HITACHI HD44780 LCD DISPLAY DRIVER
The 8-bit interface is conceptually simpler and is very convenient if you attach an 8-bit shift register to the display. The most important pins are.
LCD display compatible with Hitachi HD driver
If the next received character is ' ', we then assume that there are no more characters and we exit hitachi hd44780 lcd display loop. This is just an example, if you expect a series of words then your logic will have to be a bit more complex, such as looping through the entire line, an easy fix. Since the cursor position is being tracked by the AC, Address Counter, our cursor is already sitting at a location after the read text. All we have to do is read the characters from the array and display them one at a time back to the display.
This image is rather boring. This function also sets up the hd interface to use 4 bit operation instead of 8 bit operation.
Check the specification for details. The hd can accept both commands and data. By changing some bits in the MPU interface you can either send data or instructions.
So in this next example, if we un-comment hitachi hd44780 lcd display of the two lines we can display a cursor and or blink the cursor. In the next page this device is used to reduce the number of pins from the Arduino.
