How to set multiple triggers in logic analyzer?

[chiznut]

I'm using the logic analyzer in waveforms beta v3.20.14 on an Analog Discovery 2. I have 3 barometers on an SPI line and I'd like to look at the data output from each one in real time. Commands are sent from a microcontroller and data is read from each one sequentially every 9 ms, but each transaction only takes about 50 µs so I can't set the time division to something wide enough to see all three transactions and still read the data. I tried creating 3 windows using the select line for each barometer as the trigger (see attached photo), but doing this only allows me to see the data for one barometer at a time. Clicking run in one window stops the other window from running. Is there any way to get all three windows running at the same time?

Hi @chiznut

Only one interface can control a specific device instrument at a time.
You should add all 3 SPI interpreters in one Logic Analyzer and use 4th device configuration which has more buffer Logic and/or use Record mode to capture even more data.

Hi @chiznut

The next software version will support multi chip-select in Protocol/ SPI/ Spy
