Display
The LK204-7T-1U
is an intelligent alphanumeric liquid crystal
display designed to decrease development
time by providing an instant solution to any project. In addition to the RS232, TTL and I2C
protocols
available in the standard model, the USB communication model
allow the LK204-7T-1U
to be connected
to a wide variety of host
controllers.
Communication speeds of up to 115.2kbps for serial protocols and
100kbps for I2C
ensure lightning fast text and graphic display.
The simple command structure
permits easy software control of many settings including backlight
brightness, screen contrast, and baud rate. On board memory provides up to forty
custom characters
which can be saved within the unit and recalled for start screens, bar graphs or larger numbers.
User input on the LK204-7T-1U
