CC Hardware Configuration

In this page

When the CC3D flight controller is plugged into the GCS, the Hardware Configuration screen displays the ports available on the controller to allow them to be set according to use. The board can be mounted in any configuration on the airframe, and the orientation relative to the airframe configured such that the flight controller knows which way it is facing.

Ports

CopterControl, CC3D and Atom have 4 ports.

Open

• Servo Output 1-6: These are the PWM outputs that go to servos or ESCs. Power is typically applied through these headers from only one of the ESCs. The positive (Vcc) and negative (Gnd) pins are indicated on this diagram and the board.

  Servo output pin layout isOutside –> groundMiddle –> 5V - 15VInside –> signal

• MainPort: JST-SH 4-pin. This is a serial USART whose baud rate can be adjusted through the GCS. Optionally Futaba S.Bus receiver, Spektrum/JR satellite receiver or GPS can be mapped to the MainPort. Default configuration is Telemetry for connecting an RF modem.

• FlexiPort: JST-SH 4-pin. The function of this port also depends on the configuration and can be configured for I2C or Serial. The default configuration doesn’t use this port but it can be used for Telemetry, GPS, Spektrum satellite receivers (all working), and other I2C peripherals (under development).

• ReceiverPort : JST-SH 8-pin. The receiver port can act as an input or output port depending on the configuration which is set in the Hardware Settings. Configuring the receiver port as an output port allows the user to assign more output channels then the 6 standard servo outputs.

  ReceiverPort use depends on the type of RC receiver in use, and whether OneShot125 or PWMSync output is desired:

  • PWM

    • PWM+NoOneShot should be used with a normal PWM type receiver. The 6 rightmost wires of the receiver port carry the signal for each channel individually.
      
      

  • PPM - Pin 3 (For a Multirotor, please use the PPM_PIN8+OneShot described bellow, this allow PWMSync and OneShot)

    • PPM+NoOneShot is used with modern PPM type receivers, that combine the control signal to one wire.
      The PPM stream should be sent to the first input through the white wire connected to CC ReceiverPort wire/pin 3.
      For a PPM receiver, only one pin is used for signal - the remaining wires connected to CC ReceiverPort wires 4-8 are left unused.

    • PPM+PWM+NoOneShot combines the two modes above, wire/pin 3 is used for PPM and the rest, wires/pins 4-8 are used as PWM inputs.

    • PPM+Outputs+NoOneShot enables PPM input in ReceiverPort wire/pin 3, and PWM output in wires/pins 5-8. These work as output channels 7-10.
      
      

  • PPM - Pin 8

    • PPM_PIN8+OneShot is a prefered input mode, where PPM input wire is moved from previous ReceiverPort pin 3 to pin 8 to allow PWMSync and OneShot125 to be used as ESC output modes.
      See PWM, PWMSync, Oneshot Output page for more details.
      
      

  • RECEIVER PORT AS OUTPUTS

    • Outputs+OneShot makes ReceiverPort pins 5-8 work as output channels 7-10. ReceiverPort pins 3 and 4 are unused. This and the Disabled option can be used if the control communication is via a spektrum satellite receiver or directly through telemetry.
      
      

  • DISABLING

    • Disabled+OneShot basically disables the ReceiverPort.
      
      

  Default settings

  By default for a Multirotor, the Vehicle Setup Wizard will set receiver port as PPM_PIN8+OneShot when PPM type receiver is selected.
