CDS need help

Postby burningmosfet » Thu Oct 06, 2011 5:50 am

Dear Sirs, I'm a not a newbie in programming mcus but i'm new to cypress sigma delta capacitive touch. I'm trying to build a capacitive keyboard using CDS block on a CY8C21434. I configured the [Pinout ] section and the [chip] section. I'm blinking 4 led at the startup and here all is ok but the capacitive pads doesn't work (they should turn off led when a key is touched). Here attached my project and part of schematic, I would be very grateful if someone with more experience than me could give some advice. Best regards
