Hi all, we would like to use the Friendly ARM dev board for controlling an autonomous robot and avoiding obstacles and stream live video using a webcam. Are there any recommended real time operating systems that still preserves the BSP and available libraries and packages Linux offers? Secondly, I'm still fairly new to this embedded linux thing. I looked at the sample pwm code provided and I noticed that it opens the /dev/pwm and calls ioctl based on this file. Can anyone point me in the right direction on where or how the register config bits are set, where the documentation for these functions are, such as using ioctl ,and how to select the pwm channel, frequency and duty cycle etc etc etc? many thanks!
Driver (PWM) and Real Time Applications
I created a pwm driver to use with gpb1. At my code has comments to help. Look in datasheet and compare with the code, is easy to understand. http://www.friendlyarm.net/forum/topic/4932 Good luck.
Hi Uilian Is this driver compatible with 3.xx kernels. Sample user space code? How do I integrate this driver with my kernel? thanks --fatbrain
