    * All callbacks now use MODSERIAL_callback (rather than Mbed's FunctionPointer[1] type)





Digixx

0:83e415034198


    19

      to store and invoke it's callbacks. This allows MODSERIAL to pass a parameter





Digixx

0:83e415034198


    20

      to callbacks. The function prototype is now void func(MODSERIAL_IRQ_INFO *q).





Digixx

0:83e415034198


    21

    * Callbacks now pass a pointer to a MODSERIAL_IRQ_INFO class type.





Digixx

0:83e415034198


    22

      This class holds a pointer to the MODSERIAL object that invoked the callback





Digixx

0:83e415034198


    23

      thus freeing callbacks need to use the global variable of the original 





Digixx

0:83e415034198


    24

      MODSERIAL instance.





Digixx

0:83e415034198


    25

    * MODSERIAL_IRQ_INFO also declares public functions that are protected within MODSERIAL





Digixx

0:83e415034198


    26

      thus allowing certain functions to be restricted to callback context only.





Digixx

0:83e415034198


    27

    * New function MODSERIAL_IRQ_INFO::rxDiscardLastChar() allows an rxCallback function





Digixx

0:83e415034198


    28

      to remove the character that was just placed into the RX buffer.

Digixx

0:83e415034198


    54







Digixx

0:83e415034198


    55

    * Added new "autoDetectChar()" function. To use:-





Digixx

0:83e415034198


    56

      1st: Add a callback to invoke when the char is detected:-        





Digixx

0:83e415034198


    57

        .attach(&detectedChar, MODSERIAL::RxAutoDetect);





Digixx

0:83e415034198


    58

      2nd: Send the char to detect.





Digixx

0:83e415034198


    59

        .autoDectectChar('\n');





Digixx

0:83e415034198


    60

      Whenever that char goes into the RX buffer your callback will be invoked.





Digixx

0:83e415034198


    61

      Added example2.cpp to demo a simple messaging system using this auto feature.

0:83e415034198

    66

    * Fixed a minor issue with 1.10 missed an alteration of name change.

Digixx

0:83e415034198


    69







Digixx

0:83e415034198


    70

    * Rename the DMA callback from attach_dma_complete() to attach_dmaSendComplete()





Digixx

0:83e415034198


    71

    





Digixx

0:83e415034198

0:83e415034198


    73

0:83e415034198


    74

    * Added support for DMA sending of characters. Required is

Digixx

0:83e415034198


    80







Digixx

0:83e415034198


    81

    * Added code so that if a buffer is set to zero length then





Digixx

0:83e415034198


    82

      MODSERIAL defaults to just using the FIFO for that stream





Digixx

0:83e415034198


    83

      thus making the library "fall back" to teh same operation





Digixx

0:83e415034198


    84

      that the Mbed Serial library performs.





Digixx

0:83e415034198


    85

    * Removed dmaSend() function that should have been removed 





Digixx

0:83e415034198

0:83e415034198

Digixx

0:83e415034198


    90

    * Remove the DMA enum from MODSERIAL.h as it's not currently 





Digixx

0:83e415034198


    91

      ready for release.





Digixx

0:83e415034198


    92

    * Added page doxygen comments.

    96

   * Version 1.5 solved a blocking problem on putc() when called 





Digixx

0:83e415034198


    97

     from another ISR. However, isr_tx() invokes a callback of it's





Digixx

0:83e415034198


    98

     own when a byte is tranferred from TX buffer to TX FIFO. User





Digixx

0:83e415034198


    99

     programs may interpret that as an IRQ callback. That's an ISR





Digixx

0:83e415034198


   100

     call from within an existing ISR which is not good. So the 





Digixx

0:83e415034198


   101

     TxIrq callback from isr_tx is now conditional. It will only





Digixx

0:83e415034198


   102

     be called when isr_tx() is actually within it's own ISR and





Digixx

0:83e415034198


   103

     not when called from alternate ISR handlers.





Digixx

0:83e415034198

1.5 - 21/11/2010





Digixx

0:83e415034198


   106







Digixx

0:83e415034198


   107

    * Calling putc() (or any derived function that uses it like





Digixx

0:83e415034198


   108

      printf()) while inside an interrupt service routine can





Digixx

0:83e415034198


   109

      cause the system to lock up if the TX buffer is full. This





Digixx

0:83e415034198


   110

      is because bytes are only transferred from the TX buffer to





Digixx

0:83e415034198


   111

      the TX FIFO via the TX ISR. If we are, say in an RX ISR already,





Digixx

0:83e415034198


   112

      then the TX ISR will never trigger. The TX buffer stays full and





Digixx

0:83e415034198


   113

      there is never space to putc() the byte. So, while putc() blocks





Digixx

0:83e415034198


   114

      waiting for space it calls isr_tx() to ensure if TX FIFO space





Digixx

0:83e415034198


   115

      becomes available it will move bytes from the TX buffer to TX





Digixx

0:83e415034198


   116

      FIFO thus removing the blocking condition within putc().

Digixx

Digixx

0:83e415034198
