[time-nuts] FE-.5680A trimming resolution

[Javier Herrero]

I'm now gathering the unit self-updating of DDS data, that will take 
somewhat long... so I will try later or tomorrow. Since we have seen 
that the DDS values are reported back in a response to a command, it is 
easy to do without the need to have anything hooked to the SPI bus :)

Regards,

Javier
