Alphanumerical Lcd - STMicroelectronics STM8 Manual

Alphanumerical LCD

Alphanumerical displays are the most common and basic form of displays after seven segments and
LED displays. They are useful for projecting multiple data quickly in ways that are otherwise difficult
with other kinds of displays.
To interface a LCD with a STM8 micro, we need LCD library. The STM8 SPL does not have a library for
such displays and we need to code it on our own. Interfacing a LCDs are not difficult tasks as no special
hardware is required to drive LCDs other than GPIOs. However, there are some tasks needed in the
software end. We need to include the library files. The process of library inclusion is discussed in the
later part of this article as it needs some special attentions. The example I'm sharing here uses 6 GPIO
pins from GPIOC. The read-write (R/W) pin of the LCD is connected to ground. The layout is as shown
below.
