| 6| 4/05 | 4/12 | 4/26 | Read Chapter 7 through section 7.6.|
| | | | | Optional supplement on RS-232 |
| | | | | |
| | | | | Plot voltage vs. time for sending |
| | | | | this text: "Z#" (without the quote |
| | | | | marks) using RS-232. Assume |
| | | | | +/- 12V signal voltages, 53 kbaud, |
| | | | | eight data bits, and ene stop bit. |
| | | | | Be sure to label your axes |
| | | | | properly. An ASCII table can be |
| | | | | found in many places, e.g. |
| | | | | http://www.asciitable.com/ |

| 5| 3/08 | never | ---- | Read Ch. 6 |
| | | | | |
| | | | | Do 4.1 part a only, 4.2 part a only|
| | | | | Also do 6.7 part a only. |
| | | | | |
| | | | | As per classroom discussion on Tu |
| | | | | 3/29 the due date was changed from |
| | | | | 3/29 to 4/05. Also problem 6.7 was|
| | | | | modified by adding, "part a only." |
| | | | | |
| | | | | Note: there is no class to Tu 4/03 |
| | | | | because this is assessment day. |
| | | | | |
| | | | | On 4/05 this assignment was |
| | | | | entirely retracted. There are |
| | | | | typographic errors in some of the |
| | | | | problem statements and the |
| | | | | 68HC11 documentation is vague. |
|--+-------+-------+-------+------------------------------------|
| 4| 2/27 | 3/08 | 4/10 | Read Ch. 4 (omit 68HC12 and 9S12 |
| | | | | parts) |
| | | | | |
| | | | | Do these problems from Peatman's |
| | | | | text Design with Microcontrollers |
| | | | | 3.17, 3.19 |
|--+-------+-------+-------+------------------------------------|
| 3| 2/13 | 2/20 | 3/06 | Read Ch. 3 (omit 68HC12 parts) |
| | | | | Review all "Checkpoints" (Answers |
| | | | | are in the back of the text. Do |
| | | | | not turn these in. You need the |
| | | | | 68HC11 E family data book to answer|
| | | | | some of these checkpoint questions)|
| | | | | |
| | | | | Do 3.18 except modify it so that |
| | | | | a whole byte of data is read. |
| | | | | You may use assembly file |
| | | | | V3_18_TX.ASM as a starting point. |
| | | | | The comments in that file give |
| | | | | necessary information about |
| | | | | modifications to the problem |
| | | | | statement. You may also use I/O |
| | | | | file V3_18_TX.IO in your |
| | | | | simulation. Unfortunately the |
| | | | | TExaS simulator can only simulate |
| | | | | a total of 8 input bits in the |
| | | | | *.IO file and one of these must |
| | | | | be the "Status" signal. Thus in |
| | | | | the file given here PC0 is left |
| | | | | disconnected and only 7 bits of |
| | | | | data can be controlled by the |
| | | | | switches. |
| | | | | |
| | | | | 3.20 (not in text) How does the |
| | | | | STAF bit in the PIOC register get |
| | | | | set? Can you set it with software?|
| | | | | How do you clear STAF? |

| 2| 1/23 | 2/06 | 2/13 | Read Ch. 2 Sec. 2.1, 2.2, 2.3, |
| | | | | 2.5, 2.11.3 |
| | | | | |
| | | | | Do (on page 137) 2.1 |
| | | | | |
| | | | | You may use file "V2_1_TX.ASM" as |
| | | | | a starting point. Delete the |
| | | | | indicated comments and insert your |
| | | | | code. Simulate your results using |
| | | | | TExaS. Turn in "TheList" file and |
| | | | | a "TheLog" file which demonstrates |
| | | | | your working code. |
| | | | | |
| | | | | Note: As per discussion in class |
| | | | | on Th 1/25, the due date was |
| | | | | changed from 1/30 to 2/06. |
|--+-------+-------+-------+------------------------------------|
| 1| 1/16 | 1/23 | 1/25 | Read Chapter 1 |
| | | | | |

| | | | | 1.8, 1.10, 1.24, 1.25, 1.27, 1.28, |
| | | | | 1.30 |

Note 1) If a "#" follows the "returned" date, then the solution
key is posted on the cork board across the hall from room S233.
Note 2) Problems sets shown above with no "assigned" date are
tentative. More problems might be added, expected due dates
might change, but problems shown will eventually be assigned.
Note 3) If you are having difficulty reading the latest version
