1.7 LIS2 Usb device
===================
LIS2 from VLSystem (http://www.vlsys.co.kr) is a full featured usb vfd module
with four channel fan controls. This device can be access as a serial device with
help of the kernel modules ftdi_sio wich map the usb port to a serial port (/dev/ttyUSBx).
To use LIS2 with LCDproc, you will need a few settings in the config file :
[server]
Driver=hd44780
[hd44780]
size=20x2
ConnectionType=lis2
#Device=/dev/ttyUSB0
extendedmode=false
Size of the display (size=20x2), driver to use in ConnectionType: lis2, the serial Usb
device as device settings (default is /dev/ttyUSB0), and extendedmode should be left to false,
as this device don't seems to support hd44780 extended mode.
The device support only a subset of the hd44780 specification. For now, I find this function:
Function #1 : Clear Screen
Send char(0)
Send char(160)
Send char(0)
Send char(167)
Function #2 : Cursors move: (x,y)
Send char(0)
Send char(160 + y)
Send char(x)
Send char(167)
Function #3 : Write a char
Send char(asciiCode) : asciiCode 0 to 7 can be redefine to user charset (see below).
Function #4 : Redefine a char
Send char(0)
Send char(171)
Send char(matriceNum) : Ascii code of char to refine, from 0 to 7
Send char(line) : the line to change
Send char(pixel) : define wich pixel of the line is on or off.
There's 5 pixels by line, adresse by power of 2, from right to left (16, 8, 4, 2, 1).
Function #5 : Fan Control
Send char(0)
Send char(174)
Send char(0)
Send char(0)
Send char(fan1)
Send char(0)
Send char(fan2)
Send char(0)
Send char(fan3)
Send char(0)
Send char(fan4)
Send char(0)
Send char(0)
fanX is a value from 0 to 255, 0 is fan off, 255 is fan full speed.
