I have used the Adafruit's simpletest.py to test out the MCP3008. The supposed result shows '0' for channel 2-7 and '0' for channel 0-1 if touch sensor is untouched.

However for mine, the returned result shows random numbers for all channels if touch sensor is untouched. If touched, it will return 1023 for channel 0 and random numbers for all other channels.

enter image description here

Is this normal?

EDIT: I have managed to successfully resolved this issue. what i did was ground all the inputs that are not used. thanks all for your help and contribution :)
