Welcome to my blog! My name is Petr Hapal and I'm trying to split my time in beeing a professional hardware and firmware developer, husband and father of two great sons. I'm heavily interested in electronics, programming, aquaristics and I've started to play table tennis in the middle of 2012.

Here on this web you will find several notes which I've found useful or interesting during my developement. I would also like to publish first steps in microcontroller programming especially for newbies. I know that the first steps in microcontroller programming are the hardest ones.

I'd like to post everything multilingual - English and Czech. The reason is that I found it as some kind of benefit especially for young hobbists here in Czech Republic.

I've decided to post all source codes here on this web under BSD (if not noted otherwise) - see Terms of use.

If you have any questions please feel free to contact me. But please be tolerant in my response time. The day has only 24 hours which is not sufficient for me to fulfill all requests and private tasks.
