I am trying to interface to an AD5593R. I need 3 channels of conversion at a sample rate of 96 KHz per channel. I am using Python 3 with the following commands:<write_i2c_block_data(address,cmd,vals)> and <read_i2c_block_data(address,cmd)> . I get a result, but no matter what I input to the different channels, I always get the same result, no change. I can read the device address okay. I tried using several write commands and one read command, but no success there. I am not experienced in this area. Can you advise on how I should set up the parameters for the commands?
