Dimensions and pinout description.
Display pinout description
Thealphanumeric 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 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 data will be transported only one way - to the display.
The versatility of the display allows to choose also the most suitable way of control.
The display - rear view.
