Thank you very much for your reply.
After this failure occurred, I have reduced the number of equipment to a minimum during the testing phase.
1. CC3D hardware
Atom
2. Software
16.09+_r782-g8c101ad
3.operating system
Win10 LTSC 1809
CopterControl Virtual COM Port(COM5)
Driver date 2014/11/21
ver: 3.0.0.0
4. Equipment
Battery, 3S 2200ma
ESC, 2-3s, 40A, BEC 3A@5V
Receiver, Futaba R314SB
Remote control, 7px
Servo: emax ES08AII Analog servo
Connection protocol, S.bus2
5. Vehicle
Fixed Wing, Airframe type Vtail
Mixer Rudder is 100
6, Input
Transmitter type: Surface, mode 1 (this is a redundant choice)
Arming Settings ,Always Disarmed, timeout is 0.
I think YAW will not be subject to this restriction.
7, Save
I made sure that after I clicked the save button, a green check mark was displayed.
8. Failure phenomenon
After the normal setting, the direction control is normal.
The auto-stabilization function of the flight control is normal, and the rudder can be adjusted automatically according to the attitude.
Disconnect the battery, disconnect the USB cable, and reconnect the battery.
CC3D restarts, the green light is always on, and the blue light flashes once per second.
When using the remote control to turn the direction, the rudder does not respond.
Reconnect the usb cable and use the remote control configuration wizard to reconfigure.
When the remote control rotates the direction, the rudder servo is controlled normally.
Disconnect the battery again, disconnect the USB cable, and reconnect the battery.
CC3D restarts, the green light is always on, and the blue light flashes once per second
When using the remote control to turn the direction, the rudder does not respond.
8. Tests I have done
1) Replace the analog steering gear with digital steering gear, reconfigure the steering gear type, and the failure phenomenon is the same.
2) Replace the receiver with R3004SB, the remote control is 18sz, and run the remote control wizard again, the fault phenomenon is the same.
3) Using the Win7 operating system in the virtual machine, the software is the same, and the failure symptoms are the same.
4) Replace the ESC. After the voltage of the receiver is increased from 5V to 6V, the fault phenomenon is the same.
5) I replaced a new CC3D hardware with the same settings and the same failure symptoms.
6) The new and old CC3D, update firmware or update and delete the firmware, the symptoms are the same.
9. Other phenomena
After configuring Vehicle Setup Wizard and Transmitter Setup Wizard in turn, the rudder control is normal.
SYSTEM HEALTH'INPUT' is green
Switch to Vehicle, do not modify any settings, click the save button,
SYSTEM HEALTH'INPUT' is RED
The remote control cannot control the rudder.
The auto-stabilization function of the flight control can normally control the rotation of the steering gear.
During this period, I have generated a log file OP-2021-12-26_09-46-31.opl
It is in binary format and I cannot view the contents of the file.
10. RC Input: Critical
1) 0ne or more of the r/c input channel types is not set.
reply:
Throttle, type S.bus, Chan 2
Yaw, type S.bus, Chan 1
FlightMode,type S.bus, Chan 3
Accessory0 ,type S.bus, Chan 4
Other functions type is none, Number is Disabled.
This fault does not always exist. The same software settings and the same hardware have worked normally for at least one year.
This failure phenomenon only appeared in the past two months.
0n the GCS configwration page, make sure all inputs have a Type set.
reply:
Determine all the input channels that need to be used, and set the type.
See attached screenshot
0ne or more of the r/c input channel mappings are invalid.
reply:
Confirm that the selected channel is correct.
The driver is uninitialired for one or more of the r/c input channels.
reply:
The related settings work normally before the CC3D is powered off. Then there will be no problems with the driver.
Current flight mode is undefined: this indicates a bug in the code.
reply:
Flight mode, the default is Pos 2, which corresponds to Stabilized2, Setting Bank is Bank1.
Assisted Control is none.
Current flight mode set to guidance but flight status flight mode is reported as something other than alti tude hold.
reply:
I didn't use this, I don't know how to answer this question accurately.
During update of desired stabiliration mode, flight status is reported as something other than stabilired 1, 2, 3, 4, 5 or 6
reply:
I don't know how to reply to this question
I just need the stability of YAW
