3.3.7 PWM DAC

The LaunchPad provides up to four PWM DAC signals at the BoosterPack headers using GPIO0 (BP pin 40) and GPIO1 (BP pin 39) on site 1 and GPIO12 (BP pin 80) and GPIO13 (BP pin 79) on site 2. The intended purpose of the PWM DAC signals is to utilize PWMs of the F280013x device as digitial-to-analog converters (DAC). This method involves low-pass filtering of the PWM signal to remove the high-frequency components and ideally leave only the DC component. See Using PWM as a DAC for more information.

By default, the RC filter is not populated. Instead, a 0-ohm resistor is populated and the capacitor is left unpopulated.
