Falcon2 V1.2.1


Version History

Coming Soon – Version 1.4.1

  • Up to 25% increase in processor loop time performance, (by offloading sensor communications to the microcontroller’s Direct Memory Access Controller (DMA))
  • Faster battery monitoring code
  • Support for 50Hz, 400Hz and 490Hz PWM, OneShot125, OneShot42, Multishot, DShot150 and DShot300 ESC protocols
  • Added timing compatibility with BLHeli_32 ESCs
  • Support with auto-detect for HMC5883L, HMC5983, QMC5883L (both A and B versions), as well as LIS3MDL external magnetometers
  • Battery cell detection and voltage drop compensation in automated modes
  • Addition of Falcon 1 style gyroscope and accelerometer SAFE screen option
  • Disable ARM/DISARM transmitter switch above the minimum throttle threshold, this is to prevent inadvertently disarming the aircraft during flight
  • Note: Firmware versions V1.2.0 to V1.2.1 will seamlessly update, retaining your previous settings. Versions below and special builds above this will require a factory reset, in this instance your previous settings will be lost.

Version 1.2.1

  • SBUS automatic re-sychronisation
  • Inserted MPU-9250 gyro/accelerometer/magnetometer initialisation delay

Version 1.2.0

  • Transmitter YAW stick or ARM switch options
  • Idle Up Mode (aka Motor Stop)
  • Air Mode
  • FrSky X4R-SB receiver CPPM and SBUS – SBUS requires external +3.3V inverter circuit
  • FrSky SPort telemetry – requires external TX, RX inverter circuit
  • OSD with external Minim and Micro Minim OSD boards – uses Falcon OSD firmware, requires external I2C level shifter circuit
  • Improved throttle handover when switching to automated modes (Alt. Hold, Loiter or RTL)
  • Failsafe Modes – NONE, LAND and RTL

Version 1.1.1

  • Improved OLED display update rate using Direct Memory Access Controller (DMA) transfer

Version 1.1.0

  • Added “ESC Output” option to Misc Settings menu, in order to silence some ESCs in SAFE and MENU modes
  • Reversed edge triggering on CPPM receivers for FrSky compatibility

Version 1.0.1

  • Fixed driver output on M3 and M4 in Oneshot125 mode

Version 1.0.0

  • Original Version
