Hi,
Currently I'm using an L298 to drive a couple of DC motors. Unfortunately
the only way I can intorduce any sort of speed control is to PWM the enable
line since PWM'ing the inputs for speed control does not work.
Does anyone else know of any other chips that are good H-bridge chips that
can be used for speed control? i.e. They can take a PWM'd input that will
increase/decrease in speed depending on the duty cycle?
Thanks

| I use the L293D in my Lego Automation Controller. PWM works fine with this chip. (I built several variations of the controller before Mindstorms was available.) - pete. (...) -- Pete Sevcik sevcik@flash.net Techno-stuff Robotics (URL) for FUN ! (24 years ago, 31-Dec-00, to lugnet.robotics)
