cgminer-scrypt
==============

CGMiner 4.3.5 with GridSeed, Zeus and Lketc scrypt ASIC support.

This file describes Scrypt-specific settings and options.

For general CGMiner information refer to README.

Scrypt algorithm code was ported from CGMiner version 3.7.2.

## 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)

to build this specific code:

	./autogen.sh
	./configure --enable-scrypt --enable-zeus
	make

### 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 --lektc-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
