Rather than build, have you considered buying a standard HMI? Most of them will handle Modbus and other standard protocols. Let someone else do the interface work, especially sourcing the actual display. Robert -- Posted via a free Usenet account from http://www.teranews.com

We are looking to develop a flexible front-end to a device, and are
thinking that an SBC(sorry, I mean PC/104, I mean embedded PC, I mean CoM,
I mean I HATE this terminology in our field) would be a good platform. 
Basically it will just control GUI functions, and then instruct a
dedicated board what to do.  We are looking at character and graphical
LCDs, but I think our max resolution at this point will be 240*64,
probably controlled by a T6963C.  We have been looking at Xscale boards
(compulabs, phytec), ARM (embeddedarm), and even some offerings from
Advantech.  I think WinCE will be the OS of choice (I know, I am the worst
person ever).  So I am wondering what the best way to control these screens
will be.  I assume I am relegated to writing my own driver out the GPIO
that these boards offer, but am wondering if there are some other common
methods?  Has anyone used something similar that supports a T6963C or
similar?
