OLD: BFGMiner 4.10.0: GBT+Stratum, RPC, Mac/Linux/Win64, Spondoolies SP30

[Bitcoin_Mafia_Me]

Not sure that 4.2 runs both.  If you have a Pi, check out Hashra.  They have an image for your Pi that lets you remote connect, run both scrypt/sha, and looks fairly clean.  I have yet to check it out, but I've seen good things...

Not that I'm not all about the BFGMiner, it's just a different tool if you want to do both...

No pi, just my laptop to run it with. I was under the impression that the latest ver. could do both simultaneously?

Gotten a couple BSoDs within the past 6-10 hrs.. machine auto-reboots when it happens, put the BAT file in the startup folder.. wondering what the issue may be though.

Hi Luke

I use MCP2210 because it have great stability.

I use micro only for extra caratteristic like current, voltage and temperature measurement.

Have you possibility to send information and get information to-from micro?

This could be a new cool feature for your already good bfgminer.

With GHash value and current measurement by hall sensor I could calculare performance GHash/Watt and show information by led meter.

Since I'm almost ready to send PCB please reply me soon for decide if connect and where connect this new communication channel.

After have decided the communication pin, you could develop this caratteristic in all calm and in a while I could produce pcb.

Thanks "lightworker" Luke.

What does the micro do with the information?
If the mining chip is itself controlled by BFGMiner, it can also control the clocking?
Afraid I'm missing part of the big picture here, and I can't really give good advice without understanding what the actual goals/design are.
SPI might be bitbangable for micro comms, but maybe using a chipselect would work better for that?

Hi Luke
The goal is set the device for have the best value mW@GHash (in other words best performance)

For do this I need to measure power and I already do it, but I need also to know hash rate and change number of bit.

In summary I need two function:
1 - receive hash rate
2-  set bit number

I have free pin on MCP2210 and of course free pin on micro

I think you will implement easily this 2 function.

Thanks in advice

1 pin with inaccurate timing is not sufficient for communications AFAIK.
Also, you need to define "hash rate" - there is no good way to measure instantaneous valid-result hashrate, so we'd probably need to coordinate when the averaging is reset etc.
It seems to me it would make more sense to feedback the voltage/current information into BFGMiner and do the logic there?

[pinkfloyd11]

If it is more easy then do it :-)

Maybe anyone could wrote personal efficiency algorithm in external include file.

Say me how send you this information

Thanks

Well, if we're using SPI, maybe just repeatedly shift 5555<16-bit length><data> and define data some way?

I should connect miso mosi sck in miso out mosi out sck out and a free gpio as chip select?

I'm not a hardware person, sorry.
I would think you'd want MISO/MOSI/SCK to connect to the mining chips when GPIO-N is low, and connected to the microcontroller when GPIO-N is high.
But maybe it makes it easier or more sense to just chain the microcontroller on the end of the chips?

I will ask to vladimir that is SPI GURU

I have four of the round mini gridseed ASIC miners hooked up to a USB hub. I have the latest version of BFGminer. How do I mine
in dual mode with it? Sha256 only mode?

Any help is appreciated!

Best,

Cynthia

I agree with to use Hashra for dual mining.  It worked for me and it uses BFGMiner internally.  How I am not sure, I haven't looked into it.  I will confess that I stopped dual mining because the extra Scrypt processing is more profitable currently.

Hi Luke
Vladimir say that is better connect miso-mosi-sck of atmel328 with misoout mosiout sckout of bitfury chip. Then write a driver like nf1_init (sorry but in vb.net because it is the language that I know better) and you should translate in C.
About the algorithm that manage the energetic behaviour of device, it should be written in external file "PowerManagementScript" so anyone could change it.
What do you think?

[Riley600]

Thanks, Nate.  That worked, I thought I had to replace the INF in another driver package in order to get it to work.

However, I have the same problem that Oldminer mentioned above: BFGminer find the Gridseed Orbs and mines fine for the first while.  After about 30 or so minutes, the speed drops and they eventually stop accepting shares.  I have read about the FIFO buffers and tried messing with those, but it seems to behave the same with them enabled or disabled.  Any ideas?  I'm using BFGminer 4.1 on Windows 7.

I've unfortunately never seen such an issue with any Orbs, Blades, or DMUs on any of the OSs I have setup for testing and dev.

Is there a way I can provide you with a log file so you can have a look at it and maybe identify something?  I don't think there's anything left for me to try to get it to work...

[norgan]

Has anyone got bfgminer working with an ant s1? I use bfg for everything but have no choice with the s1. I couldn't comment on which is better but it would be nice to have the option.

@Luke
Any word on getting the Zeusminers working on BFGminer yet. Theres a couple of builds running around but none of them are handling more then 2 miners for some reason. I add a third or forth miner and BFG just crashes. It is definitely not a configuration issue. Tried to make it work six ways to Sunday. Thanks

[svkochjar]

Downloaded using git clone then ./configure then  make.. Runs using default settings but does not detect RockMiner R-Box

Running on Minepeon newest build.

Thank you for any and all help

Anyone can change C code for now.
Maybe RPC can be used to enable scripting it...

[ManeBjorn]

Do you have an image that could be downloaded with all the updates like this that new users who are not great with the command line could DL and use?
Great work by the way.

I can probably create one for Raspi SD card - have never done this before and not quite sure where to upload and share this rather large image. Let me see what I can do.
