Hi Guys
I was just looking for a replacement to my QT320 IC, i came across the PIC16F726, this pic has a capacitive sense module built in.
Has anyone ever used flowcode to use this feature??
Can flowcode even be used to make this feature work?? I need to 4 keys to replace what i have already.

Have you tried selecting PIC16f726 device?
I did not think flowcode V3 supports that device?
Thought it was only flowcode V4 that does?

V3 doesnt have the 726, but if i know i can make it work on V4 then i would probably buy v4 to do the job on,
I have seen other people use chips like 16f610 and 16f887, but i dont understand how they do it.

just been reading that this can be done using adc, using the internal capacitor.
Anyone got any idea how to make this work in flowcode??

Hello,
Yes this is possible using only an ADC input and maybe also a timer interrupt.
Here is an app note from Microchip detailing how to do it.

And here are the files from the app note.
