QUE STION 1 For a 10 bits ADC by Successive Approximation, how many comparisons are needed for the ADC to complete? a. It depends on the analogue value O b. 10 c. 1024 o d. 9 QUESTION 2 One of the following statements on ADC in the ARM processor is incorrect. Which one? a. The four bits configuration for a ADC input pin are 0000 o b. Configure RCC_APB2ENR register to enable the ADC clock c. One pin from GPIO port D can be configured as an ADC input pin. o d. The ARM can take maximally 18 ADC inputs including the two internal channels QUESTION 3 The following codes are supposed to configure the ADC. ADC1->CR2 (7

Solution

Question(1):

Answer:B

becuase:Microcontrollers commonly use 8, 10, 12, or 16 bit ADCs, our micro controller uses an 8 or 10 bit ADC.
