anyone know of a case that will also accommodate the lcd?
also, I made a slight change to PiMinerInfo.py since if you have multiple pools, it doesn't actually know which one you are currently mining on

hmm … so the hubs are *not* connected in a series/chain, correct?
I haven't tested with more than six erupters myself, so you have me at a bit of a loss here.
Shot in the dark, but have you tried specifying ttyUSB13 & ttyUSB14 even though they don't show with ls?

Thanks for the ideas and feedback.
To answer your question - you are correct, the hubs are not in series, but rather connected in a hub/spoke style. (RPi -> Hub1. Then Hub1 connects to Hub2, 3 and 4 directly.)
I did not try specifying ttyUSB13 & 14, although that is a great suggestion.
I'll try it in a few days when I get back in town, and post my results back here.
Laserhorse,
Can a backup pool be put in the .conf? I added a pool while mining and hit 'S' and 'W' but it didn't change anything. What about other options can be added, like difficulty?

yup - add'l pools can be added to the conf file like so:
Code:
"pools" : [
{
"url" : "FIRST POOL ADDRESS:PORT",
"user" : "WORKER NAME",
"pass" : "PASSWORD"
},
{
"url" : "SECOND POOL ADDRESS:PORT",
"user" : "WORKER NAME",
"pass" : "PASSWORD"
},
]
{
"url" : "FIRST POOL ADDRESS:PORT",
"user" : "WORKER NAME",
"pass" : "PASSWORD"
},
{
"url" : "SECOND POOL ADDRESS:PORT",
"user" : "WORKER NAME",
"pass" : "PASSWORD"
},
]
And yes - you can add a pool or make other changes from within cgminer:
hit "S" to go to settings,
then "W" to write the config file
and save it by entering the following location: "/home/pi/cgminer.conf"
and enter "y" confirm that you wish to overwrite the preexisting file.
Thanks for the great project, LaserHorse.
My Pi Miner has been running great for the past week with 9 Erupters. But, I'm having a problem adding more Erupters to it and hope that someone may be able to share some guidance.
When trying to add 6 additional Erupters (for a total of 15), I discovered that it will only "see" 13 total. i.e., typing "ls /dev/*USB*" only lists ttyUSB0 - ttyUSB12, even though there are 15 Erupters installed.
A few notes:
Any recommendations for troubleshooting this? Is there a default max number of USB serial devices that are enumerated in Raspbian?

A few notes:
- I built a second RPi Miner, with a newly imaged SD-card, and ran into the exact same issue.
- The 15 Erupters were installed across 3 DLink DUB-H7 hubs, 5 in each hub. So I don't think its power related.
- These 3 hubs feed into a 4th hub which is connected to the RPi.
- I'm using Raspbian, and followed the build process specified in your project walk-through.
- The 2 Erupters that it wont see are running fine on a separate RPi miner. So it doesn't appear to be a hardware problem with those Erupters.

FYI, I also experienced issues with Block Erupter USB's on Raspbain. However I was successful at building and running cgminer from git (3.3.1) after dist-upgrading Raspbain from wheesy to jessie.
Thnx - good to know! I'll update the tutorial once jessie is considered stable.
Quote from: The tutorial
Note: this is not the latest version of cgminer, at the time of this writing, the current version (3.3.1) has issues communicating with Block Erupter USB on Raspbian

I'm totally in love with this project! Will be adapting it for BFL Jalapenos.
Post progress Hy, ok, but why i cant not use two IPs... so when i will check the miner over CGWatcher or anything...
In "cgminer.conf" try replacing this line:
Code:
"api-allow" : "0/0",
Code:
"api-allow" : "0/0, W:127.0.0.1, 192.168.0.142",
Another question : can i change the color on startup to green? And change the glow of the display ?
I am new in this

You can edit the file named "PiMinerDisplay.py" to change which LCD colors can be selected.
The list of colors is defined starting at line #19:
Code:
self.col = (self.lcd.ON, self.lcd.OFF, self.lcd.YELLOW, self.lcd.OFF,
self.lcd.GREEN, self.lcd.OFF, self.lcd.TEAL, self.lcd.OFF,
self.lcd.BLUE, self.lcd.OFF, self.lcd.VIOLET, self.lcd.OFF,
self.lcd.RED, self.lcd.OFF)
If you'd prefer to only use green, you can replace those 4 lines with this line:
Code:
self.col = (self.lcd.GREEN, self.lcd.OFF)
EDIT: you'll also need to change line #51 in "PiMiner.py" from:
Code:
lcd.backlight(lcd.ON)
Code:
lcd.backlight(lcd.GREEN)
Just remember to keep the indentations as seen above, or python may bite
The only other LCD function which can be controlled is the display contrast, which can be altered using the onboard potentiometer
Hope that helps!
now its running. But, why? : Here is my old config file
[…]

comparing the files, I see the following differences:
likely the api-allow address
also cgminer 3.1.1 doesn't use hotplug

With 40 B.E. CPU occupation is at ~45%, so I think it can handle up to around 60 of them. The problem are USB hubs. For some reason the installed USB controller can't handle very well those hubs made with two cascaded hub internally. And I didn't find any (not expensive) solution to hook more than 20 devices reliably and 40 devices with stability problems. I would be happy to being able to connect 40 to 60 devices, I'm still looking for a serious USB HUB.
Code:
"api-allow" : "W:127.0.0.1, 192.168.0.142",
maybe the space between the 2 ips?
cgminer 3.1.1 on my desktop accepted your old config without any fuss...
I'm certainly no expert, but I notice on line 8-9 the comma is in different place. When I had trouble with mine it was formatting errors like that. (I think)

Strange, I'm unable to recreate this bug - PiMiner always manages to connect to cgminer for me, tho it can take up to ~30 seconds or so.
Which version of the RPi are you using - Model A or Model B?
I'll check a few more possible causes …
I have Raspi Model B.
CG Miner 3.1.1
On one screen i become the message
"format
error"
when i push the up or down button.
i use german language config in raspi.
so in Germany we work with comma, for numbers eg. 1.000 in English is 1000 in German and the comma is for *,00
i dont know if this the right way... but a idea.
Where can I buy assembled Adafruit 16x2 LCD display? Thank you.
Drop me a line if you're still looking. I'm selling assembled and tested ones for $45 shipped.
