Title: ESC Do it yourseld Firmware Flashing
Post by: Ashta on March 13, 2012, 11:56:53 AM
There is a nice thread on the above subject here
http://www.rcgroups.com/forums/showthread.php?t=1513678

Based on the above I flashed SIMON K FW on the our HK- 10A SS series ESc. The advantage is that this firmware is specialy suited for Mutirotor applications.
The main features are:

•   16MHz operation on most boards
•   16-bit output PWM with full clock rate resolution (~18kHz PWM with a POWER_RANGE of 800 steps)
•   24-bit timing and PWM pulse tracking at full clock rate resolution
•   ICP-based pulse time recording (on supported hardware) for zero throttle jitter
•   Immediate PWM input to PWM output for best possible multicopter response (eg: ideal for tricopters, quadcopters, etc., but NOT where   where slow-start or really any significant current limiting is needed!)
•   Accepts any PWM update rate (minimum ~5microseconds PWM low time)
•   Optimized interrupt code (very low minimum PWM and reduced full throttle bump
•   Configurable board pin assignments by include file
•   Improved startup (though heavy hard drives are still a bit dodgy - suggestions/patches welcome!)
•   Forward and reverse commutation supported, including RC-car style reverse-neutral-forward PWM ranges, with optional


Attched are some photos and the video.
I got some improvment on the stability, Minne was alredy stable. However i have to try the improvement in the Aerial photography

best regards

I've been reading that thread on RCG, but I remember reading somewhere that re-flashing with SimonK's f/ware makes the ECSs incompatible with their ESC programmer. Is this true?

Yeah bro, you will no longer able to change any settings as it will erase stock firmware completely but you will get new firmware specially designed for multirotor. You can calibrate throttle range though.

Timecop: You should see very fast, small oscillations, keeping the arm level. This is good.
If you get large wobbles, or the arm drops, or the motor stalls etc, the ESC response is crap.

I also posted in the multicopter tutorial thread.

I don't understand what exactly they want to show in that video.

They want to show that the response time increases after the ESCs are flashed, I guess, or that the fluctuations (unwanted) in the ESC's output signals come down when they're reflashed. :)
