hi...
i am working on a project called touch switch...i am using QT600-ATTINY88-QT8 evaluation board...i am enabling two keys...and using those keys.... iwant to toggle portd3 and portd4 for GET_SENSOR_STATE(6), AND PORTB6 and PORTB7 for GET_SENSOR_STATUS(7)......can anyone please help me..why it is not detecting....here is my code...
