Application note
How to use the STM8AL3Lxx, STM8L152xx
and STM8L162xx LCD controllers
Introduction
This application note describes techniques for connecting the LCD controller available in the
medium density STM8AL3Lxx devices, medium density STM8L152xx devices, medium+
density STM8L152xx devices, and high density STM8L152xx/STM8L162xx devices, to
liquid crystal displays (LCD), for driving alphanumeric characters and for converting ASCII
characters to LCD segment control codes.
It explains how to select the LCD glass best suited for your application, and how to configure
the LCD controller to take into account key parameters such as contrast, power
consumption, number of used pixels, operating frequency range, and blinking.
A brief description of the LCD segment drive firmware embedded on the STM8L1526-EVAL
and STM8L1528-EVAL evaluation boards is also provided.
For more information, please refer to the STM8L05xx, STM8L15xx, STM8L162x,
STM8AL31xx and STM8AL3Lxx microcontroller family reference manual (RM0031).
