Pinout description.
Display pinout description
The alphanumeric display has 12 pins that are not labeled on the board. Each pin corresponds to:
- 1 - VSS - system ground
- 2 - VDD - 5V power supply
- 3 - V0 - contrast
- 4 - RS - selection of 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 - ground of the backlight system
2x16 LCD module control
The justPi display can be controlled in four modes:
- 8-bit without reading the busy flag - eight data bus lines and two control lines (RS, E - RW connected to ground) are needed for transmission,
- 8-bit with busy flag reading - eight data bus lines and three control lines (RS, E, RW) are needed for transmission,
- 4-bit with busy flag reading - four data bus lines and three control lines (RS, E, RW) are needed for transmission,
- 4-bit without reading the busy flag - four data bus lines and two control lines (RS, E - RW connected to ground) are needed for transmission.
The most commonly chosen communication method is 4-bit mode without reading the busy flag. Sending half a byte saves valuable microcontroller I/O pins – only four data lines are used (in 8-bit mode, eight are occupied). Not reading the busy flag introduces software delays, but saves another line – R/W. This pin can be permanently connected to ground, as data will only be transmitted one way – to the display.

The LCD display has soldered connectors.
