Don't worry I don't post on any other forums.

So, generically, its a power inverter? In a block diagram would it stand alone, separate from things like the charge controller, battery murdering system, tachometer, etc.?

I take it that e*clipse will need four of these?

@paul, are you using the XC8 compiler (as opposed to xc16, xc32) or are you out in gcc land, or?

oops, perhaps xc16...

Disregard, got it compiling! XC16, had to fix some of the include statements (some case issues on ubuntu and ACController.h -> ACInductionController.h, but no biggie. My first (and perhaps last) microchip project

Code:

                        Maximum dynamic memory (bytes):          0x434  (1076)

download 300+ meg of mplab, 70 meg of xc16, create a new project for the dsPIC30F4011, add the files from the git repo (I just did induction motor), read compile errors and fix.

p.s., thank you again!

p.p.s. Nice job on the gate drivers, like $15 per gate in raw parts with desat and enough power for 600A igbt's at 10khz it seems. And a cute little attiny

p.p.p.s. Did I say thank you?

sorry, I just started copying stuff, and forgot that I named the c and h files something slightly different on the github (all because I didn't know how to actually copy the file. I've been copying and pasting file content). The other projects are more dummy links at the moment, since I was just trying to get the instructable thing done. Then I was going to fill in the details in the next week or 2. I actually used the C30 compiler.

This comment gets my vote for the understatement of the year award.

LOL p-hack. I made the fix that p-hack mentioned with the wrong name for the include files, and then added the files for the permanent magnet AC (brushless DC).

Yes. Although, you could add a few of those things with the left over pins.

I just got the board last night from e-clipse!! Beautiful work! I need to buy an "MGR" thing. I bet somewhere in Phoenix has one. I just forgot what they were called (as far as the junk yard is concerned). I'm going to go look for the name in the "MGR" thread.

I can do the code modification for e-clipse's resolver board no problem. I can't wait to test it.

Glad you like it.

Regarding the motor - the Prius, Camry, and Highlanders use a very similar motor with the same encoder. It may be easier & cheaper to locate a Prius.

I'd be happy to loan you the one I just got - I'm just trying to figure out what to do about shipping costs. Oh, I forgot to mention I just got another one and the seller messed up and sent it to me for free. Ummmm OK. . . . I need to share the universe's love on this one . . .

How 'bout this - I'll send you the one I just got, I'll cover shipping. Sometime in the future I can get something similar back - OK? If you like the thing and put it in some car - great! In other words, time is flexible and I don't need that specific one...

On the other hand, there may be one in your area - I did look previously... They would be really easy to remove from a vehicle if you found a Highlander Hybrid in your area. Let me know - I'd be happy to help.

Thoughts?

-E*clipse

P.S. Phack - you got your PIC stuff loaded under Linux?? That's really cool! I'd love to learn how.

Doooo eeet!



I'd recommend the crossbar with mounts and the rear mount. (I got the whole subframe minus the crossbar—that was pretty pointless) Also the big orange cables with it's connector, and the connectors for the low-voltage stuff.

I want to hear someone has gotten one of these spinning.

I'll happily pay for shipping! And later I'll either try to convince you to sell it, or I'll pay for shipping back to you. Just figure out shipping cost, and the paypal will arrive right after that!
