I was doing some searching on the forum and found several threads that detail on how to setup the software PWM for use. But i couldnt find anything on how to use the hardware PWM in B4J. So, how do you use the hardware PWM on B4J? I need something around 18 to 20Khz frequency with at least 8 bits of resolution but not sure if the Pi can do it. I know the software pwm cannot....

pi. The LED stripes can be dimmed with PWM so I first tried to use jPi4J library with software PWM... pwm uses a very low PWM frequency. A test on the hardware PWM port of the raspberry pi was much better. So I decided to order the ADAFruit 16 channel PWM board for the raspberry pi which has 16 hardware...

I use the forum search to look for "rpi pwm b4j" several pages came up. Erel had a post from 2014 that described this. The dimmer board is controlled by one i/o pin and on pwm pin from the rPI. You should be able to getting it working with the rpi....
