Re: New Multiwii Serial Protocol
I need a change to MSProtocol in order to support 6S HV lipos. Todays HV lipo cells support 4.35V, soon to come 4.55V. For 6S, this equals 27.3V. At the moment, we use uint8_t for storage, which is no longer sufficient. Affected structs are typedef struct { uint8_t vbat; // battery voltage in 0.1V s...

Re: recover the roll and pitch values
the standard MultiWii gui (your screenshot) only polls values every so often - you would miss most values in a series.
Probably must write your own polling code and somehow check if you are fast enough to get all values of the series.

In general, do not move around pin assignments unless you know your way around.
328p with MWii would allow for more than 3motors+1servo outputs, I think.
Try and find how additional gimbal servos are supported.

The following would be true for original MWii ( for 32bit derivatives I do not know):
MWii does know current voltage and allows to define 3 alarm levels already. (also the nominal voltage aka resting voltage when charged can be defined)
I do not understand what it is you had to implement

with 328p you only have one serial - also used for usb. So you cannot have both at the same time. While it was possible to run GPS on 328p in the past, it is not recommended - and I have no idea if/how it fits in the small memory. My advice is to get your GPS gadget working with a MEGA board first (...

when sensor as 6050 are positioned 'hanging on the wall' then you will get very different ranges in the raw data from the sensor already. Your best bet is to re-tune your PIDs.

yes, but
at one point we decided to have all features off by default. So users are forced to go through config.h in any case. As Alex put it "MWii is not a product".
With some TX/RX combos it is easier to begin with when failsafe is off.

please check your voltage dividers. If sum of both resistors is too high (whatever that value may be) then the arduino input seems to float and provide phantasy values for analogRead(). One symptom is if arduino value changes drastically once you attach a voltmeter in parallel to the arduino input.

The huge copter body works as a giant dampener against all movements of pit h roll and throttle change. If too extreme you might have to use beefier power system
If you are lucky then a high P value for roll and pitch should do the magic.
