SPI - SDIO Decoding bug

Post by jurke92 »

Hi there!

I am using PicoScope hardware and software (7.1.2.15463 T&M Stable) for decoding of one protocol. I am using default decoder (SPI - SDIO) and I have found out that for some reason some bits are not sampled on the correct clock edge. I have selected clock rising edge as a reference for bit sampling which means that bits should be sampled on the falling edge- However I am experiencing that some bits are sampled on the rising edge like shown on attached picture.

The bits in the decode appear to be sampled on the rising clock edge, please check the clock edge setting in the decoder setup

If this doesn't resolve the issue can you please post a psdata file so that we can see the data and the setup.
