The user is trying to read and write to the AD5272 variable resistor using the CP2112. The AD5272 has a 7-bit slave address (01011XX, where XX is determined by the ADDR pin). To write to the RDAC register, use 0x100 to move the wiper to 1/4 full-scale. The user should refer to Table 11 and Figures 43-45 in the datasheet for more details. For LabVIEW integration, the user should consider using the EVAL-AD5272 evaluation board or refer to the provided FPGA and Linux driver resources.
