Welcome to laros-education
Welcome to LarOs - eDucation
This web site is dedicated for all visitors and we'll give free tutorials about electronics and computer enginering.
The tutorials is exclusively to the Electronic projects such as MCS51 and AVR mirocontroller and related products (both hardware and software). This includes the traditional 8052, 8051, 8032, and 8031 along with more modern derivatives such as the Atmel AT89S51,AT89S52,AT89S53,AT89S8252, AVR ( AT90S series ) and many derivatives by Silicon Laboratories, Philips, and many others.
We have a tutorial section for the programmer or student that is just learning about the MCS-51 and AVR microcontroller. We have a reference section for the proficient developer who just needs to access some quick reference information.
Please spread the word about this site to friends and coworkers. Feel free to link to it on your web pages. If you have code or literature that you'd like to contribute to the site please contact us--we're interested in any and all material that we can get our hands on to pass on to other users of this site.
