Yes I know that is a digital analog converter but technically is it working or not.
I mean if I leave alone the RCS there is still 7 potentiometer in the FLCS+TQS.

But if I can use MCPchip than I can reduce the wires number.
Can I mix them in the MCP chip? the 4 analog potmeter in the TQS handle. can I use the same MPC chip with the Z-axis TLE5011?

The problem is , doesn't it matter how many potentiometer can connect on the arduino if the windows can handle only 8 axis?
because If i can save some pins for another potmeter or shift register then maybe I can add more controller inputs /outputs there.
I just want to make it only once and after that use it simplest as I can. If I use only one arduino for everything then I have to set up only once and only one USB connection.
