This question is similar to a previous one from me however I think maybe I was not clear on my applicaton.

What I need to do is take the step and direction signals, being generated by sofware and output to the LPT port on a PC, and use those to generate either a PWM signal or an Analog voltage output of +/- 10 VDC which will be used to control the driver/amplifier(s)for DC servo motors on an existing CNC router. I was hoping that this could be done with the 8052-BASIC or even with assembly code using and regular 8052. It would not be objectionable if a dedicated system were required even though I am already using an 8052-BASIC for the PLC on this machine.

Any help will be GREATLY appreciated.
