Andrew Tridgell 1e2214f8d1 DataFlash: fix for HAL_GPIO_* 2014-06-02 10:42:36 +10:00
Andrew Tridgell e6bafa2d8f DataFlash: added structures to Init() of dataflash
this will allow the get_log_data() call to add FMT headers if a log
has wrapped

Andrew Tridgell 97b7130bb9 libraries: update license header to GPLv3
we switched to GPLv3 a long time ago, but neglected to update the
per-file license headers

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 20825cc903 DataFlash: removed the byte and word based interfaces
simplifing ready for PX4 flash logging
2013-03-01 07:18:25 +11:00
Andrew Tridgell f3005c4267 DataFlash: use bulk SPI transfer() method
this reduces the per-byte overhead of flash logging to about 3.9 usec
2013-01-13 17:31:42 +11:00
Andrew Tridgell 28a0ba6c4a DataFlash: added block based dataflash writes
these are about 10x faster than the old writes

Pat Hickey 390e96311e DataFlash: change to new style Semaphore library 2013-01-03 13:48:07 -08:00

Pat Hickey cc699a2a4e DataFlash: conform to ordinary stdint types
* s/unsigned char/uint8_t/g
* changed all type 'byte' to uint8_t

Andrew Tridgell 17c115d2aa SITL: don't define __AVR_ATmega2560__ on desktop build
this allows us to properly separate the desktop build in the code

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.
2012-10-09 11:38:52 -07:00
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

Jason Short ce2a608706 Dataflash Logs : Fixed block erase on APM2
Byte order for 512 vs 528 was reversed.

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
2012-07-04 12:42:46 +10:00
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

rmackay9 c45b124cbe DataFlash_APM2 - moved CS_inactive call (which disables the dataflash) from the beginning to the end of all methods. This means the dataflash does not monopolize the SPI bus.
Also formatting changes to use tab instead of space. Sorry, should have done this as a separate check-in to the above changes.
2012-04-21 20:14:45 +09:00
Randy Mackay ed19c25a97 Arduino 1.0 - changed all #includes of "WProgram.h", "wiring.h" and "WConstants.h to "Arduino.h".
Modified FastSerial's write function to return size_t (number of bytes written).

Andrew Tridgell 880c7e6411 DataFlash: cope with older dataflash chips
some of the APM2 DataFlash cards use an older chip with only 4096
pages, and a density code of 6. Doug has one of these.

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 bd9488f1e4 DataFlash: fixed sense of card detect 2011-12-28 16:00:48 +11:00
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.
