Application note
RS232 communications with a terminal
using the STM8S-DISCOVERY
Application overview
This application note describes how to control the STM8S-DISCOVERY from a terminal
window running on a PC which is connected to the STM8S105C6T6 microcontroller UART
through an RS232 cable.
After adding the required components to the board and downloading the application
software, you will be able to use a terminal to manage STM8S GPIOs and TIM3 timer, and
to configure the beeper output.
