Hello hooovahh, Thanks for your reply. I use the DAQ card because it is there. I have found no reason why it should not go with the DAQ card. If it does not work I'm going to implement the Arduino. Unfortunately, the question remains as to why the current approach is not working.

hello, I try with the DAQ card PCI 6220 via the digital outputs LINE0: 2 (CS, SCK, SI), the digital potentiometer MCP 41XXX over the SPI interface to control. Unfortunately this does not work. I have a Vi to created the digital signals (picture) and another Vi to output (picture) them on the DAQ card. Phase and polarity of the SCK clock can I change. Unfortunately, the potentiometer can not be controlled with this program. Has anyone a Idea where the problem might be? Thanks JimPanse
