Specification:
Universal alphanumeric LCD display module 4x16 characters.
4x16 LCD display
Blue backlight
White characters
The driver is compatible with HD44780.
Ability to define your characters
The standard set of libraries and sample programs downloaded with the Arduino environment includes the LiquidCrystal library, which enables the display to be operated.
Control - The display can be controlled in the following modes:
8-bit, without reading the busy flag - for transmission, you need eight data bus lines and two control lines (RS, E - RW connected to the ground).
8-bit with the reading of the busy flag - for transmission, eight data bus lines and three control lines (RS, E, RW) are required.
4-bit with readout of the busy flag - for transmission, four data bus lines and three control lines (RS, E, RW) are required.
4-bit without reading the busy flag - transmission requires four data bus lines and two control lines (RS, E - RW connected to the ground).
