Alternative ESC firmware (reflashing)

[ziss_dm]

Hi Wishnu,

pwm_fast_200 - range 1100-1900us
pwm_fast_250 - range 1000-2000us

So, most likelly your transmitter was not able to generate 2000us pulses.

how to attach wires to blueseries 12A ESCs? Those have no pads and I cannot solder to the tqfp atmega8 pins directly (no appropriate tools and insufficient eyesight even with mag-glasses). I had hopes something like a socket type thing would exist that could be used - but came up empty.

I own 8 of these ESCs I want to use but cannot currently convert. Any advice how to proceed or any volunteers for a round of brewery produce?

This page on the OpenPilot Wiki lists a number of possible approaches. I like the one where they used modeling clay

Hi Hamburger,

I have committed small change which allows you to adjust timing advance..

Code: Select all

#define    TIMING_ADV          0|1|2|3


I think, slightly increasing timing you can regain power loss, but probably in expense of efficiency.

Hellow ziss_dm,
can i somehow limit the range 1100-1700us instead of 1100-1900us?

I built an adapter with modeling clay (tradename FIMO) and pogo pins for blueseries 20A P/N-fet with pads not in row. Flashing with the adapter works sometimes (1 out of 8). very cool.

Hi ziss_dm,
will test and report back asap.
Thanks, Hamburger

Do you mean limit max power or scale power within narrow pulse range?

[Wishnu]

I mean limit max power

[ziss_dm]

Hi Wishnu,

There is a way to limit max power (you need to modify <input>.inc or better to create your own one):
