ECE177课程简介
Lab 7a: Week of October 11 Breadboard wiring is here. Hex code for testing is here.
FYI, datasheet for the AVR is here.
Instructions for setting up the programmer are here.
Lab 7b: Week of October 18 – Lab 7 assignment is here. and starter code is here. Note: For pre-lab work the CodeLab problems associated with this lab before coming to lab.
To use the LCD you will need lcd.h and liblcd.a and link them with your code (may need to “Save link as…”)
Info on compiling and programming is here for Windows users and here for Mac users
Lab 8: Week of October 25 – Lab 8 assignment is here. and starter code is here.
Prerequisites
Note: For pre-lab work the CodeLab problems associated with this lab before coming to lab.
Optional: Here is a test program for testing your getkey() routine before putting it into CodeLab
Optional: Here is a hex code for testing your keypad and wiring
Lab 9: Week of November 1 – Lab 9 assignment is here. and starter code is here.
Note: For pre-lab work the CodeLab problems associated with this lab before coming to lab.
Here are some test sequences:
Lab 10: Week of November 8 – Lab 10 assignment is here. and starter code is here.
Note: For pre-lab work the CodeLab problems associated with this lab before coming to lab. Read “Pre-lab” section on lab sheet first.
Lab 11: Week of November 15 – Lab 11 assignment is here. and starter code is here.
Note: For pre-lab write what you can before coming to lab.
ECE177 introduction to programming HELP（EXAM HELP， ONLINE TUTOR）
1) For each of the following expressions add a pair of parenthesis for each operator to indicate the order of precedence. Then evaluate the expression in a series of steps, one line for each operation. The first expression is done for you as an example:
14
(h)
(i) $\quad$ (j)
$(\mathrm{k})$
$! 0\left|6 \& 3^{\wedge} 6 \quad 9 \% 7<<5-3\right| 1 \quad 3 !=2 \& \& 4<=5^{\wedge} 4 \quad 7-2==5 \quad ? 3: 2+2$
(h)
Parentheses: None
Evaluation: 14
(i)
Parentheses: None
Evaluation: Error (missing operand)
(j)
Parentheses: None
Evaluation: Error (missing operand)
(k)
Parentheses: None
Evaluation: Error (missing operand)
$! 0\left|6 & 3^{\wedge} 6 \quad 9 % 7<<5-3\right| 1 \quad 3 !=2 & & 4<=5^{\wedge} 4 \quad 7-2==5 \quad ? 3: 2+2$
Parentheses: $!(0)|((6& (3^6))\quad ((9%7)<<(5-3)))| (1) \quad (3!=2) && (4<=(5^4)) \quad (7-2)==5 \quad ?3:(2+2)$
Evaluation:
$3^6 = 729$
$6&729 = 0$
$9%7 = 2$
$5-3 = 2$
$2<<2 = 8$
$!(0)|0|1 \quad 3!=2 && 4<=625 \quad 7-2==5 \quad ?3:4$
$1|1 \quad 0 \quad 1 \quad 3$
Final result: $3$
2) Evaluate each of the following expressions, and give the value of any variable used in the expression after the expression is executed. For each instruction assume the variables are given the following values.
$$
\begin{aligned}
& x=3 \
& y=5 \
& z=7
\end{aligned}
$$
If a variable changes in one expression, assume it is reset to its original value before performing any later expressions (i.e., $\mathrm{x}$ is 3 at the beginning of each expression). The first is done as an example. Show the steps used to get your result.
(a) $y=x+2z$
- Substitution: $y=3+2\times 7$
- Evaluation: $y=17$
- Value of variables after execution: $x=3$, $y=17$, $z=7$
(b) $x=\frac{z}{y}+z$
- Substitution: $x=\frac{7}{5}+7$
- Evaluation: $x=\frac{42}{5}$
- Value of variables after execution: $x=\frac{42}{5}$, $y=5$, $z=7$
(c) $y=x^{z-y}$
- Substitution: $y=3^{7-5}$
- Evaluation: $y=9$
- Value of variables after execution: $x=3$, $y=9$, $z=7$
(d) $z=x+y+(z-x-y)$
- Substitution: $z=3+5+(7-3-5)$
- Evaluation: $z=7$
- Value of variables after execution: $x=3$, $y=5$, $z=7$
(e) $x=2y+z-1$
- Substitution: $x=2\times 5+7-1$
- Evaluation: $x=16$
- Value of variables after execution: $x=16$, $y=5$, $z=7$
