What are the key differences between Echelon's ShortStack and FTXL products?

Both products are used to add a LonWorks interface to a host processor. The FTXL solution supports a series of FPGA-based host processors from Altera, where the ShortStack solution supports any host processor with sufficient resources. The ShortStack product requires fewer resources on your host processor in terms of program memory and RAM. The two products use very similar versions of the LonTalk API, providing familiar interfaces for developers who require both solutions in their product lines. The ShortStack Micro Server supports up to 254 network variables on the host, while the FTXL solution supports up to 4096 network variables. The FTXL solution also has a higher performance LonTalk protocol stack since much of the protocol is implemented on the 32-bit host.  more
