OK Ben, Go to rswww.com. You'll need to register, which is free, and thenBR said:Please?
Thank you.

The schematic in the paper you referenced shows how:BR said:Ok, I need to control one Servodisc motor. The H-bridge for the motor has a
voltage input that controls the PWM. It also has two ports for forward and
reverse signals. I was looking around and found a simple schematic for an 8
bit d/a (AD7524) which is apparenty nothing more than connecting the 8 data
lines of the parallel port to the DAC. Now I may just try getting along with 8
bit resolution, but if I need more resolution, how do I load two bytes into a
12 bit DAC? (realizing that 4 bits will be discarded). I will probably figure
out this simple project myself eventually, however perhaps there is a way I
could be prevented from using more chips than necessary to accomplish this.
Help appreciated.
