    PWM below 4Khz

    I have been reading old posts from ANJ and Hippy about altering a TRMS prescale register to get lower PWN frequencies. I have got together a working set up for controlling a power feed on a workshop item using info from several contibutors to this forum and this lower frequency thing would just...

    18x to drive stepper power feed

    Following my previous post, I have progressed my power feed controller using an 18x and the PWMOUT command. The motor will quite happily start from scratch up to about 140 rpm and I have managed 160 rpm on occasions.However, I am told that I need to program in some form of ramp-up and ramp-down...

I have a large stepper motor (7.8A) and its proper commercial driver but to control the functions I need a few basic inputs and a variable trigger pulse to feed to the driver. I am fairly new to PICs and not sure of the way...
