Just for you info

further testing of the CTMU for my project showed that the adc reading on the CTMU changed a great deal when the programmer was connected to the pcb or the USB to TTL converter , when connected to the pcb and PC for value of the readings

this through out the " touched" level ADC reading by a factor of 1500 ( 12bit ) .

when setting the " touched level " for what the switch is changing , i would highly recommend isolating external earths that may not be there when the unit is running , when setting your trigger level for the fuctions that the touch switch controls


cheers
