Flashing Turnigy Plush 25A Silabs ESC with the BLHeli Firmware

29 January 2015

This is how I flashed my Turnigy Plush 25A (Silabs) ESCs with the BLHeli firmware. BLHeli Firmware is the alternative of SimonK to the ESCs with a Silabs chip, and offers higher response of the motors from the stock firmware. It also offers a GUI to program the ESC and lots of features to tweak from.

Required tools/materials/software

  1. Soldering iron
  2. Arduino UNO
  3. Turnigy Plush (Silabs) 25A ESC
  4. Jumper cables (3 for each ESC)
  5. BlHeliSuite

Instructions:

  • Solder the 3 jumper cables to the pins as shown in the following picture. Purple is the C2D and goes to the MISO pin of the ICSP port of Arduino – Green is the C2CK and goes to the MOSI pin and the Red is the Ground.

  • Connect the Arduino to your computer
  • Connect your lipo to the ESC
  • Download and Start BlHeliSuite.exe
  • Menu “ATMEL/SILABS” -> “SILABS Serial Interface”.
  • Tab “Interfaces for Silabs” will show up. Select the port that the Arduino is connected to.
  • Select “ATMega328P” and click “Make Arduino General”.
  • Select “Arduino_m328P_16_MULTI8v12100.hex” from the new windows.
  • Hopefully the Arduino Firmware is uploaded to the Arduino.
  • Tab “Silabs BESC Setup” Choose the port that the Arduino is on and press connect.
  • Then press Flash BLHeli –> Choose your ESC. I chose the Turnigy Plush 25A Multi hex 12.2 version hex.
  • Now by pressing the “Read setup” you get your ESC’s settings.

After flashing all of the ESCs with the BLHeli firmware I did a throttle calibration through my APM 2.6 and everything worked flawlessly. And the difference from the stock firmware was huge

  1. Day and night, for what, acrobatics, response, smoothness, battery life? At the moment I’m interested just in battery life. The dampening increases quicker sharper responses, but doesn’t waste that energy, to break the engines on purpose. How is the battery life on casual flying compared to original firmware?

    1. No visible changes in battery life.
      Changes in smoothness and response for sure. Battery life is my number 1 priority too.
