I want to thanks the three of you who responded to my plaintive cry of woe....

After careful consideration and further purusal(sp?) of my PBP Manual.....

I happened upon the wonderful 'I2CWRITE' feature! This little gem coupled with an Analog Devices I2C 'digipot' will allow me to use the 2.5volt reference included in my Laser Diode driver to set the Laser Diode Current output to whatever my heart desires!

Were I to use the PWM method, I'd have to worry about the DC Supply (NiMH battery) changing over time as it surely would due the large amount of current I will be drawing to power my Laser Diode.

I will look into to the reference option though....that might be worthy of future consideration!

Thanks Again!
Robert
