I am interested in trying my hand at creating yet another FPGA cluster hasher, with each cluster connected via a single USB connection to the host (rather than 1 per FPGA).

I've looked at the Cairnsmore 1, Ztex, and Icarus drivers; each one has hard-coded some of the idiosyncrasies of those particular devices. I'm wondering if there is something like a generic CGminer driver skeleton I could fill in / develop against.

Is there a simple block of code that easily links with CGminer, passes up the relevant info from the device chain (estimated duration of one hash-cycle iteration, number of hashes completed per cycle) to the main miner program on initialization, downloads base header data and range to be hashed against from the miner to the device with each getwork or stratum fetch, receives proof of work from the device to send to the mining pool, and sends an interrupt to the device when assigned work becomes invalid?

Given the proliferation of mining devices, there's almost a need for a "miner driver" specification just like the old "packet driver" specification back in the days of Win32s enabling Win3.11 to connect to the internet, so that the people creating the new mining devices would be responsible for driver creation, rather than the mining stack software creators.

Thanks,

+1 Trying to do the same with an Arduino Leonardo acting as controller of several devices.

Unfortunately we're not a committee nor a huge team with emphasis on infrastructure and frameworks. Kano and I do this in our spare time and the model keeps changing dynamically as we progress and each new device comes along with its own new set of issues. We work on what gets things done and we have hardware to play with or care about or get sponsored to work on. This is nothing more than a hobby/pastime/passion gone mad for us.

That and I'm leaving to go overseas shortly for 6 weeks...
