I have added better exception handling to the ADC Pi class so it should hopefully give you a more accurate error message when a problem occurs. I have also added functions for setting and getting the i2c addresses for the two ADC chips. The new functions are called set_i2c_address1(address), set_i2c_address2(address), get_i2c_address1() and get_i2c_address2()
The most common cause for problems initialising the ADC Pi is an issue with the I2C bus. Try checking that the ADC chips are visible on the I2C bus using the command "sudo i2cdetect -y 1". i2cdetect should return a list of detected I2C devices on the bus. The ADC Pi will normally appear on 0x68 and 0x69 unless the address header has been changed from its default jumper positions.
If the ADC Pi does not appear on the I2C bus try going through the steps in our I2C tutorial to check that the I2C bus is configured correctly.
