Management
The display can be controlled in the following modes:
- 8-bit without the reading of the busy flag - to transmit, the eight data bus lines and two control lines (RS, E - RW connected to ground) are required.
- 8-bit with the reading of the busy flag - to transmit, the eight data bus lines and three control lines (RS, E, RW) are required.
- 4-bit with reading of the busy flag - to transmit, the four lines of the data bus and three control lines(RS, E, RW) are required.
- 4-bit without reading of the busy flag - to transmit, the four lines of data bus and two control lines (RS, E - RW connected to ground) are required.
The most frequently selected method of communication is the 4-bit mode without reading of the busy flag. Sending a half-byte allows you to save valuable leads I/O of microcontroller - only four data lines (in 8-bit eight of them are busy) are used. Lack of the reading of the busy flag introduces the need to use software delays but allows you to save another line - R/W. Pin can be connected on a permanent basis to the masses because the data will be delivered only in one direction, to display.
