Any interest in porting over throttle calibration? I see you've departed quite a bit from my and quax' trees, so it probably wouldn't be drop-in on the Atmel side, but the concept is pretty straightforward, assuming you can fit in the scaling. I imagine the SiLabs internal oscillator is more accurate but there are probably still variances between boards, and it would be useful? Quote:

It is only the cruddy HK-SS/DragonSky/etc P/N boards that heat up and/or kill themselves. Nothing else should really run any warmer, and even those don't if you run them at the same PWM frequency as stock, which works around the electrical issues. These are the same boards that have been trying to set RSTDISBL lately. Just don't buy them. |

I'm not sure why they wouldn't work at all, but it sounds like the FETs or something are fried (though usually this is obivous). I suggest you pick up some F-20A from Hobbyking instead. See first post for links. |

Just to let you know I managed some short hops today with the reflashed ESCs and all seemed fine on the default settings The ESCs seemed to remain cool too which is very pleasing! I will do some more testing in due course, but in the mean time, many thanks for all who've made this flashing possible! David |

I've been pondering about throttle calibration, and still do not know whether it is required. The chips are trimmed to within 2%, and the voltage and temperature dependency is much less than for the Atmel. I guess we'll see if the code finds use in a multi environment. If required, I will surely look into your code Thanks, -S |

Hi all,
Anyone can do it easily that Atmel(Atmega based) Firmware Update. Please check below video.

I am trying to flash a few F-20A's using the ESC flash tool and I'm hot having much luck. I finally got the flash tool to recognize the USBasp programmer and now it says:
avrdude.exe: warning: cannot set sck period. please check for usbasp firmware update. avrdude.exe: error: programm enable: target doesn't answer. 1 avrdude.exe: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check. avrdude.exe done. Thank you. I flashed 5 F-30A's with no problem a few weeks ago. The F-20A's look identical but aren't cooperating. I have eXtreme burner AVR but don't know what settings to use for the fuses. Anyone have any advice? |

I've just flashed 4 Hobbyking Blue series 30A, those without pads and with p/n fets. ( bs.hex firmware )
It was a pain to do but I could flash them ok with bootloader. Checked just after that bootloader is ok by flashing them again with the Linker. No problem. I've wired & tested them just after. 3 of them starts ok and run without problem. One have problem like a phasis is missing ( motor jitter but doesn't start ). There was no smoke , nothing, fets seems ok. No clue yet on what's happening. F-30A are really easier to do, but there was no stock when I had to buy some new escs. |
