Programming Functions: Battery Type: Lipo /NiXX Brake: On / Off Voltage Protection: Low / Mid / High Protection mode: Reduce power / Cut off power Timing: Low / Mid / High Startup: Fast / Normal / Soft PWM Frequency: 8k / 16k Helicopter mode: Off / 5sec / 15sec (Start up delay)
Standard 50Hz is OK for quad.
In fact you may need more only for very aggressive acro mode flights....
Has no idea what was stock firmware freq as first thing I did I reflashed mine ones with SimonK firmware... Not because of update freq, but for easy setup and calibration.
As described here (post 1106) I've got problems to flash them with SimonK.
How did you do this? * v_max
I reflashed mine with command line avrdude
> avrdude -c usbasp -p m8 -P -b19200 -U flash:w:bs.hex:i
(assuming bs.hex file copied to same directory where )... your error message "target doesn't answer"
more likely means wrong wiring to pads...
Just check your connections with ohmmeter from atmega pins on chip (not from pads) to usbasp pins
(on usbasp board where it's labeled)....
Also.... i do not power ESCs while programming... I use powering from usbasp 5v (J1 jumper closed on usbasp board)
Is it a good choice with a Turnigy 2204 and a 850mAh 25C battery ?
Does the cut-off automatically set for 2S or should I use a programming card ? If yes can you advice me one ?
In advance Thanks !!!
2204 has max current 7.5A.. good rule have esc with max current between 1.5-2 times more then max motor current... I'd hcoose 12A one.
As for this ESC... by default it autodetect number of battery cells on startup and then do cut-off automatically. In fact you do not need programming card and programm it manually (see manual under files tab on this page) but this is a bit tricky.
Since I reflashed mine ones with SimonK firmware (I use it on x250 quad) I forgot this programming nightmare.. Often you can occasionly enter in programming mode and thus do some unwanted changes. That's was one of the reasons why I reflashed mine ones. SimonK firmware has only throttle range calibration and do not require any programming...
i replaced the stock esc of the micro f86 which is 6A with this esc in order to use 3s battery and it flies great i just cut the wires to save weight and will stay in the recommended flying weight specs.thank you hobbyking.
