NAME¶
Config::Model::models::LCDd::sed1520 - Configuration class LCDd::sed1520
DESCRIPTION¶
Configuration classes used by Config::Model
generated from LCDd.conf
Elements¶
DelayMult¶
On fast machines it may be necessary to slow down transfer to the display. If
this value is set to zero, delay is disabled. Any value greater than zero
slows down each write by one microsecond.
Optional. Type integer.
upstream_default: '1'.
HaveInverter¶
The original wiring used an inverter to drive the control lines. If you do not
use an inverter set haveInverter to no.
Optional. Type boolean.
upstream_default: 'yes'.
InterfaceType¶
Select the interface type (wiring) for the display. Supported values are 68 for
68-style connection (RESET level high) and 80 for 80-style connection (RESET
level low).
Optional. Type enum. choice: '68', '80'. upstream_default:
'80'.
InvertedMapping¶
On some displays column data in memory is mapped to segment lines from right to
left. This is called inverted mapping (not to be confused with 'haveInverter'
from above).
Optional. Type boolean. upstream_default: 'no'.
Port¶
Port where the LPT is. Usual values are 0x278, 0x378 and 0x3BC.
Optional.
Type uniline. default: '0x378'.
UseHardReset¶
At least one display is reported (Everbouquet MG1203D) that requires sending
three times 0xFF before a reset during initialization.
Optional. Type
boolean. upstream_default: 'no'.
