(I had so much luck with my previous "CBP" query, that I think I'm going to keep this up). Many SoC's have general purpose PWM controllers built into the device. What are the current best practices for accessing PWM controlled external peripherals (such as motor drivers) from within a real-time Linux thread? Do folks primarily access the PWM peripheral via the /sys/class/pwm interface as described at https://www.kernel.org/doc/Documentation/pwm.txt? Doesn't that seem terribly inefficient? Do folks write their own "motor control" driver and run them in kernel context? Although RT-Linux patches will undoubtedly help this sort of approach, doesn't that sort of defeat the purpose of real-time Linux (running real-time code in user space threads)? Do folks do something completely different? Again, thanks for tips & pointers. Stay tuned for my next episode, to be entitled something like "Current Best Practices for Counting External Events in real-time". (I'm still working on a less wordy title.) --wpd -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
