BitFury 16nm Stick Miner

[itsrealfast]

Just something I've been working on. I had this board designed and assembled for about 8 months now just been really busy.

Hardware is completed still working on firmware.

Need some low level developers for C programming if anybody is interested in helping out with the firmware shoot me a PM. Experts only. Dont PM me if you "learned programming last week or done it in the past"

ZERO test or expected results.

Hardware employs single BF16 with Multiplexer to mircocontroller.

Power supply voltage control range from 0.4v to 0.8v

Looks like a great project!  Ping me if you don't get a good response, but I expect you will.  I'd love to jump in but just launched some stuff of my own and I am bandwidth limited.

If you're using avr as your front end, why not flash it to arduino and do the firmware simply.  It's lame but what's the avr got to do?  Pass serial back and forth?  A bit of configuration on the front end, and after that it's grab bytes from USB and stuff into the fury.

Have you tested passing data into the mux and on to the ASIC? I had something similar rigged up back around March (the last time I had any time to work on it) but could never get it to kick on correctly.

Thanks and yes I got a couple of quick developers time to weed them out. I really dont have a preference in what IDE the developer wishes to use. Arduino will make it much easier. The BF250 is a LevelShift & MUX in one and has an SPI interface.

I haven't tested anything firmware related. I made a development board which just has the BF16 and BF250 installed this way I can send out dev boards for testing. 2-5A bench power supply will be needed. Yea I had this PCB since early last year and with no success on finding a developer I chucked it to the side. Now btc is high and I don't mind giving it another look. I have about 50 pcs each of the BF16 and BF250.

If you only have one chip on ground, do you really need the level shift/mux?

Why not pass data directly from the micro until you have the comms debugged and you want to stack more chips.

Because the signal going into the BF16 is very nonstandard, both in levels and protocol.

At worst, you just bit bang it.  What are the levels?
