Dear everybody,


in an ongoing project I have tried to rebuild Circuit Note CN-0129 to create a range extended measurement system. For this purpose I have ordered a demo board for the AD7746 to allow USB-to-I2C communication and have a helpful Windows interface to set-up my etched board. For testing purposes I designed the board exactly as mentioned in CN-0129 and attached this board with a sensor to the demo board. However now I am struggling to set the write values in CH-1 set-up to see my sensor work properly. Please find a screenshot attached!


What am I missing?
