The melabs Serial LCD (SLCD) can display
serial data from either asynchronous
RS232-style or synchronous I2C input.
A range of baud rates from 2400 to 57,600
are available and the serial data is buffered
so that no delay is necessary when transmitting
data to the SLCD.
The display includes an LED backlight with
variable brightness. The serial LCD board
is also available separately for use with
other displays that utilize a Hitachi HD44780
or equivalent controller IC.
