Pinout description of the display

Alphanumeric display has 12 pins, which are not marked on the board. Each of them corresponds in turn to:

  • 1 - VSS - system ground
  • 2 - VDD - 5V power supply
  • 3 - V0 - contrast
  • 4 - RS - select display instruction register (low state) or data register (high state)
  • 5 - R/W - read (low state) / write (high state)
  • 6 - E - unlocking the display
  • 7...14 - DB0...DB7 - data bus
  • 15 - LEDA - backlight power supply 5 V
  • 16 - LEDK - backlight system common ground

Controlling 2x16 LCD module

The display from justPi can be controlled in four modes:

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

The most often chosen communication mode is the 4-bit mode without reading the busy flag. Sending half a byte saves valuable I/O pins of microcontroller - only four data lines are used (in 8-bit mode eight of them are occupied). Not reading the busy flag makes it necessary to use software delays, but saves another line - R/W. This pin can be permanently connected to ground, because the data will be transported only one way - to the display.
