* drivers, magnetometer: added ak09916 driver to support the mag driver emulated by the Here2 gps
* boards: set yaw 270 rotation for external ak09916 driver and only start it for the PH21
* drivers: only start ak09916 when icm20948 is not available on a ph21 setup
* Support for armv7-m_dcache control via parameter
The FORCE_F7_DCACHE parameter can be set to
0 - (default) if Eratta exits turn dcache off else leave it on
1 - Force it off
2 - Force it on
At boot the system will disable the d-cache if the silicon
has the 1259864 Data corruption in a sequence of Write-Through
stores and loads eratta.
Post nsh script execution the FORCE_F7_DCACHE paramater
will be used to set the d-cache to the state indicated
above.
With a DLPF of 62.5 Hz, the sampling rate is apperently not 1 kHz anymore,
because the driver got duplicate samples and published only at 128 Hz.
We have to increase the filter back to 500 Hz so that we get 1 kHz sampling
rate, with 250 Hz publications.
- Accel: use cutoff of 62.5 Hz instead of 500 Hz
- Gyro: the cutoff frequency is coupled with the ODR and is fixed to 116 Hz
at 1 kHz readout rate. So this patch does not change anything for the
gyro.
Because BATT_SMBUS is using a different structure (the ModuleBase class), and `BATT_SMBUS::task_spawn` is only called for the `start` command. This is the reason why you don't need to check for it in here.
using only <px4_getopt.h> as include, cleanup related includes
added check that all the option are valid (myoptind >= argc). if there are invalid options on some script that might now lead not to run commands
Rate changes were doing an asynchronous register reload via the EGR_UG. This could extend a PWM pulse up to 2X.
This fix removes the asynchronous update. The net effect is the the rate change will occur on the next counter expiration. The worst case is the rate change is delayed by 20 Ms.
