Andrew Tridgell 987cdaf3e1 DataFlash: make it safe to do DataFlash logging from timers
this uses a non-blocking semaphore take if we are in a timer
process. Useful for logging failsafe events

Andrew Tridgell c52ef80f06 DataFlash: added Block layer in classes
this will allow the addition of a DataFlash_File implementation of the
DataFlash API which will store logs in a traditional filesystem. That
will align better with the PX4 design, and be more useful for fast
transfer of logs to a host computer

Andrew Tridgell 28a0ba6c4a DataFlash: added block based dataflash writes
these are about 10x faster than the old writes

Pat Hickey a81de007d8 DataFlash: headers switch to use AP_HAL SPI device driver types 2012-12-20 14:51:36 +11:00
Pat Hickey cc699a2a4e DataFlash: conform to ordinary stdint types
* s/unsigned char/uint8_t/g
* changed all type 'byte' to uint8_t

rmackay9 785d9ca6a7 DataFlash_APM2: renamed semaphore to spi3_semaphore to make it more obvious which semaphore is required. 2012-10-18 17:00:05 +09:00
Pat Hickey 605f89fa69 DataFlash_APM2: private AP_Semaphore* rather than use extern AP_Semaphore_spi3
The AP_Semaphore* argument to the constructor can be null (and is by
default for compatibility). Semaphore is only used when non-null.

rmackay9 b9963f5b5c DataFlash: modified to use AP_Semaphore for SPI3 bus when required.
Also fixed test sketch which seemed broken.

rmackay9 2b24e422de DataFlash: revert delay callbacks to use "unsigned long" 2012-08-18 20:28:31 +09:00
rmackay9 20cb2e56a0 DataFlash: change "unsigned long" to "uint32_t" in callback functions 2012-08-18 19:22:14 +09:00
Andrew Tridgell dd24330645 DataFlash: fallback to BlockErase if ChipErase fails
The errata on the APM2 dataflash chip says that ChipErase may not work
on some chips

Andrew Tridgell fc73fd6531 DataFlash: use ChipErase() instead of PageErase() on all pages
This makes the DataFlash erase much faster (about 6 seconds instead of
about 60 seconds).

We need to test and ensure the behaviour is equivalent apart from the
speed

Andrew Tridgell 5e4f66e525 DataFlash: moved high level logging logic to library
this moves out all the high level logic from ArduPlane/ArduCopter to
the library. It also adds a "config page", as the last page in the
flash. This is used to check if the flash needs erasing. We only erase
now if the DF_LOGGING_FORMAT has changed.

This patch also adds a public CardInserted() method, which is used to
disable logging on APM2 if a dataflash card is not inserted

Andrew Tridgell 977326e991 dataflash: reworked classes to move most code to parent class
this moves all the non-hardware specific code to the parent
DataFlash_Class class, keeping the hw specific code much smaller and
simpler.

This should prevent discrepancies creeping in between APM1 and APM2
support again

Andrew Tridgell 13b2ddcbe1 dataflash: fixed APM2 flash logging
we had log wrap disabled on APM2, and also had the wrong log size. The
mainline code assumed 4096, but it is 8192 pages long.
