Hi, I’m trying to catch an initialization sequence on SPI bus but constantly fail to trigger on the start of the communication. I use the latest PulseView on windows and a cheapo Saleae clone.
Triggering on CS works fine when communication is repeatedly querying on the SPI-bus. Don’t know whether it is relevant, but I use a Nucleo-L4R5ZI and a Arduino Ethernet Shield 2, which basically is a W5500 chip. In the hope to rule out bad software, I use the Arduino-provided WebServer example in Sloeber (eclipse-Arduino IDE). But the behaviour is exactly the same if I use standard Arduino IDE. The W5500 is constantly polled for incoming TCP/IP communication and I have no problem capturing this by setting a falling trigger on the CS line. But if I want to capture the initial SPI communication by holding the µC board in Reset, hitting the run-button in PulseView and releasing the reset button simultaneously. I very, very rarely get a trigger event and consequently no data. Maybe every 100 tries I get a trigger. Since I am new to using PulseView, I wonder if I might be using it in a wrong way… Cheers, Bob
