Jason Short a6b874b591 DataFlash : Removed Chip Erase - relying on Block erase only 2012-08-15 21:04:24 -07:00
Craig Elder 0534ac12b1 DataFlash: The current method for checking if chip erase worked is producing false positives. We are forcing the block erase until we have a deterministic test method. 2012-07-09 15:23:35 -07:00
Andrew Tridgell c6ff292721 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 c2fb8a7a98 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 089470a671 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 9f5718bcfa added in DataFlash.cpp 
forgot this ....

Pat Hickey afef359ee9 purple: rework DataFlash to separate purple and APM1 hardware support 
the purple support is still a work in progress, but the APM1 support
should be fine

Doug Weibel a11ea12ca8 Change to logging file system. 
This commit is somewhat temporary as I have come up with a better scheme and will be modifying this.  Just making this commit in case I need to roll back

Andrew Tridgell 5410dff523 DataFlash: use CPU independent data types 
this ensures that the DataFlash API is consistent for different CPU
architectures, which matters for the Desktop build, and will matter
for ARM and other CPUs later

rmackay9@yahoo.com b930b892c2 DataFlash library - changed to use standard arduino SPI library

rmackay9@yahoo.com 3b87530b74 DataFlash - backed out recent changes to make it use SPI while I figure out the cause of some people's compile errors

rmackay9@yahoo.com 3ef57bf3bf DataFlash - modified to use Arduino SPI interface instead of directly using registers. Also moved "dataflash_CS_inactive" calls to end of functions instead of beginning so that it doesn't monopolize the SPI bus.
