Excuse my ignorance, I am new to these forums and multicopters One quick question, can the Turnigy Plush 25A be driven at 400Hz of the shelf or are you re-flashing it ?
I'm guessing its not possible for the FC to control many PWM signals hence the need for I2C ?

Tried finding answers in these forums but there's too much information for now for me

I'm using turnigy basic 25A at 400Hz without touching anything inside or changing firmware. The only settings I changed was turn off low-voltage shutdown and change battery type to NiMH so FC handles low-battery alarm and not motors. Plush should be same? I've got some 18A plush on the way to confirm this.

And yes, at least for MK-FC, there's not enough free pins or CPU time to do PWM output to 4+ escs at once.

I confirm, Plush are the same, 400Hz with standard firmware, no problem.

hardware 8x pwm version, circuit is ok, working on firmware.

edit:
it works
AfroI2C Tokyo Drift Edition motor test [success] (0 min 52 sec)


edit2:
and flies
AfroI2C Tokyo Drift Edition - flight test (0 min 57 sec)


also: apparently there was a earthquake/tsunami here.
I didn't notice it

^_^ Yeah. I'm too far in the South. Nothing reached here even the wave.

Pants first, then shoes
Man this sucks. All the best for the Japanese. They sent rescue teams to help us in New Zealand with our recent earthquake, I hope that we can help out in some way. Unbelievable footage on the news.

Wow. Bada$$ Nice compact design. Is the jitter free one with 8 pwn outs? ie.

"TODO: A new version is in the works using proper hardware, which will allow precise PWM output on 8 channels without jitter. However, I have a bunch of boards for these, and it works "good enough", certainly as good or better as the other one."

Keep up the Tokyo Driftin' Looks smooth .

Yep, the pic + flight test few posts above is the new version - 8 hardware PWM, no jitter, slightly different layout, otherwise same size. I kept the same form factor since I didn't see any need to make it bigger.

Ya, nothing happen here at all. I'm hearing Hawaii is gonna get it though.
Hopefully you'll be ok.

Yah, nature can be cruel!

I've seen the video from the NHK copter. Incredible how the wave munged boats, cars, people and even carried burning houses miles away.

A friend of mine is in Japan right now - no message so far from him...
