Announcements:

The final marks are available here sorted according to the last four digits of the student ID. Please note that the grades are unofficial and may be subject to some further adjustment at the discretion of the Faculty of Engineering. Carefully check the marks to make sure that there have been no recording errors. If you find any errors, please contact Dr. Cockburn by e-mail.
Unofficial lab grades have been posted. Please verify and notify the lab instructor (email: nem) of any errors that you find. The marks are posted by the least significant digits of your student ID, so if your student ID is 0123456 then your marks will be listed under 3456. Have a restful and fun holiday and I'll be seeing some of you in the New Year. Nancy. [December 24, 2004]
Lab #4 has been marked. Come and pick up your report from the lab instructor's office (W2-054). The reports will be available for pick up until January 24th. At that point, any remaining reports will be shredded. A synopsis of the lab report marks for all sections will be posted as soon as it is ready. [December 23, 2004]
Return your kits (breadboard and DB-9 cable) today from 2-5 PM, tomorrow 2-5 PM or Monday 2-5 PM in the lab.

Inconsistencies between the schematic and the 2nd and 3rd paragraphs in the background section of Lab #4 have been corrected. Consult the lab #4 web page for the updated version of the lab background. No changes to any of the exercises were made. [November 24, 2004]
Many of you have questions regarding the testing section of the recently returned lab 2 report. The testing section incorporated both the testing and hardware sections of the report. The maximum score for the testing section was 20 and the maximum score for the hardware section was 10 for a total of 30 as indicated on the marking sheet. Hopefully, this will clear up any questions you have. If not, see the lab instructor for further clarification. [November 24, 2004]

! Due to Remembrance Day (November 11) demo and report due dates for lab #2 have been reduced by one day.
* Due to Remembrance Day (November 11) , students in lab section D4 can choose to attend another lab section subject to space limitations. However, they are encouraged to attend a rescheduled lab section D4 on Friday, November 5 if at all possible. The report and demo deadline for students in lab section D4 will be 14 days after their rescheduled lab session. This is the same rule used to determine the report due date for the other three lab sections.
+ Due to the Remembrance Day holiday, demo due dates coincide with the report due dates for lab #3 only. Note that due to various issues, demo due dates and report due dates now coincide for all labs.
^ University regulations do not allow course work deadlines to extend beyond the end of the semester. Consequently, demo and report due dates have been reduced by one day.

Code of Student Behaviour:

It is the student's responsibility to be familiar with, and to adhere to, the terms of the University of Alberta's Code of Student Behaviour. Included in the Code are descriptions of unacceptable behaviour for students attending the University, the sanctions for the commission of academic offences, and explanations of the complete discipline and appeal procedures. In particular, please note the definitions of plagiarism in section 30.3.2(1), of cheating in section 30.3.2(2), of misrepresentation of facts in section 30.3.6(4), and of participation in an offence in section 30.3.6(5). For example, cheating includes the submitting of the words, ideas, images, or data (including computer programs) of another person as the student's own in any academic writing, essay, thesis, research project or assignment in a course or program of study. Penalties for academic offences range from a written reprimand up to expulsion from the University.

Supplementary Reference Materials:

Please do not feel obligated to buy copies of any of these books. They are not required for the course, but you might find some of these titles useful to supplement the lecture and laboratory material. Limited numbers of the book on MicroC/OS-II by Jean Labrosse are available in the University bookstore. This book would be a useful reference for the laboratory exercises, and might be useful later on for project courses.
