Hi there,
I'm an electronics/software engineer with experience C/C++.
I've experience in writing application for Raspberry Pi, incl. 24/7 working apps.
One of my last project was a professional ski resort turnstile based on Raspberry Pi (using: serial port, rtc, tcp/ip, local SQLite database, SDL 2D graphic).
In my projects I've been working with any things that You need and I have some own libraries.
Best regards
Wojciech Bogal
