Great, can you please specify your interest? Are you only interested in the attiny support or is the idea of a neural network something that you can use?

the attiny85 is supported as well. I took some pictures, but you will have to wait until Monday I guess. I think the attiny84 is the better choice, I have one here in DIL14... the attiny85 has too few pins.
But if this is sufficient for your application then my modified IDE can handle this chip, yes.

And now some great news for all windows users (mac and linux support will be added later):

I managed to add the FTDI BitBang bootloader upload process into my IDE.

So from now on it is possible to use the X3 pin header of the FTDI chip of the Arduino Diecimila as an ISP programmer (as descibed in the link above).

Of course this enables you to burn a bootloader to the Diecimila itself, but I burn the bootloader to my attiny84 powered LumiNet nodes with this hack.

@darudude: thanks for motivating me, the bit bang bootloader is really working well and you can select it like any other ISP programmer in my IDE.


Awesome!! Can't wait for the schematics and IDE to release. I'm gonna order some Attinys in anticipation

Also regarding the power usage. I seem to have some problems with by arduino (I think I blew the FTDI chip). So i couldn't program it to set pins high. I did put an empty chip in (IDLE program) and got about the same power usage as you did: ~30 mA.

I am going back to the university in a couple weeks. I plan on just doing power testing an Atmega 168 bootloaded with Arduino on beadboard. This should give a better comparison between power usage on Attiny84 and Atmega168


Schematics and software will be released soon, end of April I guess.

I think the numbers of the LilyPad Arduino and an atmega168 on a breadboard will be the same.

I made a video of the BitBang upload process but I am too busy to upload it at the moment. Videos will be released soon.

Any more questions or feedback?


Update: FTDI BitBang tested with Mac OS X. It now works out of my IDE.

But I don't understand how to use the VCP driver and the D2XX driver at the same time on Mac OS. So right now the user must decide if her wants to upload sketches (using the VCP driver) or if he wants to burn the bootloader (using the D2XX driver).

But it is possible to use the FTDI BitBang hack for the Diecimila out of the  IDE under Mac OS and Windows now and I used it to flash LumiNet nodes with it.
