Hi all,
I've done a bit with serial comms. before with NI VISA, but have a more basic question about what codes to send to my digital potentiometer. My pot is a MCP4161 with 256 settings for the wiper. The documentation shows the picture below.
It looks like code "100h" accesses the last resistor (N=257) and code "00h" accesses the first resistor (N=0).
Can anyone point me in the right direction to figure out everything in between? haha .... help a noob out here .....
Or, perhaps there is some LabVIEW SPI module that is designed to work with such a device? In the past I used NI VISA to talk to a RS-485 device.
Thanks for your help!
PS. link to data sheet, see Section 5 for the wiper stuff https://www.mouser.com/datasheet/2/268/22059a-51937.pdf
