======Class Stats======
  * [[/haas/fall2019/c4eng/projects/status|status]] (coming at some point)

======URLs======

  * [[http://publications.gbdirect.co.uk/c_book/|The C Book, online C book]]
    * [[http://publications.gbdirect.co.uk/c_book/thecbook.pdf|PDF of above]]
  * [[/_media/haas/printf.pdf|printf PDF]]
======Week 7======

  * continued exposure utilizing loops in problem solving
  * possible integration of arrays to further streamline process
  * binary counter in incrementing and decrementing fashion

======Week 6======

=====colorled=====
  * multi-coloured (RGB) LED, using PWM to set different intensities of Red, Green, and Blue (100 different levels of adjustment for each)
  * In the **examples** subdirectory, there is now a **colorled** entry with a sample program.

Here's a diagram of the circuit to assemble:

{{:haas:fall2019:c4eng:rgbled.png?400|colorled diagram}}

====Lab Project====
Once you have the circuit wired up and verify operation with the sample program, I'd like you to write a new program that:

  * starts at "nothing" (no light)
  * going from nothing and gradually (10 steps) to full intensity:
    * nothing to red, then reset, and go:
    * nothing to green, then reset, and go:
    * nothing to blue, then reset, and go:
    * nothing to purple, then reset, and go:
    * nothing to red+green, then reset, and go:
    * nothing to green+blue, then reset, and go:
    * nothing to white (red+green+blue).

===Hints===
  * Figure out how to set the level of ONE color to its maximum value
  * How would you adjust these across a given range (0-99)
  * One thing at a time: worry about JUST red first, then JUST green.

===Copying sample file from lab46 to your pi===
<cli>
lab46:~$ cd /var/public/fall2019/c4eng/examples/colorled
lab46:/var/public/fall2019/c4eng/examples/colorled$ ls
colorled.c
lab46:/var/public/fall2019/c4eng/examples/colorled$ scp colorled.c pi@10.80.2.X:
</cli>

On the scp line, do NOT forget the trailing colon. It is important.

===Copying a file from the pi to lab46===
<cli>
pi@raspberrypi:~$ ls
program.c
pi@raspberrypi:~$ scp program.c user@lab46:
</cli>

===Submit===
When done, submit your source code on lab46 for the project **epf0** 
======Week 5======
=====potled=====
  * 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:

{{:haas:fall2019:c4eng:potled.png?400|potled diagram}}

=====buzzer=====
  * 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:

{{:haas:fall2019:c4eng:buzzer.png?400|buzzer diagram}}

======Week 4======

=====buttonled=====
  * 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.

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

{{:haas:fall2019:c4eng:buttonled.png?400|buttonled diagram}}

======Week 3======
  * I have put together a [[/haas/fall2019/c4eng/projects/sof0info|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.
======Week 2======
  * 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 [[/haas/fall2019/c4eng/projects/dtr0info|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 [[/haas/fall2019/c4eng/projects/pctXinfo|document to provide some additional background information]].

======Week 1======
  * 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 **{{:haas:ufbm.pdf|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**
