Hi Charlie,
any chance you would like to post the ported version of Phil's 2.4 driver. I've
been using the latter for over a year and I've written my control logic using
it.
porting and testing it is a human resource drain I was not looking forward to.
Since you've already ported it, it would be a great not to need to reinvent the
wheel.
TIA, jacques.
