Ramp Pulse Generator

This program produces a ramp, slow ramp, level or triangular pulse on po.

Select the desired output by un-commenting the desired function call in main. Produce negative pulses by reversing the ramp calls in pulse: 

	rcall rampup
	rcall rampdown
A neat trick is to pool the outputs of two pulse generators, one positive going and the other negative going. This produces a variety of waveforms as the two computers phase drift.
