R&D Freelancer Scrapbook

This is my on-line scrapbook and/or blog.
I use it to collect information and make notes on everything I find useful and interesting.
The main focus will be Embedded Systems Architecture.
This means mainly embedded electronics, embedded software, mechanics and open source hardware and software.

Due to the limited amount of time I have, to moderate comments I have disabled this option, however I do want to hear from you if you have remarks, suggestions, language improvements and/or questions. Please use the contact form.

Thanks, Robert.

  • Server; Device that has the data

My Real Time Scheduler a RTOS study part 1

All of which I’m not going to repeat.
