LCD 1602 I2C with STM8S103F3P6 using ST Visual develop IDE

Prerequisites

This project assumes you have already installed ST Visual develop IDE and Cosmic Compiler. You need to have previously done a basic blink sketch with STM8S103F3P6 using STVD. I have made a complete video from installing to LED blink program. You can watch it by clicking this link. https://www.youtube.com/watch?v=iFiBfx9vCqo
