Multiwii 2.3
Acaba de salir la nueva version de la multiwii, la 2.3 (9 de noviembre)

Por si alguien esta pendiente de actualizar. Se puede descargar aqui:

Y la lista de cambio es esta:

***Control mode***

- main PITCH/ROLL/YAW PID modification (r1474)
- the sticks scaling is no more affected by PID coefficients
- yaw rate (to the right of the PIDs in GUI) now works as stick scaling
- default yaw rate is increased (with yaw rate at 0)
- yaw PID principle is now different from PITCH&ROLL PID:
- yaw ITerm windup is very high, allowing an 'elastic' direction return after a manual perturbation
- yaw ITerm is also constrained with a windup independent limit
- yaw PTerm is constrained in order to counter the yaw jump effect.
use yaw DTerm to increase this constrain (r1573)
- yaw ITerm is canceled if the yaw stick is not centered

- Throttle angle correction (r1374)

- Advanced Headfree mode added (see config.h for instructions) (r1374)

- DYNBALANCE option, individual motor can be controled via GUI, to test individual vibration

- better gyro & acc calibration accuracy (r1546)

- cannot arm is baro mode is on (r1550)

! baro mode should be activated only when the multi is nearly Z stable !
- only one baro mode : vario around a throttle deadband (r1554)

- magHold is reset when arm is switched on (r1553)

- ONLYARMWHENFLAT option (r1587)

***receiver & UART***

- RCSERIAL is now deeply integrated. If a MSP_SET_RAW_RC comes, it will just override legacy RX data. (r1420)
as a consequence, RCSERIAL is no more an option

- no RC averaging for Spektrum & SBUS (r1545)

- SBUS center define (r1568)



- Enables sonar altitude from i2c-gps-nav board (1424)

- navigation code will follow after 2.3


- Gui with Servosettings. (r1441 & r1450)
All models with servo included.

- GUI globalsettings (for some settings previously only in config.h)

- do not display /dev/cu.* devices but only corresponding /dev/tty.* (r1442)

- GUI baudrate as configurable setting


- lcd.telemtry: show max ground speed from gps data (r1398)

- lcd.telemetry: allow separate suppression of aux2 configuration (r1456)

- new display support 1.3" i2c OLED from (r1413)

- when abort, revert all values back to last saved state

- visual feedback from servos during midpoint trim via LCD

***IMU and baro***

- correct GYRO_SCALE for all gyro (r1428)

- no more small angles while shaking the board (r1579)

- baro Alt based on ground temp compensation (r1570)

- not I reset for FIWEDWING (r1590)

- add 6DOF LSM330 sensor (r1571)

- add ACC BMA280 sensor (r1600)

*** SERVO management ***

The pins for coptertypes with servos have been changed.
Attaching a servo to a motor pin can quickly destroy your servo.
All connection diagrams out there from v2.2 or older are no longer valid for v2.3 with servos using hardware PWM. ... figuration

- add 8 hardware PWM's for servos on MEGA boards. Servo outputs are 44,45,46,11,12,6,7,8 (r1384)

- Allow any servo refresh rate from 20 to 400Hz on Mega hardware PWM servos. (r1386)

- Tri servo moved to SERVO4 (pin11) on mega boards with HW PWM's. (r1392)

- a32u4 (nanoWii, MicroWii etc) HW PWM for 4 servos; warning different pins!!
(with lots of info and help from ronco)
(r1464 & r1470)

- add a generic way to configure servo settings : conf struct + MSP read/set messages (r1383)

- Added general servo handler (r1421 & r1429)

- allow preset of some servo stuff from config.h (r1432)

- Gui with Servosettings. (r1441)

- add gimbal servo stretcher usable with HW PWM's. (r1384)
We can get 180 degrees servo move without servo modification.
- note about gimbal: settings for neutral&endpoints are no more in config.h, but only in GUI

- do not update servos during unarmed calibration of sensors which are sensitive to vibration (r1408)

***internal improvements***

- migration to a cpp/h code structure (r1515 & r1516)

- huge flash size optimization (around 1k)
thanks to fine struct definitions + serialization over MSP (r1369)

- make powermeter computation time based (again) to reduce config hassle and increase accuracy (r1375)

- read at most one analog channel per MWii main loop cycle (r1375)

- smoothing of RX_RSSI (r1379)

- make faster analog reads an option with default off to increase accuracy (r1375)

- detangle vbat & buzzer dependancy (r1375)

- optimization : small approximation bit shift used instead of * or / number
for TPA, rates, dynP, dynD and expo curb (r1376)

- Added checking for flash content change, and reload config parameters in this case. (r1389)

- split Serial into Serial(core UART management) & Protocol (r1548)

- loop is globally faster


- option to suppress defaults in mwc sketch and load via gui from file instead (r1365)

- add OVERRIDE_PSENSORPIN option (r1375)

- manual for using Multiwii in Eclipse environment

- add amperage to MSP_ANALOG (r1542)


- no more than one MSP per port and per cycle
should smooth the delay while requesting MSP, especially for USB port on micro
gracias por la info, llevo meses dandole vueltas al PID, y no consigo acertar con la configuracion, ya parece que lo voy mejorando, a ver si con esta actualizacion con el cambio de la curva del trothle y con el mejor calibrado de los acelerometros, funciona un poco mas estable, gracias
This week the world will watch as nations gather in France for crunch climate talks. Known as COP21, or the 21st Conference of the Parties to the UN Framework Convention on Climate Change, a lot has been made of this year's meeting. But what exactly are the talks, and what are they trying to achieve? Find out more here
