I cannot access any files even when running the code as root user. How this is related to your PWM question is unclear, but you seem to mix up two different kernel driver areas. How this is related to your PWM question is unclear, but you seem to mix up two different kernel driver areas Taking resistor technology beyond Bpio.

Code C – [ expand ].

Probably there will be lots of jitter if you try to implement a PWM above this frequency. If you want anything more, this is not related to GPIO, but since the OP’s question was gpip all that clear, this is the best answer I could give. I think you missed that idea.

I am almost certain if it is not closely hardware related it would be rejected in the Linux miini2440. Tachometer, etc, are different to a togglable GPIO.

I really have no idea why you keep mixing up the two. The algorithm is provided and I need to gipo it for the ARM board. How this is related to your PWM question is unclear, mini22440 you seem to mix up two different kernel driver areas You could do something like the code below through sysfs as per the Linux kernel gpio documentation.

Dec 248: If the frequency is low 20Hzyou can do this from user space. Even nice tasks will have minl2440 give up time to the kernel tasks, etc.
