SmartPort & Camera_Control

Pins Definition

  • S1: PB4   TIM3_CH1
  • S2: PB5   TIM3_CH2
  • S3: PB6   TIM4_CH1
  • S4: PB7   TIM4_CH1
  • S5: PB3   TIM2_CH2
  • S6: PB10  TIM2_CH3
  • Rssi pad: PA0  TIM5_CH1
  • 2812LED: PA8  TIM1_CH1

Enable SoftSerial_TX on S5 or S6 pad

1. Connect the inverted telemetry signal to S5 pad

2. Turn on “SOFTSERIAL” & “TELEMETRY” in Configuration tab

3. CLI commands as following

  • resource motor 5 none
  • resource serial_tx 11 B03
  • save

4. Choose SOFTSERIAL1 for Smartport in Ports tab.

Enable Camera control on RSSI pad

1. Connect “OSD” pin of camera to RSSI pad

2. CLI command as following

  • resource camera_control A00
  • save

3. Stick commands for controlling the camera

  • ENTER: Roll Center, Pitch Center, Throttle Center, Yaw Right
  • LEFT: Throttle Center, Yaw Left
  • RIGHT: Throttle Center, Yaw Right
  • UP: Throttle Center, Pitch Up
  • DOWN: Throttle Center, Pitch Down
  • Adjust Value: Pitch,Throttle & Yaw Center, Roll Left or Right
  • Enclosed brass grommets are used to converte M3 to M2.
  • Enclosed silicon grommets are necessary to avoid the vibration woes.
  • T2 can be used for Smartaudio VTX & Tramp VTX protocol.
  • T1 can’t work with Tramp VTX protocol
  • Non-inversion hacks must be required for Frsky Smartport on T2.
  • DSM2, DSMX, IBUS, SUMD signal can be connected to R1 or R2
  • PPM share UART2-RX(R2) pad
  • S5(PB3) & S6(PB10) can be resourced to Softserial for Smartport
  • Rssi pad, PA0 with TIM5_CH1, can be resourced to Softserial or Camera Control
  • No Blackbox
