Short summary of changes. For a complete list see the git log.
2011-12-10
Merged a change that sorts the UAVO fields based on size. Because this changes
all of the objects, erase all existing flash files based on this.
2011-11-04
New Spektrum/JR satellite receiver driver implementation.
It now provides explicit selection of DSM2 (and DSMJ), DSMX (10bit) and
DSMX (11bit) serial protocol variations to better serve different frame
and resolution modes. The protocol name used now is DSM instead of
previously used Spektrum to make it less ambiguous when used with JR
2.4GHz radios.
2011-10-20
Inputs can be remapped to outputs to allow up to 10 channels of control. The
receiver inputs remap as follows:
Receiver 3 because output channel 7
Receiver 4 because output channel 8
Receiver 5 because output channel 9
Receiver 6 because output channel 10
2011-10-11
Fix for the Mac telemetry rates and specifically how long enumeration took.
2011-10-08
Make the flash chip need to be have bad magic for a full second before erasing
settings. Should avoid random lost settings.
2011-09-12
Max rate now ONLY applies to attitude and axis lock mode. Manual rate is the
only term that limits the rate mode now (and in axis lock when you push stick
only manual rate applies). Also integrals are reset when unused.
2011-09-09
Some large updates to the input system. Now multiple receivers can be
connected at once. A wizard was added for configuring the input channels. A
specific collective pitch channel was added.
2011-09-04
Improvements to the failsafe handling code for inputs. PWM power off is now
detected properly. Powering on transmitter for Spektrum Satellite no longer
causes a glitch on servos.
2011-08-10
Added Camera Stabilization and a gui to configure this. This is a software
selectable module from the GUI. However, a restart is required to make it
active. The GUI does not currently expose the configuration for using the
transmitter to change the view angle but this is supported by the hardware.
2011-08-10
By default a lot of diagnostic objects that were enabled by default are now
disabled in the build. This include TaskInfo (and all the FreeRTOS options
that provide that debugging information). Also MixerStatus, I2CStatus,
WatchdogStatus and RateDesired. These can be reenabled for debugging with
-DDIAGNOSTICS.
2011-08-04
Fixed packaging aesthetic issues. Also avoid runtime issues on OSX Lion by
disabling the ModelView and Notify plugins for now (sorry).

/*
* Currently known DSMx (DSM2, DSMJ, DSMX) satellite serial port settings:
* 115200bps serial stream, 8 bits, no parity, 1 stop bit
* size of each frame: 16 bytes
* data resolution: 10 or 11 bits
* number of frames: 1 or 2
* frame period: 11ms or 22ms
*
* Currently known DSMx frame structure:
* 2 bytes - depend on protocol version:
* for DSM2/DSMJ:
* 1 byte - lost frame counter (8 bit)
* 1 byte - data format (for master receiver bound with 3 or 5 pulses),
* or unknown (for slave receiver bound with 4 or 6 pulses,
* some sources call it also the lost frame counter)
* for DSMX:
* 1 byte - unknown data (does not look like lost frame counter)
* 1 byte - unknown data, has been seen only 0xB2 so far
* 14 bytes - up to 7 channels (16 bit word per channel) with encoded channel
* number, channel value, the "2nd frame in a sequence" flag.
* Unused channels have FF FF instead of data bytes.
*
* Data format identification:
* - for DSM2/DSMJ: [0 0 0 R 0 0 N1 N0]
* where
* R is data resolution (0 - 10 bits, 1 - 11 bits),
* N1..N0 is the number of frames required to receive all channel
* data (01 or 10 are known to the moment, which means 1 or 2 frames).
* Three values for the transmitter information byte have been seen
* thus far: 0x01, 0x02, 0x12.
* - for DSMX this byte contains just 0xB2 or 0xA2 value for any resolution.
* It is not known at the moment how to find the exact resolution from the
* DSMX data stream. The frame number (1 or 2) and 10/11 bit resolution were
* found in different data streams. So it is safer at the moment to ask user
* explicitly choose the resolution.
* Also some weird throttle channel (0) behavior was found in some streams
* from DX8 transmitter (all zeroes). Thus DSMX needs special processing.
*
* Channel data are:
* - for 10 bit: [F 0 C3 C2 C1 C0 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0]
* - for 11 bit: [F C3 C2 C1 C0 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0]
* where
* F is normally 0 but set to 1 for the first channel of the 2nd frame,
* C3 to C0 is the channel number, 4 bit, zero-based, in any order,
* Dx..D0 - channel data (10 or 11 bits)
*
* DSM2 protocol bug: in some cases in 2-frame format some bytes of the
* frame can contain invalid values from the previous frame. They usually
* are the last 5 bytes and can be equal to FF or other data from last
* frame. There is no explicit workaround currently known.
*
* Binding: the number of pulses within bind window after power up defines
* if this receiver is a master (provides receiver capabilities info to
* the transmitter to choose data format) or slave (does not respond to
* the transmitter which falls back to the old DSM mode in that case).
* Currently known are 3(4) pulses for low resolution (10 bit) DSM2 mode,
* 5(6) pulses for high resolution (11 bit) DSM2 mode, and also 7(8) and
* 9(10) pulses for DSMX modes. Thus only 3, 5, 7 or 9 pulses should be
* used for stand-alone satellite receiver to be bound correctly as the
* master.
