One of the following statements on DAC in the ARM is incorrect. Which one? In dual DAC channel mode, conversions could be done independently or simultaneously. The DACs in the ARM can be configured to do either 12 bits or 8 bits digital to analogue conversion. The DACs can be used to generate noise and triangular waveforms only. There are two DACs in the ARM processors. The following statements are on the DAC pins and output. Only one is correct. Which one? The reason that the DAC pins are first be configured to analogue inputs (AIN) is to avoid parasitic consumption. The maximum output of a DAC is 2 times V_ref The two DAC pins are PA14 and PA15. To carry a DAC conversion, you have to load the digital data to output holding register DORx in your program. The following operations are supposed to configure DAC 1. However one of them is really not necessary. Which one? DAC control register needs to be configured. PA4 must be configured as an analogue input. peripheral clock for DAC1, peripheral clock for AF. and peripheral clock for GPIOA are all need to be enabled. DAC software triger register has to be cleared, ie DAC rightarrow SWTRIGR = 0; The CMSIS core module core_cm3.h provides a set of inlined functions and helper functions. One of the following functions is not supported. Which one? Sets the priority for an interrupt IRQn. Enables an interrupt IRQn Resets the whole system including peripherals. Terminate an ongoing Interrupt IRQn In the startup file \"startup_stm32f10x_cl.s\", all the interrupt routine names are defined. Four are listed below. However one has a typo in it. Which one? USART3_IRQHandler USART1_IRQHandler ADC1_IRQHandler SysTick_Handler

Solution

Question 1) Ans:C

DAC is digital to analog converter ,whatever the digital sequence or wave form you gave it will convert that waveform to analog signal,so it not only generate noise or triangualr waveform ,any signal shape can be generated with the DAC
