Hi,

i am trying to use an 8 channel adc for a university project. I have been unable to get the raspberry pi (3b+) to see the adc hat. When i check the i2c busses (0, 1 and 2) i am not seeing anything that resembles the i2c addresses i have set (i have used the default ones 0x68 and 0x69). I am using a lipo battery hat and a 5 inch touch screen.

when i try to do i2c detect on bus 0 and 1 i get no addresses but bus 2 has 3 adddresses but none match (5f range).

when i try to run the library i get a remote i/o error and self bit rate and self address error highlighted. I have tried with a fresh install of the latest os with no luck.

Hi

Have you enabled the I2C bus on your Raspberry Pi?  We have a tutorial for enabling I2C on the Raspberry Pi, which goes through the necessary steps to use the I2C bus.

The ADC Pi should appear on I2C bus 1.  You can check the bus using "sudo i2cdetect -y 1".

If the ADC Pi does not appear after enabling the I2C bus, try removing the touch screen and battery hat in case they are causing a hardware conflict.
