• The C Book, online C book
  • PDF of above

• potentiometer + LED
  • potled.c now placed in examples subdirectory. It has been enhanced with further comments.
  • NOTE: In order to run this program, we will need to enable I2C support on the pi (a one-time thing, then we're set).

Here's a diagram of the parts needed and circuit to assemble:

• button + buzzer
  • buzzer.c now placed in examples subdirectory. It has been enhanced with further comments.
  • NOTE: This program is functionally similar to our buttonled.c program we worked on earlier.

Here's a diagram of the parts needed and circuit to assemble:

• The “buttonled” programs we wrote in class have been added underneath the examples subdirectory in the c4eng public directory, including additional comments.
  • buttonled.c - basic program; press button to light up LED
  • buttonled2.c - LED will appear to “blink” for the duration of the button press
• Please make sure you are reading through the chapter on if statements/selection structures/conditional statements.

• I have put together a sof0 hints page, that may have some useful information you want to check out if you are having trouble getting started.
• Please make sure you are reading through the chapter on variables and arithmetic operations.

• After getting through the typically chaotic first week activities, the dust is starting to settle; questions are being asked, things are being figured out.
• We went through the “Hello, World!” C program, and then moved onto the next programming project, dtr0.
• There are likely some questions on a number of aspects related to dtr0. I am endeavouring to put together a document to provide some additional background information.
• The pct1 project is also in progress. For some of the more technical aspects of the project, I have also put together a document to provide some additional background information.

• Welcome! I've wrapped some initial activities into the cci0 and dtr0 projects, that I'd like you to perform by the given deadlines (by 11:59:59pm / 23:59:59 on posted day).
• If you've never used a UNIX system before, I'd recommend reading UNIX for the Beginning Mage; it is short, and likely one of the best reads you'll ever have.
• Get familiar with how to log onto Lab46, and once on:
  • change to your src/ subdirectory
  • create/edit .c files (such as hello.c), and learn how to save/exit
  • compile the C program (.c file(s)) into an executable with gcc
  • execute the compiled C program (the executable) by specifying a path: ./program_name
