Capacitive Touch Slider

[Kova]

Hi all,
I want to build my first capacitive touch pic-project .
I read a lot of pdfs downloaded from Microchip (in particular AN1250), I want to handle the capacitive touch slider.
At the page 13 of AN1250 microchip sheet, there are 4 equations.
In CCS there are the "touch functions", but I want to know how I can obtain in CCS the values "Captured Left Base Capacitance" and "Captured Right Base Capacitance" that appears in the Microchip sheet.
And Current left and right values are 0 for the first iteration and "left and right position values" for the 2 to n iteration?

Some advice for the circuit/printed scheme?

Sorry for my english :-)
Bye

Nobody?

I have not used this, but reading over, it looks like all they mean by
Captured Left Base Capacitance is the A/D reading. Do the A/D
conversions and save them for the equations.
