AIM- To find the true reading of the temperature in degree Celsius. STATEMENT- In a temperature control system, input received by sensor is 57 degree C. From the calibration of temperature sensor, it is already known that the sensor shows error of -8 degree Celsius. How will you obtain the true reading in your data record?

How does the application software resume normal functioning when the interrupt service is completed?
Suppose you are using SysTick in a busy-waiting method to periodically read a sensor value every 0.25 ms (i.e., initially, you are not using interrupts, but rather you are using a while busy-wait loop). a) Suppose you measured the microcontroller current and found it to be 200mA. If the microcontroller core voltage is 3.3V, what would be the microcontroller power consumption during the busy-waiting for the PWM method? Answer format: floating-point with at least two decimal places: Answer Watts. b) Suppose you were not happy with the power consumption of the busy-waiting method. Therefore, you decided to implement periodic interrupt with SysTick. You write a SysTick ISR handler consisting of 400 instructions long. Suppose the microcontroller CPI average is 1.5. How many clock cycles does it take to execute your ISR handler? Answer format: integer Answer c) How long doe it take to execute your ISR in microseconds if SysTick and the microcontroller are running at 48 MHz? Answer μs c)…
