  • Date: Sat Aug 27 15:41:01 2005

Hi Peter,

Sorry for the delay in response, but was on holiday for a few weeks.
I made the change in the code, and add some documentation in hd44780_howto.txt (section 1.7).
Follow the patch (as an attachment this time !).


Laurent.

Hi Laurent,

would you please be so kind to - send the patch as attachment (instead of inline).
This keeps the spacing korrektly
- update the copyright statements in the files
(especially: mine/server/drivers/hd44780-lis2.c)
- add documentation (similar to the other hd44780
connetion types)

Thanks in advance
Peter

It does not support a keypad nor backlight switching.

+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.
