Control

The display can be controlled in modes:

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

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