffer stays full and |
lhiggs | 0:03c649c76388 | 125 | there is never space to putc() the byte. So, while putc() blocks |
lhiggs | 0:03c649c76388 | 126 | waiting for space it calls isr_tx() to ensure if TX FIFO space |
lhiggs | 0:03c649c76388 | 127 | becomes available it will move bytes from the TX buffer to TX |
lhiggs | 0:03c649c76388 | 128 | FIFO thus removing the blocking condition within putc(). |
lhiggs | 0:03c649c76388 | 129 | |
lhiggs | 0:03c649c76388 | 130 | 1.4 - 21/11/2010 |
lhiggs | 0:03c649c76388 | 131 | |
lhiggs | 0:03c649c76388 | 132 | * Removed all the new DMA code. I wish mbed.org had proper SVN |
lhiggs | 0:03c649c76388 | 133 | versioning, I'm use to working in HEAD and BRANCHES after I've |
lhiggs | 0:03c649c76388 | 134 | released a project. Getting bug reports in current releases |
lhiggs | 0:03c649c76388 | 135 | while trying to dev new code is hard to manage without source |
lhiggs | 0:03c649c76388 | 136 | control of some type! |
lhiggs | 0:03c649c76388 | 137 | |
lhiggs | 0:03c649c76388 | 138 | 1.3 - 21/11/2010 |
lhiggs | 0:03c649c76388 | 139 | |
lhiggs | 0:03c649c76388 | 140 | * Fixed a macro problem with txIsBusy() |
lhiggs | 0:03c649c76388 | 141 | * Started adding code to use "block data" sending using DMA |
lhiggs | 0:03c649c76388 | 142 | * Removed #include "IOMACROS.h" |
lhiggs | 0:03c649c76388 | 143 | |
lhiggs | 0:03c649c76388 | 144 | 1.2 - 21/11/2010 |
lhiggs | 0:03c649c76388 | 145 | |
lhiggs | 0:03c649c76388 | 146 | * Removed unsed variables from flushBuffer() |
lhiggs | 0:03c649c76388 | 147 | * Fixed a bug where both RX AND TX fifos are cleared/reset |
lhiggs | 0:03c649c76388 | 148 | when just TX OR RX should be cleared. |
lhiggs | 0:03c649c76388 | 149 | * Fixed a bug that cleared IIR when in fact it should be left |
lhiggs | 0:03c649c76388 | 150 | alone so that any pending interrupt after flush is handled. |
lhiggs | 0:03c649c76388 | 151 | * Merged setBase() into init() as it wasn't required anywhere else. |
lhiggs | 0:03c649c76388 | 152 | * Changed init() to enforce _uidx is set by Serial to define the _base |
lhiggs | 0:03c649c76388 | 153 | address of the Uart in use. |
lhiggs | 0:03c649c76388 | 154 | |

lhiggs | 0:03c649c76388 | 157 | * Added this file |
lhiggs | 0:03c649c76388 | 158 | * Removed cruft from GETC.cpp |
lhiggs | 0:03c649c76388 | 159 | * "teh" should be "the", why do my fingers do that? |
lhiggs | 0:03c649c76388 | 160 | |
