Hey. A few months ago, I decided to connect the DS2450 ADC to the Omega-2, but my experience has shown that it is better not to do this.
The problem is that Omega-2 sees this, but cannot read the data. For the DS18B20 temperature sensor, this works, because it is easy to control, but the ADC is a more complex device.
I wrote in several forums, in Onion technical support and in Maxim Integrated (Dallas Semiconductor), but they all said they did not know how to solve this problem.
In the end, I got rid of the problems by replacing the DS2450 with ADS115.
