Emulating Raspberry Pi on Linux
Raspberry Pi has gained a lot of fame over the past years since it’s introduction. Being dirt cheap while powerful enough to run your home multimedia center is the key selling point of Raspberry Pi. But when it comes to…
Setting up development and programming for STM8 on Linux
STM8 Series of micro-controllers by ST Microelectronics are dirt cheap and powerful at the same time. Their processing power is nothing short as of Arduino, while at the same time their power consumption is much less. These properties makes STM8…
Getting started with STM8 Development – Part 2 – Input handling
Now that you learned how to configure one of the pins of a STM8 micro-controller as output to blink a LED in the first part of STM8 basic tutorials, it is time to learn how to configure pins as input,…
Getting started with STM8 Development – Part 1 – Blinking a LED
Usually the first step toward learning development on a micro-controller is simply blinking a LED, as an analog to “Hello, world!” example used on PC programming languages. This time we will have a look into how to start programming and development…
