LCD modules are very commonly utilized in most embedded projects, the rationale being its cheap price, availability and programmer friendly.
Most folks would have encounter these displays in our day to day life, either at PCO’s or calculators.
The appearance and therefore the pinouts have already been visualized above now allow us to get a touch technical.
16×2 LCD is known as so because; it's 16 Columns and a couple of Rows.
There are tons of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. but the foremost used one is that the 16×2 LCD.
So, it'll have (16×2=32) 32 characters in total and every character are going to be made from 5×8 Pixel Dots.
We know that every character has (5×8=40) 40 Pixels and for 32 Characters we'll have (32×40) 1280 Pixels. Further, the LCD should even be instructed about the Position of the Pixels.
Hence it'll be a busy task to handle everything with the assistance of MCU, hence an Interface IC like HD44780is used, which is mounted on the backside of the LCD Module itself.
The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen.
This high quality 16 character by 2 line intelligent display module, with back lighting, Works with almost any microcontroller. This is a popular 16x2 lcd display.
It is supported the hd44870 display controller hence it's easy to interface with most micro controllers.
It works of 3.3v and has a green back light which can be switched on and off as desired. The contrast of the screen also can be controlled by varying the voltage at the contrast control pin (pin 3).
