Hello friends, I hope you all are doing great. Today, I am going to share the STM32 Blue Pill Library for Proteus . The Blue Pill is the board that brought STM32 to hobbyists: an STM32F103C8T6 - an ARM Cortex-M3 at 72 MHz with 64 KB of flash and 20 KB of RAM - on a small blue board that costs less than an Arduino Nano. With this library it runs your STM32 Arduino sketch in Proteus 8.5, with the STM32 core's pin names.
