Hi Charlie,
Thanks. The driver worked great! I compiled it and tested it with the
provided example and it worked fine.
I am thinking about adding a feature where you can set the sample rate
to 0 which indicates that you just want to poll. That is, only get a
single sample on a read - no interrupt processing for that channel.
Also, I need to set the voltage range from an ioctl.
Thanks again!
