PWM is routine that is backwards compatible with the BASIC stamp, and
is a software driven routine. The HWPWM uses the hardware PWM
circuitry of the LPC2103 to generate an infinite pulse stream. This
output is a square wave, but it can be filtered by something like a
MAX280, though this would require custom setup of the PWM hardware to
generate the 2 different cycle PWMs.

Both PWM and HWPWM can be filtered to generate a D/A converter
