Question 1 An accelerometer is interfaced to a RX83N microcontroller as on the figure 1.1. PE2 PES PEA Accelerometer RX63N Foure 01.: Nerece to accelerometer 1. Which ADC and channels is the accelerometer interfaced to? (6 marks) On the RXB3N, the ADC can be setup in single channel mode, continuous scan, and single scan mode. 2. We want a sampling rate of 500 Hz on the 3 channels for an indefinite amount of time. Which mode would be the most appropriate and why? (5 marks) 3. List the different ADC registers that need to be configured 17 marks) 4. Configure the ADC registers listed in 01.3 so it has the folosing functionalites. 500Hz sampling rate Mode identified in Q12 Interrupt enabled Triggered by software Data is flush right ADC operating clock should be 6MHz [10 marks) 5. Calculate the resolution of a 10-bit ADC operating between 0 and 5V. Show your calculation (5 marks)
