Firmware upgrade 2.42b6 – AUTOTUNE Support 

GUI (Windows, OS X, Linux): SimpleBGC_GUI_2_42b6.zip 

User Manual (English): SimpleBGC_32bit_manual_2_42_eng.pdf 

  • 4xPWM servo output with adjustable rate to output virtual channels decoded from RC input, or driven by Serial API
  • PID auto-tuning
  • Adaptive PID gains
  • Digital filters to remove resonances: 3 x Notch filters, 2nd-order low-pass filter
  • Bug fixed: upside-down settings lost after switching to different profile
  • “Frame upside-down” command now inverts RC control for YAW, together with inverting YAW motor and rotating second IMU
  • Bug fixed: should  ignore CMD channel during system init
  • MOTORS_ON command resets system to home position
  • New option for second (frame) IMU: “Below YAW + PID source”. It means, if Frame IMU is mounted below YAW motor, it can be used as data source for PID controller, and in some cases can give better result, than main IMU.
  • (GUI) UI elements re-arranged to adopt new settings and make groupping more consistent
  • (GUI) Separate LPF setting for RC and Follow Mode
  • (GUI) New setting “RC Inverse” (you can use it or switch Min. and Max. angles, as before)
  • Last used profile is saved as default when switched by service button, RC CMD command of from GUI.
  • Bug fixed: s-bus fast mode was not decoded correctly
