OSD Menu for CCD FPV Cameras

From Banggood Forums:
Bang Good CCD camera SKU224879 OSD Menu Setup

NOTE: Many Bang Good CCD cameras have built in OSD (On Screen Menus) that enable users to set many powerful parameters on the cameras, but these OSD menus require a separately purchased OSD board (SKU239628), and the menus can be very difficult to navigate if your native language is not Chinese, since menus are initially provided in Chinese characters!

This blog provides English translations of the OSD menu for one CCD camera (SKU224879) and instructs how to set the menu language to the owner's native tongue.

To save your settings and especially the OSD menu in your own language, scroll down to the 7th menu item (Camera Set), press your MENU or Enter button to go to the Camera Set menu, scroll down again to the 5th option (Language), and press the R=Right or L=Left button to select your language. Then scroll down to the last (RET) option, click the Enter button, and scroll down to the last (9th) option (EXIT) and click the Enter button again to save your changes to the board. Now the next time you power up the board, this language and the other new settings will be used.

Hope you find this helpful. -VirginiaJim

Buzzer Solutions for CC3D, CleanFlight, SBUS

Basically there are 2 methods for buzzer control: Connecting to receiver outputs or connecting to flight controller. First method provides only basic functionality like control by a switch or activation by loss of radio connection. Second method provides additional functionality like signaling on arm/disarm, low voltage, flight modes, etc.

This is a list of different methods gathered from several forum posts. I've only verified method 4 working.

1 - Connect Buzzer to Receiver Servo Output
On CPPM mode, receiver channel outputs 7 & 8 are for PWM servo output.
- Connect this buzzer between a servo output channel and a servo like an extension wire.
http://www.myrcmart.com/rc-lost-model-alarm-findertracker-for-planegliderhelicopter-p-3145.html
- When there is no stick movement for 1 minute on Ele or Ail sticks, buzzer starts beeping

2 - Solder buzzer to CC3D STM32 pin
- Solder the circuit below to pin 15 of STM32 chip on CC3D board



- Setup buzzer configuration in CleanFlight configurator

3 - Use a Buzzer Enabled BetaFlight deployment
Possible BetaFlight versions: 2.1.6
Download: https://github.com/borisbstyle/betaflight/releases/tag/v2.1.6
- With this version, connect buzzer to Pin6 of CC3D output channels (motor output pins). See diagram below.
- Setup buzzer configuration in CleanFlight configurator

Active buzzer alarm modules already includes the transistor circuit above. In this case connect buzzer signal pin to motor output 6 signal pin. Connect +5v and gnd pins to a +5v source on the board. You can use any free channel output as +5v source also.


4 - Enable Buzzer on BetaFlight CLI
Possible in BetaFlight versions after 2.1.6
Hardware Notes:
- I can confirm that Discovery Buzzer from HobbyKing works: http://www.hobbyking.com/hobbyking/store/__14521__HobbyKing_174_Discovery_Buzzer.html
- I could not manage to make this active buzzer working with this method:
http://www.ebay.com/itm/221686970259

Setup:
- Connect buzzer to Pin6 of CC3D output channels (motor output pins) . See diagram above.
- CLI Command: set enable_buzzer_p6 = ON
- Setup buzzer configuration in CleanFlight configurator
     - Add Beeper mode in Modes tab. Assign an AUX switch as set in transmitter configuration.
     - Use CLI command beeper to adjust CC3D control.
            beeper -all disables all options
            beeper all enables all options
            Specific options:
# beeper
 beeper GYRO_CALIBRATED
 beeper RX_LOST
 beeper RX_LOST_LANDING
 beeper DISARMING
 beeper ARMING
 beeper ARMING_GPS_FIX
 beeper BAT_CRIT_LOW
 beeper BAT_LOW
 beeper GPS_STATUS
 beeper RX_SET                 ;enable buzzer control through a transmitter switch
 beeper ACC_CALIBRATION
 beeper ACC_CALIBRATION_FAIL
 beeper READY_BEEP
 beeper MULTI_BEEPS
 beeper DISARM_REPEAT
 beeper ARMED
 beeper SYSTEM_INIT
 beeper ON_USB
This is the configuration I'm using:
beeper -ALL
beeper RX_LOST
beeper ARMED
beeper BAT_LOW
beeper RX_SET
save



5 - Move SBUS channels on Receiver
For Frsky PWM receivers like X4R-SB.
This method connects buzzer to the receiver. CC3D buzzer setup is not used.
Note: X4R-SB firmware must be updated to CPPM version from:
- Bind receiver to enable SBUS and 10 channel setup. This mode can be set by connecting group 2 and group 3 pins with a jumper while powering the receiver
- On Taranis, create an input switch to control buzzer and assign to channel 9 
- Connect buzzer cable to group 2 pins (+, - and signal) on receiver
- Check that there are enough AUX channels allowed in BetaFlight (v2.4.1 RC2 and newer). CLI command to set number of AUX channels is:
    set max_aux_channels = xx
- On CleanFlight configurator, check that AUX9 is controlled by the buzzer switch assigned on Taranis. CC3D must be on Serial / SBUS mode.

6 - Move AUX channels on CC3D
This method connects buzzer to the receiver. CC3D buzzer setup is not used.
- Connect buzzer cable to group 1,2 or 3 pins (+, - and signal) on receiver
- On Taranis, create an input switch to control buzzer and assign to Channel corresponding to the group pins selected (Channel 1,2 or 3)
- Check that there are enough AUX channels allowed in BetaFlight (v2.4.1 RC2 and newer). CLI command to set number of AUX channels is:
    set max_aux_channels = xx
- On CleanFlight configurator, change receiver channel setup from TAER1234 to 1234TAER. This will free channels 1-4 for AUX switches. Issue the following command on CLI tab:
           remap 1234TAER
- On CleanFlight configurator, check that corresponding AUX channel is controlled by the buzzer switch assigned on Taranis. CC3D must be on Serial / SBUS mode.
