Hello guys,

I got a question regarding changing speed of a generator using Woodward governor 8290-185. Please refer to page 9 of the following document at:

http://www.woodward.com/WorkArea/DownloadAsset.aspx?id=2147484726.

Pins 7 and 8 are used to change speed of prime mover through a potentiometer. My concern here is whether I can take advantage of these two pins to change speed of prime mover by supplying a variable low voltage at those pins using a MCU (Microchip DSPIC 30f5013).

P/S: I know there is some sort of digital potentionmeter, but it's not available in my country.
