Programming: LCD Code for the Sending a Command Function

To send a command to the LCD, the data port connected to the LCD must have the data on that bus and the data will remain on that bus while the next commands are invoked: - The control port of the LCD should a the R/W line low to write. - The register select (RS) of the LCD needs to be set low for command mode. - The enable needs to be set high and wait and then set low. During this time, the LCD gets the information from the port of the command and port of the data lines. Now the command can be zeroed.
