This is a major bummer as the default software on the atmega is absolute sh*t. The motors often don't start and when they start it often loses timing blowing the fuse as it runs dc through one winding.

The RCTimer 50A is like this, too, but the trace is not under the chip. Maybe you could tie the output to the reset pin and then it would burn off the trace for you.

Can someone tell me if one of these (Pomona PLCC Quad Clip Test Adapter, 32-Pin) will work for flashing ESCs? I know it is expensive.

I have successfully flashed two (out of two) with the tp.hex firmware.

Hi Simonk,
Which version of your firmware would you recommend to flash this ESC (Turnigy TY-P8) ?
Thanks

I haven't tested it myself and HK dropped it from my order, but if it's the TY-P1 (not sure what TY-P8 is), it should be tp_nfet.hex, as per https://github.com/sim-/tgy/blob/master/README.md.

Thanks Simonk. oh yes, I meant TY-P1 and not TY-P8... So I'll pick the last git version and flash. I have 10 to burn and see how it goes.

I saw on your readme page an interesting comment: " This doesn't yet check temperature or battery voltage. This is not desired on multi-rotor platforms; however, people still want to use this on planes, cars, boats, etc., so I suppose I'll add it."

That's true, on multikopter we don't want the ESC to cut when overheat. However, it could be cool to provide the temperature information on a dedicated wire (when available).

Hello Simonk,
Which version of your firmware would you recommend to flash this ESC..?

And how do I go about reading and saving the stock SW/FW..?

Thanks

i'd guess bs_nfet, that almost looks like 20A blueseries.
You can't have original firmware, its usually locked.

timecop:

It's A 30A E Series with International Rectifier Co. n-FETs.

Also it has ZTW printed on the circuit board.

Do I use the round dots/pads for flashing...?

I looked for similar in the data base but no joy...!
