Apparently, pwmgen mixes both PWM and PDM in the same signal. The man page indicates that for pwmgen.N.pwm-freq "A value of zero produces Pulse Density Modulation instead of Pulse Width Modulation". I found that for my settings a 50% input produced the highest frequency of 10kHz before the pulses started running together. For the C11, I don't know if it would interpret a short on pulse with a long off time the same as a frequency with equal on and off periods. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
