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. <br>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.<br>Thanks :)<br><br>Sent from my HTC<br><br>----- Reply message -----<br>From: "Jonathan Neuschäfer" <j.neuschaefer@gmx.net><br>Date: Sat, Oct 6, 2012 10:29 pm<br>Subject: Gpio interrupt shall pass the signal to application<br>To: "jeshwanth Kumar N K" <jeshkumar555@gmail.com><br>Cc: "kernelnewbies" <kernelnewbies@kernelnewbies.org><br><br><br>On Sat, Oct 06, 2012 at 01:50:55PM +0530, jeshwanth Kumar N K wrote:<br>> Hello All,<br>> <br>> I am writing a kernel module that shall pass the signal to application running in user space.
