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. Thanks :)
