John, For your first question, the FAST algorithm accounts for and requires a hardware voltage filter, implemented by C9, C10, C11. Without those, it will not operate correctly. For the second question, note that the voltage offset value of 0.5 does NOT represent 0.5V, but rather a 0.5 scale factor. In other words: If the ADC has a reading of (ADC_MAX_RANGE) / 2, then the voltage being measured is (0.5 * VOLTAGE_MAX_READING) For a 12-bit ADC and a maximum voltage reading of, just for an example, 100V, an ADC reading of 2048 would be equivalent to 0.5 * 100 = 50V For the final question regarding having the motor connected in lab 1, I have accidently done so in the past myself, but I haven't experienced any damage to the motor from this.
