Subject: Looking for small form factor with HDLC
Date: Mon, 19 Nov 2007 16:20:21 -0800 [thread overview]
Message-ID: <CDD877E4B771FEED28BF8BF5@[10.170.7.6]> (raw)
I'm attempting to create a middleware system that talks to one of my
vendor's motion control products. My vendor has an FPGA capable of perhaps
10 megabit performance, and RS485 full-duplex tranceivers. I want to be
able to send commands and receive events and bulk data efficiently. I'll
also add electrical isolation, possibly with suitable 485 transceivers.
I'm thinking that HDLC is a natural fit for the bit-level protocol, so I'm
looking for an SBC and Linux OS with natural HDLC support. Ideally the SBC
would fit in a 3"x3"x1" volume, and include Ethernet. It will go on a
backplane along with the motion control box.
The Freescale chips look like many have the hardware to do HDLC, so I'm
wondering what's available for boards and drivers.
