Randy Mackay f5488bc447 HAL: MPU6k and Baro SPI to 8Mhz 2013-11-15 21:58:32 +09:00
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

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

Andrew Tridgell 4dc2f4bd58 HAL_AVR: spi3 at 8mhz for mpu6k and ms5611 2013-10-13 11:03:02 +09:00
tobias 4e7fea787b HAL_AVR: corrected includes to replace #include "$HEADER" with #inlcude "utility/$HEADER"
adding -I for EVERY DIRECTORY isn't desirable

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.
