CMSE423 Sample Final Questions 1 CMSE423 Sample Final Questions For the continuous time xcos simulation of the yogurtmaker project this diagram contains both the physical and cyber parts of the overall system. Write the components of the physical system: Q2- Yogurtmaker needs a WiFi router, and its dashboard appears on the users intelligent phone or tablet. Are WiFi router and dashboard a physical part, or a cyber part? Are user's phone and WiFi router part of the embedded system? Q3- The new UART parser of the yogurtmaker needs to parse the strings to act on ' ', ' 0 ' ... '9', 'S', ' X ', and ' m ' to set autom FALSE and TRUE, plus to set tmin to an integer value, such as tmin-85 minutes using the UART string " 85m ". Complete the following State-Machine Diagram for adding new command. Q4- Complete the flow-code of the parser procedure that implements the state machine given at question-3. Ascii codes of ' ', '0'...'9', 'S', ' X ', and 'm' are 32,4857,83,88, and 109. Q5- i-What shall be the type of port at the setup flow if IO11 is connected to a button switch, and the other terminal of switch is connected to ground? ii- What is the name of the procedure that reads the state of the IOl 1 ? Q6- LM35 measures temperature in the 070C range with 0.2C precision. Calculate the dynamic range of the LM35 sensor in deciBels. Q7- LM35 output voltage Vo =0.01T is quantized by 10 -bit Arduino ADC using 1.1 Volt reference. i- What is the quantization error in units of Celsius with this ADC. ii- What is the quantization dynamic range of ADC when measuring 070C range of sensor? Q8- AVR 328 processor does not have an internal clock oscillator. It can be used with a quartz crystal, ceramic resonator, or an RC clock. i- Which of these three oscillators are the most expensive oscillator
