The practice is obligatory

Attending the practical lessons is obligatory.

Not possible to attend the practice? contact dhr Stokkink

Failing to attend more then 2 practical lessons, there will be no grade!

During the practical lessons the logbook will be assessed

16-08-11 5

Assessment

The logbook will be looked at as an assessment

Home-orders will be assessed sufficient or insufficient.

All home-orders must be sufficient in the end.

16-08-11 6

Responsibilities

The student is responsible for the hard-en software, there are more groups who must use it.

Defects must be reported immediately.

Practical

Each week an introductory assignment At the beginning of the week the home

assignment must be shown on the test board. Is must be through a flowchart and the program in your logbook.

Software is free at www.microchip.com en
