-This is the README file for the MatrixOrbital display driver for lcd4linux
-
-This driver supports the serial interface alphanumeric display modules by
-Matrix Orbital Corporation (http://www.matrixorbital.com).
-
-I could only test it with the LCD2041 model, but I think every other (LCD) model
-should work. These displays are supported:
-
- LCD0821: 2 lines by 8 characters
- LCD1621: 2 lines by 16 characters
- LCD2021: 2 lines by 20 characters
- LCD2041: 4 lines by 20 characters (tested)
- LCD4021: 2 lines by 40 characters
-
-I could not test the vacuum fluorescent display models, but I think they should work, too.
-There are no entries for this models in the driver table (at the bottom of MatrixOrbital.c),
-but they could be easily added.
-
-The displays come with an RS-232 and an I2C interface. The driver supports the RS-232 interface
-only (because I have no idea how to find the I2C bus on my motherboard).
-
-Power can be applied either via an external DC power supply, a modified floppy power connector
-(be aware that you can destroy your display if you get the pins wrong!) or via the RI (ring)
-signal of the RS-232 port. I choosed the latter, and modified a serial card so that it supplies
-+5V from the ISA bus to this pin (again, be aware that this is dangerous if you connect any other
-serial device to this modified port).
-
-The driver supports vertical, horizontal and split bars (two independent bars in one line),
-all bar types can be used simultanously. As the displays only have 8 user-defined characters,
-the needed characters to display all the bars must be reduced to 8. This is done by replacing
-characters with similar ones. To reduce flicker, a character which is displayed at the moment,
-will not be redefined, even if it's not used in this run. Only if the character compaction
-fails, this characters will be redefined, too.
-
-The displays have a GPO (general purpose output), where you can connect a LED or something.
-The driver supports controlling this GPO, but this function is unused by now.
-
-
-Configuration:
-
-The driver needs/supports the following entries in lcd4linux.conf:
-
-Display: a valid Matrix Orbital Display name (e.g. "LCD2041")
-Port: serial device the display is attached to (e.g. /dev/ttyS2)
-Speed: the baud rate from the display (configured via jumpers) must match
- this value. Possible values are 1200, 2400, 9600 and 19200
-Contrast: sets the LCD display contrast to a level between 0 (light)
- and 256 (dark). Default value: 160
-
