Re: Gpio interrupt shall pass the signal to application

Actually what I am doing is, I have 3 inputs to beaglebone from BLDC motor hall sensor. If there is any change in any of 3 inputs, the kernel module has to send signal to my beaglebone. From the interrupt my application reads the input from sysfs and pass the next sequence to pwm. PWM I am using userspace only. So is my design right for handling fast input change, I mean 50 micro seconds ? Any suggestion ? I am new to device driver concept, please suggest.

Hello All, I am writing a kernel module that shall pass the signal to application running in user space. So which signal i should use? And how to achieve this? Thank you.
What kind of information need to be transmitted from your device to the application? Jonathan Neusch?fer -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.kernelnewbies.org/pipermail/kernelnewbies/attachments/20121006/bf6bba1b/attachment.html
