Andrew Tridgell 580e7b8a4a HAL_AVR: switch back to 500kHz SPI for MPU6k until we understand the issues 
this is for new plane release. We need for analysis before we can
re-enable high speed SPI
 2013-10-28 16:55:22 +11:00
Randy Mackay 443023bbbf AP_HAL: add ignore_errors to I2C driver 2013-10-21 20:01:32 +09:00

Randy Mackay f2f61af125 HAL_AVR: scheduler interrupt 500hz for APM2 2013-10-13 11:03:13 +09:00
Andrew Tridgell 04836ea763 HAL_AVR: set initial bus speed on MPU6k to 500kHz, then change to 8MHz 
this should allow us to work even with older chips. See the MPU6000
product specification, which says max 20MHz for sensor and interrupt
regs, and max 1MHz for all other regs
 2013-10-13 11:03:06 +09:00
Andrew Tridgell 4dc2f4bd58 HAL_AVR: spi3 at 8mhz for mpu6k and ms5611 2013-10-13 11:03:02 +09:00
John Arne Birkeland f6038f36bf HAL_AVR: Improved AVRTimer micros() and millis()

- micros() now has proper 1 us resolution and less overhead
- millis() has less overhead
- removed unneeded/unwanted initializatin of timers in AVRTimer::init()
 2013-10-13 11:03:00 +09:00
Andrew Tridgell 5ba34b38c1 HAL_AVR: added specialised transfer functions for MPU6k and APM1 ADC

Andrew Tridgell 18581d0220 HAL_AVR: change order of CS pin init - fixes APM2 boot problem 
We now init the MPU6k CS pin before the MS5611 CS pin. This should not
matter at all, but it turns out that it solves the APM2 boot
problem. We should investigate why, as this may indicate an electrical
problem.
