its probably just windows 8. its a real stupid OS, really annoying sometimes. would be useful if Microsoft made two different OSs for different users (advanced and a simpler one) so you can do what you want to do with out the limits and restrictions of the simplified windows 8.
Shakesc would you mind talking me through exactly what HK software you've used please?
Thanks to everyone for their help
Hi
I used a windows 7 machine. My other machine is Mac. Might try that at some stage , I believe KK s/w is just a Java app
Downloaded the KK multicopter flash programming software, see
http://lazyzero.de/en/modellbau/kkmulticopterflashtool
The USBAsp drivers can be a little fuzzy to install. If they are an issue then have a look at
http://www.fischl.de/usbasp/
and for just the drivers
http://www.fischl.de/usbasp/usbasp-w...2011-05-28.zip
I also did what Dan said and used a plug for the gnd wire
Just saves some soldering
Done it! Thanks for the help everyone. It's not the most user friendly piece of software but the KK multicopter worked a treat.
Now I just need some cable to handle the amps, nearly set the fire alarm off today burning through some T&E.
What's wrong with the cable on the turnigy 85a controllers? Should be more than up to the job for some drills etc
We're using something slightly larger than drill motors and very Bitza. Although I was surprised that it ate any cable!
Those wires should be plenty big enough. If those go up I'd be more worried about the rest of the esc going up first.
The wires on the ESC were fine, it's the rest of the loom that was showing the strain.
Ah right I understand what you guys mean now
hi all,
Was wondering if someone could help me out. I'm a complete noob when it comes to computer programming and i would love to learn but Im a little pressed for time due to work, family commitments and all the other problems I'm having with the bot (the control isn't working either but i think this may also be down to the ESCs translating the commands into movements).
If possible, could someone much cleverer than me please compile the latest code for me into a .hex file (i think this is the link to the latest C code file although i may be wrong: http://bazaar.launchpad.net/~brushed-te ... ushedESC.c ) so that i can reflash my ESCs and hopefully solve some of the problems.
Forgot to say that what i need changed in the code is the TEMP_LIMIT set to 0 . This will then turn it off as the temperature limit which triggers the thermal protection to kick in is quite low really. My bot died after two minutes because of this
Cheers
Dan
ok lads I would like to know if any one can help me out please
I have one of these controller's which I need to mod the problem is the picture is different to solder points onto ie the top corner MOSI and SCK
thanks inadvance
The circuit board is different to the one pictured on the tutorial?! If that's the case, Steve and Aaron at botbitz would probably be the best people to ask.
just adding a pic so Gary can show us :)
This one perplexed me for a while when I first took a look at the board but it's fairly straight forward. Seems the boards have been updated in the time since that tutorial was written. Image showing soldering locations below.

thanks I was going to guess them 2 but just making sureQuote:

Literally that's all that's required
Cheers! Will give it a go
What do you need to program on them, is it settings such as battery type, mixing etc? and how is it actually done.
Thanks
You need a programmer, a soldering iron, good skill with a soldering iron and a computer with the appropriate software. Read through the links ast the start of this thread for details. When we talk about reprogramming we are changing the fundamental program that the speed controller uses. Think of it as changing a computer from windows to linux
Gary, the ISP connector you showed me at the champs, did you get it from the website link provided on the Robowars forum page (http://littlebirdelectronics.com/pro...-connectors-12) or somewhere else? Just seeing if I can find a closer supplier than Australia.
EDIT: eBay might have me sorted actually http://www.ebay.co.uk/itm/Custom-len...item4d0bccf4837
EDIT 2: Scratch that, just noticed the cable is provided with the Pololu AVR programmer
Yeah you get a cable with it. Let me know if you need a spare though. I bought a few spare cables as I also wanted to use the programmer to program an orangutan chip.
@Gary can you post how you get on withe Orangutan chip? I would quite like to get one for an Ant.
Played with it about a year ago for an experimental melty brain spinner
Thanks, I`ve done a bit of reading and it looks simple enough. Will any AVR programmer work or does it need to be certain ones?Quote:

I would recommend the pololu avr programmer. Didn't have any issues with it
ok thanks I'll get that one.
Didn't see much point posting a new topic about it so I just thought I'd just ask here - does anyone happen to know how much it would end up costing for 2 of these hacked BotBitz ESCs, including postage and packaging to the UK? I know it comes to about £80 for the two not including the postage so, not sure if it's worth just attempting to hack some myself if I can find a guide on the internet...
Thanks in advance!
Have a look at
http://www.robowars.org/forum/viewtopic.php?t=1609
Ordered two a couple of days ago, it came to £94 including postage. That was converted from Australian dollars.
That include import tax at 20% and handling of around £8.50 for parcel force?
Programming them is far far cheaper
No doesn't include that as they havnt arrived yet.
I plan to program my next ones but I got these due to lack of time available before Newport.
So guys I am currently working on V2 Firmware for our controllers.
As some of you may know I have already reverse engineered one of the programming boxes from HK.

I am working on finishing this off and adding even more features.
See: http://robowars.org/forum/viewtopic.php?t=1893
This will be used to make all of the settings configurable out in the field. This will give you the ability to tweak your robot on the fly.
The one which I am most excited about is being able to reverse my speed controllers as at an event as I always seem to bloody solder the wires on backwards when I replace a motor. The other thing which is interesting is that I drew up ways to make ESCs into on/off switches by just changing parameters. This is not that interesting for the TZ85A but for the 10A ESC it provides an easy way to get a cheap RC switch for triggering weapons.
For those who are programming ESCs themselves this won't be open source. But for those who have had DX6is this should make all your problems go away.
I also aim to provide the tools to read parameters from your current robot and ESC setup to allow you to dial in your driving and tweak your ESC so that it gives you the best possible control and performance. Oh and it will also have serial control if you want to use ESCs in an automation type application.
Well that is the plan. Hope to have new firmware done in 1-2 weeks and decent testing will take a month or two before I am willing to release it. For people who have currently bought ESCs from BotBitz we are looking at offering a upgrade program, if there is interest let me know.
Regards
Steve
These arrived yesterday so about three weeks for delivery.Quote:
