pb with Digital Discovery too sensitive to glitchs on CSelect

[samuel.cregut]

I'm trying to log SPI communication between 2 MCUs (2 Arduinos UNO).
The communication is good (UNO2 receive the byte from UNO1) , but the DigitalDiscovery is not able to decode MOSI signals because it seems that there are glitchs on CSelect signal (as shown on the picture bellow)

Is it possible to tune the DDiscovery in order that it is less sensitive to these glitchs (or do i have wrong use of the DDiscovery like bad DIOs?).
  

best regards

Hi @samuel.cregut

Make sure you have good ground connection between devices and the digital voltage is set to proper value, twist signal wires with ground...
