Re: GridSeed 5-chip USB miner voltage mod

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

Thanks sandor

Do you think it's possible to add an option to cpuminer to detect automatically the gridseed devices? Of course you will not be able to set per device freq with this option on but it would be useful to start the command in autotune without writing every single dev in the launcher string. I think looking at the dev ID do the job, Gridseed has always 0483:5740 as ID.

I used a bruteforce search method with this script:

#!/bin/bash
# options
NUM_DEVS=2

# initialize an Array
DEV=(/dev/ttyACM0,/dev/ttyACM1);

## Script Begin ##
COUNTER=0
FOUND=0
echo -e "Searching for devices...please wait\t"
while (( 1 )); do
if [ -c /dev/ttyACM$COUNTER ]; then
DEV[$FOUND]="/dev/ttyACM$COUNTER";
(( FOUND++ ))
fi
if (( $FOUND >= $NUM_DEVS )); then
break
fi
((COUNTER++))
sleep .5
# Change Counter value check based on number of devices
if (( $COUNTER >=10 )); then
echo -e "Found only $FOUND devices out of $NUM_DEVS...Please check USB connections & devices.\n\nExiting...\n"
exit 1
fi
done

echo -e "Found devices ${DEV[0]}, ${DEV[1]}\n"
### End bash script

HTH...
