General Purpose Input Output (GPIO)
The very first “Hello World” project that we do with every new embedded device is a simple LED
blinking program. Here we do the same. We will be basically testing both input and output function
by making a variable flash rate blinking LED. Check the schematic of the Disco board. Check the pins
with which the on-board LED and the push button are connected.
You can also use the STM8CubeMX in board selector mode for this too.
