cgminer 4.8.0-scrypt (zeus / gridseed / lketc support)

CGMiner 4.8.0 with GridSeed, Zeus and Lketc with Scrypt ASIC support.

This file describes Lketc-specific settings and options.

For general CGMiner information refer to doc/README.

LKETC usb miner

This code is forked from original cgminer-dmaxl-zeus.

I made a custom driver for LKETC usb miner that you can find on ebay, like this:

My code is base on Zeus scrypt Asic, but I made some changes to enable possibility to use Zeus and LKETC as same time (with tuning for each kind of miner)

Why a separate driver instead of using zeus driver ?

because lketc stick , they are clone of zeus but with cheaper component.

In most case, they need a lower frequency to run properly. If you have a mix of zeus and lketc in your rig, it will interresting to separate zeus and lketc setup.

to build this specific code:

sudo apt-get update
sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl4-openssl-dev libudev-dev \
libjansson-dev libncurses5-dev git libzip-dev

git clone https://github.com/wareck/cgminer-lketc.git
cd cgminer-lketc

sudo usermod -a -G dialout,plugdev $USER
sudo cp 01-cgminer.rules /etc/udev/rules.d/

CFLAGS="-O2 -march=native" ./autogen.sh
./configure --enable-scrypt
make
sudo reboot

Option Summary

  --lketc-clock <clock>   Default chip clock speed (MHz)
  --lketc-options <ID>,<chips>,<clock>[;<ID>,<chips>,<clock>...]
                         Set chips and clock speed for individual devices

  --lketc-nocheck-golden  Skip golden nonce verification during initialization (serial mode only)
  --lketc-debug           Enable extra Lketc driver debugging output in verbose mode

The following three examples are equivalent assuming two miners are connected:

# Using libusb
./cgminer --scrypt --lketc-clock 280

# Direct serial I/O, manual port specification
./cgminer --scrypt --lketc-clock 280 --scan-serial /dev/ttyUSB0 \
	--scan-serial /dev/ttyUSB1 --scan-serial /dev/ttyUSB2

# Direct serial I/O, auto-detect ports (Linux only)
./cgminer --scrypt --lketc-clock 280 --scan-serial lketc:auto

Exemple If you use Lketc and a Gaw Fury :

./cgminer --scrypt --lketc-clock 280 --zeus-chips 6 --zeus-clock 328
