px4dev	bc35bb23dd	HOTFIX: disable interrupt-driven I2C mode, configure pessimistic I2C timeout, correct handling of the NAK generation for I2C master reads. ... This looks like it addresses the recent I2C lockup issue, unfortunately it also increases CPU consumption by ~5% for the I2C sensor bus.	2013-01-18 00:43:57 -08:00
Lorenz Meier	c3c76ef3d5	Hardened the EEPROM attach routine for param storage	2012-10-29 09:44:59 +01:00
px4dev	2fc1032069	Major formatting/whitespace cleanup	2012-10-23 23:51:13 -07:00
px4dev	1e59a592a6	Split the parameter load/save commands out of the 'eeprom' command, since that's not really the obvious place for them. Add parameter printing functionality (though, it's a mess due to %f being busted) ... Update the script examples to use the new command.	2012-10-09 22:45:36 -07:00
Lorenz Meier	47c96d3d12	Quite flyable state	2012-09-12 18:50:24 +02:00
px4dev	a9c4fabda6	Change the EEPROM read/write timeout behavior so that we can get actual errors rather than just hanging forever.	2012-09-09 11:14:54 -07:00
px4dev	65ecf1b1c1	Rework the 'eeprom erase' path so it's possible to erase an EEPROM that can't be mounted. ... Add some bus reset code to the EEPROM read path to maybe help with bus lockup.	2012-09-09 00:04:43 -07:00
px4dev	1a781c6c4a	Make the distinction between "parameter import" which merges parameters, and "parameter load" which blows away any current changes.	2012-08-28 22:15:25 -07:00
px4dev	e6f6a81d5b	Allow the EEPROM driver to consider itself started even if NXFFS fails to mount.	2012-08-27 19:42:40 -07:00
Lorenz Meier	8eeba595ee	Improved param load / store text feedback, ported sensors app to new driver model, ready for merge and test	2012-08-25 19:16:12 +02:00
Lorenz Meier	d12c09cc86	improvements / debugging on I2C drivers	2012-08-24 14:58:14 +02:00
Lorenz Meier	45e178eaa3	Made error message more verbose	2012-08-24 11:50:01 +02:00
px4dev	0472eeae05	Add EEPROM read/write performance counters.	2012-08-23 23:15:55 -07:00
px4dev	5ef6a41012	Add a modified version of the stock AT24xx EEPROM driver tweaked for our uses. ... Use I2C_TRANSFER to avoid racing with other devices on the bus. Clock at 400kHz.	2012-08-23 23:04:26 -07:00
