Hi,
We are using drs4 board, but oscilloscope app will somehow stop to work if we config trigger into "or and", When I look into the drs4 firmware file drs4_eval3_app.vhd, I couldn't find the trigger_config value assignment which is mentioned at(#7 offset 0x1E from 31 downto 16) in manual_version 4.
could you help me find this trigger_config access point?
thanks

The "and" in the trigger section means now "coincidence". So the V4 board can trigger on a coincidence between two or more channels. If there is no pulse at the same time on the coincidence channels, the board will of course not trigger. The according firmware was introduced in V4, so please look at drs4_eval4_app.vhd (not eval3).
I just realized that the V4 firmware might be missing in the distribution, so I have attached it here. Look for drs_ctl_trigger_config.
Best regards,
Stefan

By the way, will there be a drs4_eval4.vhd as well? |
