Microprocessor interfacing

14) To make the full scale Vout of the ADC to correspond directly to the temperature as monitored by the sensor, you need to set 15) In personal computers, how many clocks are used to synchronise activities of all peripheral chips connected to the CPU? 16)A stepper motor undertakes 30 revolutions per minute and 50 steps per revolutions. Compute the steps per second 17) What does it mean when it is said that a given sensor has a linear output 18) What is the difference between Vce and Vee pins on the LCD? SECTION B 1) In the ADC0848, what should be the Vref value if we want a step of 5mV? 2) If a motor takes 90 steps to make a revolution, what is the step angle for this motor? 3) With V 1.28V, find the Vin for the following output: d7 d6 d5 d4 d3 d2 di do 11111111 4) For an 8-bit ADC0848 chip, find the step size for each of the following Vrer. (a) Vref 1.28V (b) Vref 1 V. (c) VI 1.9V ref 5) In the ADC0848 (8-bit ADC), what should be the Vref value if we want a step size of20 mV
