Here is an example for PHP:

Code:
<?php
define
("API_MINER_START_TIME""t");
define("API_DEVICES""d");
define("API_CHIPS""c");
define("API_LAST_SHARE""l");
define("API_CHIP_ACCEPTED""ac");
define("API_CHIP_REJECTED""re");
define("API_CHIP_HW_ERRORS""hw");
define("API_CHIP_FREQUENCY""fr");
define("API_CHIP_HASHRATE""ha");
define("API_CHIP_SHARES""sh");
if(!(
$fp fsockopen("127.0.0.1"4028$errno$errstr0)))
{
    die(
"Failed to open socket");
}
stream_set_blocking($fpfalse);
$out json_encode(array("get" => "stats"))."\n";
fwrite($fp$out);
usleep(100000);
$out "";
while(!
feof($fp))
{
    if(!(
$str fgets($fp2048))) break;
    
$out .= $str;
}
fclose($fp);
$arr json_decode($out);
print_r($arr);

This will print the JSON array.
To get the list of devices you would simply do
Code:
$devs = $arr[API_DEVICES];

in the actual version of cpuminer ... the autotune feature doesn't log when it changes a per chip frequency nor the steps to go .. right?
any way to re-add that log output which showed which chip running at which freq?

Hum, does that auto tune work for the blade?
I have only used bfgminer so far with the blade unit, had issues trying to get cgminer working keeps kicking me out?

Here are my bfgminer settings, it runs around 50C right now in the basement, can run from 4.8-5.4hps max so far.

Bfgminer -S gridseed:all --set-device gridseed:clock=850:BTC=0:chips=40:modules=1:usefifo=0 --scrypt -o stratum+tcp://east1.us.stratum.dedicatedpool.com:3350 -u user -p password

Anyone have a cgminer configuration file that I can use to get this going with other mining software?

Of course it works for the Blade, it autotunes each chip individually.

Important! You MUST update to the latest binaries (Download on Github)

Fixed buggy hashrate. Reduce work being sent + optimizations. More reliable ltc reset commands.
I hope that this version will solve the issues with Blades that stop sending shares.

Your pool is sending a new job like every second, could you please try a different pool?

I think you may have found my issue as I switched it to clevermining pool which seems to be giving the miners a difficulty of 512. I had been using difficulty of 128 with my gridseeds on multipool and never modified this for the blade. Seems to not be an issue with the 5 chip gridseeds, but it must be sending work too quickly for the blades to handle. Its been up and running for over 10 minutes now so I will let you know how it goes.

Ya I think sending work too quickly will corrupt the Gridseed registers, anyhow I'm making some modifications now so that it will prevent that.

This does not have a whole lot of information , but here is what i have using 1 Gridseed Blade. https://dl.dropboxusercontent.com/u/109298881/cpuminer-gc3355.log


Do you mind posting a log with debug mode (--debug) enabled? Thanks
727  Alternate cryptocurrencies / Mining (Altcoins) / Re: [GUIDE] GridSeed 5-Chip USB & Blade Miner Support/Tuning on: May 03, 2014, 03:09:55 PM
I really don't know why. Guys, it's really helpful if you post the logs till it stopped sending shares.
If anyone wants to volunteer to help me fix cpuminer for the Blades, shoot me a PM.
728  Bitcoin / Mining software (miners) / Re: cpuminer GC3355 0.9a multiple instances on: May 03, 2014, 12:28:27 AM
Of course it's possible... and it's recommended to do so. Just add the COM ports like so: --gc3355=\\.\COM1,\\.\COM2,\\.\COM3
BTW, I would recommend updating to 0.9c
729  Alternate cryptocurrencies / Mining (Altcoins) / Re: [GUIDE] GridSeed 5-Chip USB & Blade Miner Support/Tuning on: May 02, 2014, 09:57:51 PM
i keep getting failed to open /dev/ttyACM0

I am running on Raspberry pi:
./minerd --gc3355=/dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2,/dev/ttyACM3,/dev/ttyACM4,/dev/ttyACM5,/dev/ttyACM6,/dev/ttyACM7 --freq=1000 --gc3355-autotune --url=stratum+tcp://usa-1.liteguardian.com:3335 --userpass=cxxx:x --retries=5



I have the same problem ... I'm using Kernel ... 3.10.37+

I don't have any ttyACM0 in my dev folder ... got 9 Blades connected thru 2 x 10 port usb hubs ... working well with cgminer ...

Having exactly the same issue, am I forgetting something or is there a workaround?

IIRC cgminer uses a different driver than cpuminer/bfgminer. Try modprobe cdc_acm and see if that helps.

Thank you, will try when I have time available to play with my rig.

I had the same problem trying to use cpuminer after having just used cgminer. Could not get a listing of any ttyACM devices. Quick fix was to reboot and start cpuminer without first using cgminer.

Already tried it, did not work, but thanks Smiley

Running it as root should clear up that problem.

Already tried this also but it did not help Sad but thanks anyway!

