Since the Mailserver didn't seem to broadcast the following mail, i resend it now. BTW: Somebody should check the CPU-Fan of the mailserver :-) Bernhard
Hi! I have done some timing critical pulse width modulation examples. Maybe, they could be usefull for somebody else ... PWM-Demos: ---------- Due to the excelent timing-facilites of RT-Linux, it is possible to do very timinig critical things in software, where normaly special and expensive hardware would be needed. Here are three examples: pwm: Pulse-Width Modulation for controling up 12 DC-Brush motors directly via Parallel-port, with 1000 Hz base frequency. pwmsound: Pulse-Width Modulation for playing sounds over standard PC-Speaker with a base frequency of 16 KHz, 2-times oversampling (parameters can be changed when loding the rt-module). servo: Special Pulse Width Modulation for controlling up to 12 Radio Control Servos directly via the parallel port. The code should be just ok, but the documentation was written very fast, so that there are many mistakes, but i wanted to have the things published so that others can play around with it ... :-) Author: B.
