Add power subsystem.
Add PWR_VOLT_PIN, PWR_VOLT_SCALE, PWR_VOLT_LPF_A parameters.
Support BATTERY_STATUS mavlink messages streaming.
Add pw cli command.
Add voltage field to pyflix library.
pyflix@0.12.
SF_RC_LOSS_TIME - time without rc to activate failsafe.
SD_DESCEND_TIME - total time to decrease the throttle to zero.
Make controlTime nan on the start to simplify the logic.
MAV_SYS_ID - mavlink system id.
MAV_RATE_SLOW - rate of slow telemetry (e. g. heartbeats).
MAV_RATE_FAST - rate of fast telemetry (e. g. attitude, imu data).
The variable pointer is stored as a union field.
If `.integer` field is true, then integer pointer should be used.
Interfaces to parameters (cli and mavlink) keep working using floats.
Setting a non-finite value to int parameter will cause an error.
`.value` field is renamed to `.cache`.
Arm and disarm with gestures only: left stick right/down for arming, left/down for disarming.
Remove arming switch as it complicates arming gestures logic.
Remove MAV_CTRL_SCALE parameter as it complicates arming gestures logic, advise to decrease TILT_MAX when controlling with a smartphone.
Put some minimal thrust to motors to indicate armed state.
Rename build article to usage article, add flight instructions.
Implement channels mapping calibration.
Store mapping in parameters.
Get rid of `controls` array and store control inputs in `controlRoll`, `controlPitch`, ... variables.
Move `channels` variable to rc.ino, channels are not involved when controled using mavlink.
'Neutral' values are renamed to 'zero' - more precise naming.
`controlsTime` is renamed to `controlTime`.
Use unsigned values for channels.
Make channel values in simulation more alike to real world: unsigned values in range [1000, 2000].
Send RC_CHANNELS_RAW instead of RC_CHANNELS_SCALED via mavlink
Don't send channels data via mavlink if rc is not used
* Unified parameters storage.
* Store parameters in flash on the hardware.
* Store parameters in text file in simulation.
* Work with parameters in command line.
* Support parameters in MAVLink for working with parameters in QGC.
