PIZ-Up Time not showing with i2cdetect


#1

I am trying to use this HAT with a pi zero w.
I have attached the hAT and inserted a battery.
I have two LEDs on the front and a blue showing on the back.
I have installed the software and amended the rc.local file as advised.
But i have the following errors.
i2cdetect shows blanks (i2c is enabled)
Running Pi-16ADC.py gives Error 12 Remote I/O error.
How can i trouble shoot this and how are the LEDs to be interpreted.
