Hello everyone, I have a small problem with SPI communication. I'm using NI USB 8452 module and LabView 2013 with driver NI USB 845x 14.0. As a first step I ran the example from attached library called "Atmel AT25080A Write.vi". The problem manifests as logic "0" all the time on MOSI and MISO lines. No Data transferred. CS and CLK works properly. I never use pull ups when using SPI but maybe I should? The question is did anybody meet the same problem while using this usb 8452 module? All 4 SPI lines connected directly to oscilloscope. Waiting for any reply. Thanks in advance.
