ECE 4175 QUIZ 2-17-10 (1 of 2) High 110 SEVEN PROBLEMS Upper quarter 92 Open book, open notes Median 83 Lower quarter 65 I added 10 points to everyone’s grade. Low 37 1. Consider the schematic of Figure 3-2. When the LED on the Qwik&Low board is turned on, [10%] PORTDbits.RD4 = 0 b 0 0 0 0 0 0 0 1 2. Using the index value, i (already declared as an unsigned char variable), show a for loop that will use the TXascii macro to copy the characters that have just been sent to the Qwik&Low board’s LCD to [15%] QwikBug’s console window. You may assume that the UART has already been initialized with InitTX. for ( i=0 ; i<9 ; i++ ) // This will get nine values: i = 0,...,8 { TXascii(LCDSTRING[i]); } 3. One group in the lab, working on Project Five, found that when they ran their code to step the stepper motor, the stepper never took a single step. After thinking about what could be wrong, they wondered [10%] whether their high-priority interrupt service routine was ever being executed. Without changing their code, what might they have done to answer this question?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
