The LK404-25 is an intelligent alphanumeric liquid crystal display designed to decrease development time by providing an instant solution to any project. RS232, TTL, and I2C protocols allow the LK404-25 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 display updates.
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 is available through a five by five matrix style keypad, and six general purpose outputs provide simple switchable five volt sources. In addition, the option of a Dallas One-Wire header provides a communication interface for up to thirty-two devices.
