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
