AHRS: Merged in some new code from Dschin that expliclity writes the prediction terms in the covariance matrix. Also made changes to compile with -Os. Now runs around 125 - 150 Hz depending on corrections used (this will become adjustable from GCS shortly). Squashed commit of the following: commit 897e3365ab6c762584c34238efd12dc144e72af0 Author: James Cotton <peabody124@gmail.com> Date: Mon Sep 13 22:15:21 2010 -0500 AHRS: Getting it running nice and quickly. commit 53d72fb849164730c89873cab81c9e09be0b112b Author: James Cotton <peabody124@gmail.com> Date: Mon Sep 13 15:57:46 2010 -0500 AHRS: Make more variables volatile for -Os. commit 4fa90821b5d3d8c2ea5e67756313a8a63c0eeb8c Author: James Cotton <peabody124@gmail.com> Date: Mon Sep 13 15:11:31 2010 -0500 AHRS/Makefile: -O0 not added to allow me to try various space flags that don't break code. commit 5bd17a304dc28dc271c2f3e8c6cb8ad4a830404f Author: James Cotton <peabody124@gmail.com> Date: Mon Sep 13 14:44:05 2010 -0500 AHRS: Make debuggign USART easy to disable commit 5453f2a7939492769fe9e9cc822e69c107320670 Author: James Cotton <peabody124@gmail.com> Date: Mon Sep 13 14:38:37 2010 -0500 AHRS: Explicitly expand covariance prediction. Brings computations from 160 to 90. Makes it not fit in AHRS though. commit b6712da7eece2a464a2073d24b77be22bfa47094 Author: James Cotton <peabody124@gmail.com> Date: Sun Sep 12 22:59:42 2010 -0500 AHRS: Make it easy to comment out the I2C/Magnetometers. commit 8c84d0091f3d6f6bedc7a0224a4ed9cb099b022b Author: James Cotton <peabody124@gmail.com> Date: Thu Sep 9 00:49:50 2010 -0500 AHRS: Small change to INSGPS analysis tools git-svn-id: svn://svn.openpilot.org/OpenPilot/trunk@1613 ebee16cc-31ac-478f-84a7-5cbb03baadba

i2c: rewrite i2c layer The STM32 I2C block has a number of errata associated with it. These errata are primarily related to timing sensitivities between the peripheral and the interrupt handler. In particular, the correct generation of the stop bit relies on the I2C IRQ running immediately and not being held off for any reason. NOTE: The I2C interrupts must be the highest priority IRQs in the system to ensure correct operation. I2C protocol is now implemented as a formal state machine. See: stm32_i2c_fsm.{dot,jpg} for FSM description. I2C init is now expressed by const initializers in pios_board.c for both OP and AHRS boards. I2C device drivers (ie. bmp085/hmc5843) now pass in const arrays of an unlimited number of bus transfers to be done atomically. The I2C adapter driver now handles all bus-level locking across the list of transactions. Generation of start/restart/stop conditions are handled automatically over the list of transactions. Timeouts have been removed from the API for now. May be added back later. This driver has run error free on both the OP and AHRS boards for up to 48hrs but it still sometimes fails earlier than that on the OP board. There is another possible set of improvements to the driver that could employ the DMA engine for transfers of >= 2bytes. This change would reduce the timing sensitivities between the peripheral and the driver but unfortunately, both the SPI and I2C interfaces share the DMA1 engine. That means only one of these two peripherals can use the DMA engine and right now, SPI between OP and AHRS is already using it. Failures are currently fatal and will lock up the CPU. This allows useful information to be obtained in the failure cases. git-svn-id: svn://svn.openpilot.org/OpenPilot/trunk@1241 ebee16cc-31ac-478f-84a7-5cbb03baadba
