Update the comment, to explain how to achive a different perescale
value.
Added PX4_IO_TIMER_ALTERNATE_RATE one board agnostic ifdef
PX4_IO_TIMER_ALTERNATE_RATE that is non board specific.
N.B. I would like to eliminate PX4_IO_TIMER_ALTERNATE_RATE
as well, but I need crazyflie HW to validate that the startup
script can just set the rate on the PWM to 3921 fast enough to
not effect the motors.
Working crazyflie firmware build
* Console on USART3
* Could not disable building PX4IO firmware, currently commented out
Don't build PX4IO firmware if the board doesn't ask for it
Added crazyflie motor driver
Fixed wrong register
CLK_SEL is in PWR_MGMT_1
Initial I2C/SPI MPU9250 device
* Tested with I2C
* Need to add error checking
* Intermittent crash on stop call
Working ak8963 mag driver
Functional lps25h driver. Work in progress.
Works well enough to probe and allow sensors task to start.
Added serial port test module
HACK! Get sensors module working
Set crazyflie PWM range
Extend baudrate for Crazyflie's NRF radio
Added dummy tone alarm to allow for init
Added autostart script for Crazyflie
