I'm thinking about completing some work I did with AVRs and Modbus by 
making an adapter that has a Modbus port for a PC connection, with 
digital and analog IO for VFD control. This could allow one to add 
Modbus control to a VFD that normally only has keypad or button and 
potentiometer control. If there is any demand for such a thing, I could 
have some boards made, otherwise I'll just hack together a few for my 
needs. Another thought, there are cheap VFDs with Modbus that could be 
had for not much more than the adapter would cost. Any thoughts?
