I tried interfacing with MCP4901 8 bit DAC with arduino using LIFA tool , but it is not working any suggestion , please. i attached the file .
What behavior are you seeing when you run the VI? Are you not getting any data back? Not the correct data? Error messages? I took a look at the VI and everything seems to be set up correctly.
if i run this VI i will get data all clocks and data and CS signal coming in the pins of Arduino UNO perfectly . no error messages
If all that is working what aspect of your design are you having issues with?
all looks fine but no output from DAC4901 , may be i am missing some byte order ,i need to check the datasheet fully .
