16×2 Character LCD Module Blue Background

Popular alphanumeric LCD display, powered by 5 V. It is characterized by simple operation, high availability and numerous support for many microcontrollers.

Controlling

The display can be controlled in the following modes:

  • 8 bits without reading the busy flag - eight data bus lines and two control lines (RS, E - RW connected to ground) are required for transmission.
  • 8-bit with busy flag reading - eight data bus lines and three control lines (RS, E, RW) are required for transmission.
  • 4 bits with busy flag reading - four data bus lines and three control lines (RS, E, RW) are required for transmission.
  • 4 bits without reading the busy flag - four data bus lines and two control lines (RS, E - RW connected to ground) are required for transmission).


The most commonly used mode of communication is 4-bit mode without reading the busy flag. Sending a half byte saves valuable microcontroller I / O output - only four data lines are used (eight are occupied in 8-bit). Failure to read the busy flag makes it necessary to use software delays, but allows to save another line - R / W. This pin can be permanently connected to the ground, because the data will be transported only one way to the display.
