This application note describes two different methods for driving liquid crystal displays (LCD) with any standard STM8S20xxx microcontroller (MCU), without any specific on-chip LCD driver hardware: ● the first method uses the timer 2 channel resource and also allows LCD contrast control through software ● the second method uses the Auto-wakeup mode only
This document details two software-based methods for driving liquid crystal displays (LCD) using standard STM8S20xxx microcontrollers without specific on-chip hardware. The first method utilizes Timer 2 resources to allow for contrast control via software, while the second relies solely on Auto-wakeup mode.
It describes methods for driving LCDs with any standard STM8S20xxx microcontroller.
Yes, the first method uses Timer 2 and allows LCD contrast control through software.
The second method uses the Auto-wakeup mode only.
