Hi Damiafix.
Ah, the English.
Resolution FMX-1 is 256 units, because this is the data width 8byte (D0-D7).
Leave 2.2Kom is OK.
There is no need to use the switch to him.
The best is the logarithmic characteristics of the R6.
The worst characteristic is exponential because the too fast growing.
When you have a linear potentiometer R6 is just 2.5 Kom.
Best regards Chris.
