Modular Python Bitcoin Miner - Official Thread

[TheSeven]

Modular Python Bitcoin Miner

The Modular Python Bitcoin Miner is a very flexible mining software written in Python, aiming to unify the frontend of FPGA-based mining hardware.

Features

• Runs on Python 2.6+ / 3.0+
• Very flexible, to allow for all kinds of weird mining hardware and future mining pool protocols
• Multi-pool support (load balancing or failover, configurable)
• Multi-worker support
• Worker hotplug support
• Web interface
• All UI functions available through JSON API
• Can easily handle clusters of tens of gigahashes, dependinding on the board type

Supported devices

• Simple RS232-based interface, as a starting point for interface developers
• X6500 FPGA mining board (no need for D2XX driver!)
• Icarus board
• ZTEX boards
• Butterfly Labs (BFL) BitFORCE Single
• ...more to follow!
• Feel free to implement your own one!
• Board vendors: Contact TheSeven with an offer (e.g. a board for testing) if you want your board to be added!

so without the D2xx-drivers we could get this thing running on OpenWRT?

[TheSeven]

so without the D2xx-drivers we could get this thing running on OpenWRT?

That depends on:

• Availability of /dev/bus/usb
• Availability of libusb
• Availability of python
• Available RAM etc.

[O_Shovah]

Is there a more detailed description for setting the scripts up avaidable ?

I tried running it on my linux maschine but i keep getting errors for a common file.
I guess my Pm to you dindn't reach you. Seems to be unreliable lately.

Am I missing something?

Looks great.

That sounds like you're using Python <2.7 to me. Only 2.7 and 3.x is supported.

@O_Shovah: I've responded to your PM now... Looks like common.py is missing for some reason? (I have no idea why...)

[kronosvl]

Sub'd

same here, specially openWRT oportunity

[thirdlight]

That sounds like you're using Python <2.7 to me. Only 2.7 and 3.x is supported.

Yes, 2.6.7 as standard for X6500.

I tried 2.7, log has:

How do I get usb module?

Thanks

http://sourceforge.net/projects/pyusb/files/PyUSB%201.0/1.0.0-alpha-2/pyusb-1.0.0a2.zip/download

you can just unpack the "usb" directory from that zip file into the mpbm directory, or install it system-wide using setup.py

Hi.

Looking really good!

Couple problems with v0.0.4alpha that I can see:
1) curses line characters are all messed up in my locale  (en_AU.UTF-8) (let me know if you want a screenshot)
2) I'm getting "Invalid long polling URL for Slushies: http://api.bitcoin.cz:8410"

Thanks for this work, i'm loving the idea of one program to run ALL the FPGA's.

I'm getting this error:

[LazarusLong]

I was working on a port with libftdi to replace the d2xx lib - it did not work, some bits in the data streams differ.
Great work! I really need this stuff on openwrt...

[thirdlight]

Thanks, TheSeven. I bet you underestimated the level of hand-holding some users need!

Now getting:

Code:

2012-02-07 08:34:53.468000: Caught exception: No backend available

Not getting quite as far as coblee, as no board serial detected?

[coblee]

Well, I put the serial in the config.py myself:

Code:

  # Single X6500 worker
  { \
    # Worker module
    "type": worker.fpgamining.x6500.X6500Worker, \
    # Worker module parameters, in this case board serial number (default: take first available)
    "deviceid": "AH00WOWD", \
  }, \

  # Single X6500 worker
  { \
    # Worker module
    "type": worker.fpgamining.x6500.X6500Worker, \
    # Worker module parameters, in this case board serial number (default: take first available)
    "deviceid": "AH00WI18", \
  }, \

1) might be curses not properly detecting your terminal type. Running it inside a screen session sometimes helps with this. If you're using PuTTY as a terminal, make sure to set its charset to UTF-8.
2) MPBM probably expects a trailing slash here... I'll fix that later today.

I'm getting this error:

2012-02-06 20:25:26.472938: X6500 board AH00WOWD: No backend available

Sounds like you don't have libusb installed or a weird version of it.

Well, I put the serial in the config.py myself:

Code:

  # Single X6500 worker
  { \
    # Worker module
    "type": worker.fpgamining.x6500.X6500Worker, \
    # Worker module parameters, in this case board serial number (default: take first available)
    "deviceid": "AH00WOWD", \
  }, \

  # Single X6500 worker
  { \
    # Worker module
    "type": worker.fpgamining.x6500.X6500Worker, \
    # Worker module parameters, in this case board serial number (default: take first available)
    "deviceid": "AH00WI18", \
  }, \

If that works, autodetecting should have worked as well.

2) I'm getting "Invalid long polling URL for Slushies: http://api.bitcoin.cz:8410"

Fixed

MPBM should now be compatible with Python 2.6 as well.
Thanks to LazarusLong for providing the patch

[thirdlight]

I've had mpbm working using "useftd2xx":"true" and python 2.6.7.

It saw all the boards, but couldn't "open" all of them.

Seemed to be getting shares, pool reported widely varying hashrate. The terminal window has a message about "window too small" so no stats to relay.

Froze around an hour later, no reason in the log.

I like that it manages (or tries to) all the boards at once - much neater than multiple windows. I will persevere.
