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. _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
