Turnigy TZ-85A brushed motor hack - amended code for Spektrum Dx6i

[sam_smith]

Thanks Danjr1, i've tried an alternative usb cable I had from something else. It does the same thing so recon its busted as you say. Another one on order

Hi,
I'm planning on hacking some TZ85A, but before I order the pololu programmer I wondered if I could do it with one of these:

Which I've already got for programming arduino minis. Or can I use an arduino as a programmer (I'm sure I read about it somewhere?)
Thanks,
Max

New version of the BotBitz 85A available with a programmer box.


Allows you to adjust the low, centre and high points on each controller to suit your TX plus other features.
If anyone wants to upgrade their V1 85A's, email sales@botbitz.com.

Well my programming cable arrived from HK (Atmel Atmega Socket Firmware Flashing Tool)
Programmed 3 TZ85a in less than 5 minutes - a breeze compared to soldering on the board

I've tried to set up mixing on my DX6i by following the video but I don't have wingtailmix as an option not sure why. Anyone got any ideas?

[Danjr1]

Its in Heli mode. You need to set it to acro mode which will then show the options you need.

Ah amazing thank you!

problem the cable has a larger link end so therefore does not fit into the pololu programmer??
provided cable has 6 cores the chip cable has 10

yeah just brought that push on cable and it has a 10 pin connector the pololu programmer has a 6 pin and the programmer which goes with the cable is out of stock now its just a case of cutting 10 wires and matching them up ?
has any one done this ?
thanks in advance

I now have the push on connector that Adam had. When I reprogrammed his, he provided a 6-10 pin adapter that allowed the 10-pin plug to plug into the Pololu 6-pin plug and it worked fine. Ever since, I've not managed to get the push on connector method to work. It either would not recognise that there was an ESC connected or, more recently, would cause the ESC to go up in smoke :P (not sure if that was the direct reason)

is there any pictures so I can follow the wires etc so I can do a cut and solder ?

Using the push on block connector getting 4.4v ok but will not go into program mode any help thanks in advance

If any body going to the gaget show next week who has a programmer or push on block connector will they bring it please these are just for spares
Thanks

OK
I'm getting a little confused now, I haven't tried hacking these speed controllers but would like to start. can I have a list of equipment and/or software needed, and any information on the current procedure to do the job.
I'm not an electronics expert but if John can do this so can I.

Hi Craig,

The first post in the thread has a components list which has never really changed. It also has the videos which again haven't changed at all either. Only thing that's been updated is the ESC programming software but you can still download and use AVR Studio 4 which is shown in the vids. Its scary the first time you do it but it literally is soldering 6 wires on, plugging it in to a power source and the computer then clicking some buttons.

Hi all.... just wondering if all this is still valid?? I have dx6i and about to order my tz85s from botbits. Just wondering if the software flash is stil needed to work correctly with my transmitter as this post was a few years ago.
cheers

[Danjr1]

It is still valid but you won't need to carry out the flashing if you're buying from botbitz as they come pre-flashed with more modern code.
