(a) Find the resolution for a microcontroller anadlog to digital controller (ADC), if the accuracy is 54.6mV and the ADC is powered using 7 volts [5 marks] (b) If the ATmega16 microcontroller is using a clock frequency of 3 MHz, what are the fastest and slowest frequencies for the ADC unit? (5 marks] (c) A microcontroller is interfaced with an analog sensor at pin 2. Using figure Q4c() and Tables Q4c(i) and Q4c(ii),write a C code that will correctly configure...
How many channels of does the ATD have? How many bits does each channel data register have? What port pins are used to access the ATD channels?
IN MBED MICROCONTROLLER: What does the term bistable mean? How many bistables would you expect to find in the mbed’s SRAM? What are the fundamental differences between SRAM and DRAM type memory?
Question 3: In class we showed how to simply light up an LED on our Teensy microcontroller. In fact, the procedure is similar for all processors including a simpler 8-bit ATmega 328P (a.k.a Arduino Uno) For purposes of this exercise, let's say that the ATmega328 has 4 regular GPIO ports; A, B, C, and D, each with 8 pins. Every GPIO port has three registers (outlined in table below) PORTX: used to write output on a pin on port X...

Q3. Suppose a language containing five letters: A, B, C, D, E (5%) (b) How many four-letter words can you form if each letter appears only once in each word? (5%) (c) What is the probability that a three-letter word (with each letter appearing only once) con (a) How many three-letter words can you form in this language? tains E? (5%)
25. It is my contention that the most important input sensor is the switch/pushbutton. How can you avoid having to add an extemal pull-up resistor when a switch is connected to a digital pin? 26. Some of the pins have the tilde() symbol written before their number. What does this mean? 27. The Arduino pins A0 through AS are written on the board as ANALOG IN and can read OV to 5V). The analogRead(pin) function reads the voltages as raw...
2. Given the following setup for GPIO (fill in all the blanks, refer to pages 1-4) GPIOB_MODER 0x10000 //GPIOB_OTYPER is not needed as its default value is zero GPIOB_OSPEEDRI=0x3000; GPIOBPUPDRI= 0x80; - a. Which port is being initialized? Port b. Describe the important features from the initialization for pin 3 Ifor example input, output, alternate function, analog, pull up, pull down, push/pull, open drain out, speed, etc.). Px3 is initialized to be c. Which pin is being initialized as an...
