Hey everyone we are able to release a tool that allows you to adjust your voltage settings for your Evo and Habanero boards.

HF has provided us with a python 3 script that we are allowed to distribute.

Basically in a nutshell this is good to use ONLY if your trying to push your boards past 900Mhz because you will need to increase the voltage on the board in order to give the chip more power.

USE AT YOUR OWN RISK, please read the LICENSE FILE first before using this tool.

This only works with one miner plugged in at a time!

The hftool.py utility is used to query and manipulate hashfast module settings.

Requirements:
Python 3.x
pip for Python 3.x
Pyusb

Installing pip for python 3 on most unix systems (command for ubuntu below)
sudo apt-get install python3-pip

hftool requires pyusb. To install it:
pip3 install --pre pyusb

Put these into a file /etc/udev/rules.d/01-hashfast.rules:

You will need root access to create this file and also when done its recommended you reboot in order for these rules to take effect.

Code:

ATTRS{idVendor}=="297c", ATTRS{idProduct}=="0001", SUBSYSTEMS=="usb", ACTION=="add", MODE="0660", GROUP="plugdev, ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="297c", ATTRS{idProduct}=="8001", SUBSYSTEMS=="usb", ACTION=="add", MODE="0660", GROUP="plugdev", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2ff6", SUBSYSTEMS=="usb", ACTION=="add", MODE="0660", GROUP="plugdev", ENV{ID_MM_DEVICE_IGNORE}="1"

RUNNING

Start the tool by with:

Code:

$ ./hftool.py -h

Read die frequencies and voltages:

Code:

$ ./hftool.py -r

Write die frequencies and settings:

Code:

$ ./hftool.py -w 0:VLT@FRQ,1:VLT@FRQ,2:VLT@FRQ,3:VLT@FRQ

example would be setting all dies to .930 volts at 875Mhz

Code:

$ ./hftool.py -w 0:930@875,1:930@875,2:930@875,3:930@875

You can grab it from Bitbucket Git depo here https://bitbucket.org/gateway69/hf-tool

AND no I dont work for HF, we pushed them to get a tool released so our customers of our Habanero boards could tweak and push their boards.

Thanks for sharing this informative post...building it and doing it great!
