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

[Zeek_W]

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?

I answered this myself - I'm an idiot. Just duplicated the session in putty and entered the cgminerLCDStats.py command.

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.

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

Sweet. glad you got it working. I really need to take the time and examine the exact differences between the API's.

Sorry I've been away from the thread a while. I'm glad y'all got your problems sorted. Yeah, opening a new putty window works well to run the script. That's usually what I do. Or you could have it auto start.

southerngentuk - Glad you discovered how to set it up to auto start. I'm been meaning to add a tutorial for that, but it varies for different Linux flavors. Maybe I'll do one that covers the versions I know.

Thank you for this great project.

Maybe add a link to the git pointing to  mineforemans forum. That seems to have a lot of good information also.

Awesome! Just wish I had a spare USB port free. Would look great sitting on my router

My display arrived early this week.  I have it monitoring both cgminer instances with this quick-and-dirty shell script that just alternates between the two:

Code:

#!/bin/sh
while [ 1 == 1 ]
do
  python cgminerLCDStats.py -d 15 &
  sleep 10
  kill $(ps auxw | grep cgminerLCDStats.py | grep -v grep | awk '{print $2}')  
  python cgminerLCDStats.py -d 15 -p 4029 &
  sleep 10
  kill $(ps auxw | grep cgminerLCDStats.py | grep -v grep | awk '{print $2}')  
done

Port 4028 (the default) is an scrypt mining instance with a Radeon 6870 and a Radeon 7750.  Port 4029 is an SHA-256 mining instance with a couple of BFL Jalapeños.  Every 10 seconds, it reads one and displays it.  The running instance is then killed and the other one is started.

The only real downside is that the display is cleared once every 10 seconds.  I'm also not sure that more information (as from two miners at once) could be displayed without some lower-level mucking around in the display software to make the text smaller.  Perhaps rendering text (in a smaller font) to an image and uploading that to the display would work.

Very, VERY cool It's nice to see people getting some use out of this!

Yeah, the text size isn't something you can set, at least with the library code I've looked at. As you say, the next best bet would be to render up an image in the background and then display it. Kinda old school style

As for the screen blanking every time it's restarted - you could try commenting out line 341 in cgminerLCDStats.py:
  #   display.clear_lines(TextLines.ALL, BackgroundColours.BLACK)

Not sure that will work as expected, but it's worth a try.

Thanks for sharing your tip for monitoring multiple instances. I'll try and add that to the readme.

Took a little work, but got it running on my router:

[P_Shep]

Noticed that you're using 'stats' just to get the elapsed time... It's a HUGE transfer and elapsed time is already available in the 'summary' data.

[skleven]

Is there any chance of getting this to work in windows??

[P_Shep]

Mixed mine up a bit.
Changed the format of the uptime
Split the hash rate and blocks found and added colour (red if hash rate too low)
Added temp (displays highest temp) with colour (green -> yellow -> red)
Added colour to MtGOX text too.

[Rohks]

Looks awesome! I think I might order one of those LCDs and see if I can get it up and running for myself. Great work

[cardcomm]

This is really sweet guys! I'm SO please y'all are finding a use for my little script, and making so many cool changes to it.

This has been a long tough today - it means a lot to check this thread and see people getting use from my small effort. Awesome!

BTW, that router hack is extra cool! I love this forum

[Vertiayn]

Is there any chance of getting this to work in windows??

I actually wrote a Windows version similar to this a few months back. Runs on Windows 7, 8 and 8.1 currently for BFGminer and CGminer.

If there's an interest in it, I'll upload the code to Github.

[skleven]

Would be awsome. Have one of these displays collecting dust, and would be fun to actualy use it too. I have never in my life touched linux, and wont try either.

[ct1aic]

With the end of MtGox, is there a new version of cgminerLCDStats that could get the price of the BTC at other exchange?

Many thanks in advance.

[alleopathy]

Is that possible only tour recommended LCD display?
I've other 320*240 resolution one.
 
Thanks for your great info.

[Suave]

This is cool. How did I not see this months ago?

[wolf_miner]

Hi, my display is on the way....   was shipped from HK yesterday but i have to wait 20~30 days before it will be in my hand  .

[yslyung]

total noob on *nix ! but i still ordered the display & a Rpi. many questions to be asked for sure when both of them arrives. currently running on windows. can it work on windows ? yeah also the mtgox"ed" ticker, how to change that to other exchanges ?

awesome scrypt & idea. thx for sharing 

[yslyung]

display arrived. managed to get it installed but then the display works & switches to a screen that says "error check miner [error 5] input/output"
running on minepeon 0.2.4.4 cgminer 3.12.3 mining on OSM boards.
