Keil project not updated, I have no way to verify it.
Note, mw.c, drv_pwm.c and drv_system.c contain code for too many topics.
Later commits will relocate the code as appropriate.
Not even looked at utils yet. 'Utils' is a bad naming practice and is a
synonym for 'too lazy to find the right file/name'.
comments that duplicated code. Comments are harder to refactor than
code and become stale. Updating default and limit values for some
settings to use enum values.
PWM6+7/TIM3_CH3+4/PB0+PB1
Update software serial to monitor serial pins for signal changes instead
of periodically sampling pin signals.
When reading the data the timer used is syncronized to the falling edge
of the start bit which allows for better syncronisation at higher
speeds. The code has been tested OK from 1200 baud to 19200. 38400
baud was tested and partially usable but has been disabled because there
are too many transmit and receive errors, especially when transmitting
and receiving at the same time.
Due to the way a single timer is used for transmitting and receiving, if
data comes in while transmitting the system may incorrectly transmit a
short or long bit. However at 19200 and below this didn't cause a
problem in the limited testing I performed.
set motor_pwm_rate to some value > 500 (1000, 8000, 16000 etc works on my scope).
then the motor output can be used to directly drive brushed motor fets.
PWM is rescaled to 0-base in brushed mode, so all same values of min/maxthrottle apply.
If telemetry_switch=1 it change baudrate and protocol using aux channel, either it switch when armed/disarmed.
This allows to keep MSP serial while armed for BT dongle if needed.
see comments in code for things to fix. added new variable to cli, fixedwing_althold_dir (though its value isn't really clear, I think it should always be positive since servo direction mix is done later).
* Proper initialization sequence framework for various supported GPS types. NMEA will now auto-detect its baud rate based on received frames.
* As a result of the above, gps_baudrate has been changed to enum, to only allow fixed rates. (GPS baudrate, -1: autodetect (NMEA only), 0: 115200, 1: 57600, 2: 38400, 3: 19200, 4: 9600)
* UBX binary initialization at any specified baudrate with auto-reconnect on signal loss.
* GPS thread to handle initialization, signal loss and configuration. No longer does GPS need to be powered before FC, and on GPS reconnect, it will be re-initialized if needed.
MTK NMEA/binary initialization is omitted for now, as I can't find my MTK GPS
GPS deltaTime can be calculated to display update rate.

First cut at polymorphic serial port implementation. Split serialPort_t into uartPort_t and serialPort_t. Calls to uartWrite() can now be replaced with calls to serialWrite().
Replacing calls to serialWriteByte(softSerial_t*, char) with calls to serialWrite(serialPort_t*, char). This completes the proof of concept for polymorphic serial port implementations (uartPort and softSerialPort).
Renaming isSerialAvailable to uartTotalBytesWaiting. Renaming serialAvailable to softSerialTotalBytesWaiting. Adding serialTotalBytesWaiting to serial API and updating calls to the former methods to use the serial API.
Renaming serialRead to softSerialRead. Adding serialRead to serial API and updating calls to uartRead and softSerialRead to use the serial API. Renamed uartPrint to serialPrint which now works on any serialPort implementation.
Replacing calls to isUartTransmitEmpty with isSoftSerialTransmitBufferEmpty. Replacing remaing calls to uartWrite with serialWrite. Adding isSoftSerialTransmitBufferEmpty to the serial API. Adding serialSet/GetBaudRate to the serial API. Since softSerial does not implement serialSetBaudRate some GPS serial initialisation code has been updated.
At this point it is probably possible to switch around all the ports and use a software serial implementation if desired.

FEATURE_SPEKTRUM has been removed and replaced with FEATURE_SERIALRX.
cli option serialrx_type now configures what type of receiver it is
0 = spektrum1024, 1 = spektrum2048, 2 = sbus
sbus will need hardware inverter to use.
also cleaned up receiver drivers to assign readrawRC callback instead of assigning in code in main()
none of this has been tested.

tri_unarmed_servo to 1 (default) always updates tri servo whether armed or not.
tri_unarmed_servo to 0 will only send servo signal to tail servo when armed.
