Hi all,
I want to build my first capacitive touch pic-project (I use the CCS C compiler, latest version).
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....Do the "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
