GETTING STARTED WITH PICAXE MICROCONTROLLERS: PART 3

摘要

Last month, we interfaced the 18X with a Hitachi HD44780-based LCD display. Now we are ready to add a 12- or 16-key matrix keyboard and a piezo beeper to complete our I/O terminal. For those projects that do not require user input (i.e., they only need the LCD for program output), we will also discuss a simplified version of our terminal program that will provide just the "serialized" LCD for output, as we conclude this series.
