Visual Basic 6.0 Motor (PWM) control via a Joystick to basic Stamp Micro

Hello all 
I am presently working on a robot project and I·thought I might·ask a question before I start my next battle to win the war with my design.· I am attempting to control PWM with a Joystick via VB 6.0 and send those commands with a Xbee Zigbee RF module.· The IC Chip I bought for the H-bridge motor control was the SN754410 (Quad Half H-Bridge IC), but I have overlooked the fact this chip does not have an input for PWM.· I am able to manipulate the buttons and XY coordinates of the Joystick and show the results in text boxes and·labels in a·small VB program, but·I am a little confused
on manipulating X ( 0 through 65,535) and Y ( 0 through 65,535) coordinates to PWM.· Something tells me I have to scale.· Do you think this would be too much trouble?· And would the Parallx H-bridge motor controller automatically do this for me?· Thank you for your feedback.

Parallax H-bridge motor controller? Do you mean the HB-25? If so, then it will not scale for you. It is a great motor controller, though. (No Parallax motor controller will perform scaling, as far as I know. However, I may not know too far.)
Do all the math in VB6.0 and send the Stamp what it wants to see so it can easily send it to your motor controller. If you have a PC and VB in the background, let'em work for you.
