I've been looking for a "Modbus TCP" implementation inside an application working with BF537 + VDK + lwIP.
I found http://www.freemodbus.org/index.php that seems exactly what I need. They say this library support a generic lwIP port.
Has anybody successfully tried this library with Blackfin processors?
Or is there an easier approach than can be used to implement "Modbus TCP" on Blackfin?
