Display your cgminer Stats on a small LCD Display (cgminerLCDStats)

[cardcomm]

Hi Everyone,

I like to take a minute to introduce a new monitor app for cgminer. This simple script will get data from the cgminer API and display mining statistics on a small LCD screen attached to your computer or Raspberry Pi. It's a great addition to most unix based mining setups, and includes a handy MtGox ticker and clock display as well. It's been verified to work with most Linux distributions, Apple OS X, and as I said, works great on the Pi.

The project website is here:
http://cardcomm.github.io/cgminerLCDStats/

The code can be downloaded here:
https://github.com/cardcomm/cgminerLCDStats

Here is a screen shot of the display in action:



You can order the specific LCD screen needed for this app from the ColdTears Electronics ebay store:
(Note that I am IN NO WAY connected with ColdTears electronics, nor am I endorsing this ebay seller. I've personally ordered and received two units, and I know several others have purchased them as well.)

I first heard of this display in a post on the MinePeon forum. There are quite a few posts in that thread discussing the LCD display and this project.
BTW, the code to support the LCD display is rolled in to the current release of MinePeon.

A little bump to make sure everyone gets a chance to see this...

[Trongersoll]

that is pretty sweet.

Does it need to be connected directly to the Pi and not via USB hub? I'm having issues getting it to be seen when running the  sudo python2 cgminerLCDStats.py" command.

Just ordered one. Can't wait to get it going.

Just a heads up.

LOL! Thanks. I can't tell you how many times I've made that typo :/

No, it should work fine when connected to a hub. I've seen a number of these units with defective USB cables, unfortunately. They tend to fit very loosely at the connection near the display. Does the Display work for any of the demos?

What specific error are you getting? I'm assuming one about "not being able to claim the device". It's usually either a bad USB cable, or not running the script as root. (that does not seem to be you problem)

It powers up, but using the command lsusb doesn't bring it up.

Next time I am back home, I will try another USB cable and actually try it with the default software. Will get back to you.

This display would be perfect for the GPU/ASIC rig I just spun up...will probably have to roll my own software to poll two cgminer instances and two CryptoSwitcher instances, but the pointer to a suitable display is useful info.

The Python code should be a good starting point for that. It already supports being pointed to an arbitrary cgminer instance. You would just have to add code to poll the two separately.

Hi im  trying to get this screen to work with bfgminer but i think there is some difference between it and cgminer and a it just hangs at what looks like getting the api info anyone have any idea what need changing ?

Hi,

I haven't tested with bfgminer at all, and I'm not very familiar with it. I  think the API is similar, so it may work. You'll need to make sure bfgminer is listening for API call. I think you need something like this in the bfgminer config file:

"api-listen" : true,
"api-port" : "4028",

I hope this helps. Let me know if you get it working, or if I can be of further help.

Turns out the one I got was a dud, the USB connecter is broken and only receives power, no data. Time to open it up and see what I can see!

EDIT: working now. Just hit the USB connector with my rework station and all is working.

Cheers for a great little script OP!

Sweet! Congrats on the repair.

I'm kinda noobie to Linux - but I have a question:

I use SSH to access my rPi and I can get it running easily. However - is there a way so i can still sudo screen -r on cgminer so I can monitor the miner when I am on my other computer?

Any way around this?

Pretty sweet, thanks for sharing.

Implemented a quick dirty fix which gets it working with bfgminer

changed CgminerRPCClient.py

Code:

# loop until a zero byte indicates we got all the data
            data = ""
            while True:
                buffer = s.recv(65535)
                if '\x00' in buffer:
                    data += buffer # keep the buffer and bail from the loop - we got all t$
                    break # zero found, so we must have all the data TODO break in loop is$
                else:
                    data += buffer # No zero found yet, append current buffer to data and $

            s.close() # close the socket

To

 # loop until a zero byte indicates we got all the data
            data = ""
            while True:
                buffer = s.recv(65535)
                if buffer:
                    data += buffer # keep the buffer and bail from the loop - we got all t$
                 # zero found, so we must have all the data TODO break in loop is ugly    $
                else:
                      s.close() # close the socket
                break

Your my Hero. This Works for BFGMiner. I now at last have a stable Minepeon Build.

How to get the screen to run on boot?

Edit  : found the answer on minepeon forums

All is right with the world once again.
