ECE 110 is a required course for all students planning to earn a major in Electrical and Computer Engineering or Biomedical Engineering at Duke University. It may also be taken to satisfy the cross-disciplinary requirement for the Civil and Environmental Engineering degree. This page is meant to provide answers to general questions about the course, not necessarily specific questions about content. There is also a Category:ECE 110 that will list all pages relevant to ECE 110. Note at the bottom of this page that it is a member of that category. This is the page for Spring, 2018.

Connecting the Parallax Digital Trainer to the BOE Shield

This requires two male-to-male 3-header cables.

  • The first cable will go from channels GND/13/12 on the BOE Shield to channels GND/P0/P1 on the PDT. The black wire should be on GND; for the BOE Shield, that is the second-to-leftmost pin on the top bus while for the PDT, that is the fourth pin from the top on the left of the socket.
  • The second cable will go from channels 2/3/4 on the BOE Shield to P2/P3/P4 on the PDT. The black wire should be on pin 2 of the BOE Shield and in the sixth-from-the-bottom socket on the PDT. The white wire should be on pin 4 of the BOE Shield and in the fourth-from-the-bottom socket on the PDT.
Note that the left header here is connected the the header on the right in the PDT picture

Questions

Post your questions by editing the discussion page of this article. Edit the page, then scroll to the bottom and add a question by putting in the characters *{{Q}}, followed by your question and finally your signature (with four tildes, i.e. ~~~~). Using the {{Q}} will automatically put the page in the category of pages with questions - other editors hoping to help out can then go to that category page to see where the questions are. See the page for Template:Q for details and examples.
