In-lab Tasks:

1. Build the RC circuit and attach it's input to pin PA4.
2. Modify the program you wrote in the preceding lab so it accepts a 6-bit integer representing the requested output value of your DAC, outputs a 3-bit version of this request to the 7-segment LED display. Your program should set the PWM signal's period equal to the period ($T$) you determined in task 3 of the pre-lab tasks.
3. Use a DMM (set to measure DC voltages) to measure the voltage output by your DAC circuit for at least 32 different commanded voltages.
4. Use the oscilloscope to measure the steady state voltage and value of the RC circuit's response for at least 32 different commanded voltages. Please note that it may be difficult to stably trigger the scope directly from the RC circuit's output. It is recommended that you use channel 1 to display the RC circuit's output and that you use channel 2 to display the PWM signal. Be sure to trigger the scope from channel 2 as the PWM signal provides a more reliable triggering signal.
5. Description of what happened during in-lab task.