Rebooted, tried again as root... Don't know what was missing, but it works now, seems to be hashing away. Will test how it goes through the night. Activated autotune, is there an estimated time on when the autotune infos will start appearing?

You need to enable debug mode (--debug) for that info.

Anyone tried the latest cpuminer (0.9c)? Should be working fine with G-Blades now.
731  Alternate cryptocurrencies / Mining (Altcoins) / Re: [GUIDE] GridSeed 5-Chip USB & Blade Miner Support/Tuning on: May 02, 2014, 09:19:30 PM
the...

git clone https://github.com/siklon/cpuminer-gc3355

Seems to fail when I run it, even as root.

Cloning into 'cpuminer-gc3355'...
error: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none while accessing https://github.com/siklon/cpuminer-gc3355/info/refs
fatal: HTTP request failed

Update:  So I was able to download the files to a ZIP and then move them via WINSCP to the directory I created. I am logged in as 'root'.
When I try and run the './autogen.sh' command I receive the following error:  '-bash: ./autogen.sh: Permission denied'
I feel I am getting closer....

Thanks for all the input so far!


chmod +x ./autogen.sh

Whoops... fixed and updated.
Edit: current version is 0.9c now
733  Alternate cryptocurrencies / Mining (Altcoins) / Re: [GUIDE] GridSeed 5-Chip USB & Blade Miner Support/Tuning on: May 02, 2014, 02:10:03 PM
Couple of tweaks added to gc3355 code.
Binaries have been updated.

Hey you didn't update the version number. #justsayin'

Nothing major added/fixed so no need.

Hello.
So is the latest brand of Sandor's cpuminer sufficiently debugged so I can use it now without crashes or other strange anomalies? Wink
Is it stable and ready to hash 24/7 non-stop as with previous versions?
Thanks!

I have had excellent results with it on Raspbian with 20 gridseeds.

Sandor, I just want to say thank you for developing this fork of cpuminer.  It is a solid solution for those of us that want to run gridseeds on a RPi and to be able to walk away and not worry about anything.  Is the BTC address in your sig current?  I'd like to throw you a tip for making my days easier lol.

-Fuse

Thanks... yes it's current.

I have given cgminer another go and it seems to now do some hashing. Still not sure it is at the speed it's supposed to be.
I am getting on agverage 0.6 WO / minute.

Command line for cgminer I am using is:
Code:
sudo /home/syncapp/cgminer-selfcompiled/cgminer-gc3355/cgminer --scrypt --gridseed-options=baud=115200,freq=850,chips=5 --hotplug=1 -o stratum+tcp://middlecoin.com:3333  -u 1K5qx2wsjLxKZij8WdrV1rjNi6NDsdLsDc -p x

when using cpuminer I used the following command line that gave me the error message "failed open device /dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2":
Code:
sudo /home/syncapp/cpuminer/cpuminer-master/minerd --freq=850 --gc3355=/dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2 --url=stratum+tcp://middlecoin.com:3333 --userpass=1K5qx2wsjLxKZij8WdrV1rjNi6NDsdLsDc:x

You're using an older branch of cpuminer, which doesn't support multiple devices.
Try to compile this one: https://github.com/siklon/cpuminer-gc3355/

any way to re-add that log output which showed which chip running at which freq?

--debug shows the output from autotune.

Just got 3 Gridseed 5 chip miners today and am trrying to hook them up to my headless Ubuntu (13.10 - saucy) machine.

I haven't had much luck so far.

Using cpuminer (per https://bitcointalk.org/index.php?topic=454127.msg5005687#msg5005687) wont let me specify more than one Gridseed interface.
When using --gc3355=/dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2 minerd states:
Code:
failed open device /dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2

Using cgminer (using https://github.com/dtbartle/cgminer-gc3355) doesn't seem to generated any hashes.
Accepted, rejected, and work per minute stats all stay on zero.

So obviously I am missing something and would hugely appreciate a pointer to current best way of using all my miners for scrypt mining.

What is the full command line you used?

I will start a new thread when ready but in the meantime I would like to share with you the work in progress behind this new project based on sandor cpuminer.

I'd like to test it with a great bunch of pods (20 or more) but I have only 3 now, may be someone of you could test it? It requires a linux controller like a raspberry with a web server (something like a Scripta img should work very fine, just change the document root to the Minera directory).

If there is someone who wanna try it please leave me a PM, I think I will release a public beta-version next week.

Hope you like it:



Quoted for awesomeness, I applaud your efforts. Wink

Sandor111,

First thanks for all the work.

So far the new 90a work fine with my usb pod gridseeds, but it has a few problems with my gridseed blade.

1. Each 40 chip board starts off fine, 10-30 minutes in one will slowly start to slow down until no hashes are reported, then the other will stop also.
2. I am running the Pods and the Blade on separate instances.
3. Is there a way to run them both on the same instance , where the 10 pods can be auto tuned and the two 40 chip blades can be set for a hard freq?


Thanks

TC

@Anyone with G-Blades: If you could upload the full miner log with debug output, that would be helpful.

For now, seperate instances is the only way, but it's a good idea to specify which devices should be autotuned. I'll think about adding that.
