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.

I am trying to read and write the variable resistor of AD5272 through cp2112. The function module of cp2112 has. I don't know the slave address of AD5272.
The AD5272/AD5274 each has a 7-bit slave address. The five MSBs are 01011 and the two LSBs are determined by the state of the ADDR pin. Please refer to Table 11 and Figures 43, 44, 45. Pages 18-20
Since the slave address is 0101111 with 7 bits, is it 01011110 when inputting as an 8-bit value? Is 5E correct with the value as the hex value? In Table 13, write 0x100 to the RDAC register, wiper moves to 1/4 full-scale position
How do I enter the command value?
How do you enter the values of DIN and SDO? p.s.
Which function should I use in the cp2112 library in Labview?
