Acs712 current sensor

I was wodnering if anyone has any experience of using the acs712 current sensor with the mangOH boards. I have it connected to ADC0 but regardless of whether the AC is connected or not the reading is the same.

I’m somewhat stuck and running out of ideas now. I did a cm adc read EXT_ADC0 and I get back a count response, but this count value doesn’t change. I was wondering would I need to enable GPIO33 (CARD_DETECT_IOT0) in order to get ADC0 readings and if so how would I go about doing this? le_gpio_Activate doesn’t seem to take any specific inputs to specify specific inputs.
