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 - |
