x115 Trigger?
Posted: Wed Jan 19, 2022 11:19 pm
Hi, I'm trying to get a BladeRF x115 device to capture a set number of samples when an external trigger (via J71) is pulled low. Unfortunately, it seems like the trigger must be pulled low for a long time for the trigger to fire (60us low pulse doesn't seem to work, but if I maually force it low for 50ms, it's fine - or if I repeat several shorter pulses, it's fine).
Is this expected behaviour - is there some minimum length of time the trigger must be low for it to work, and if so, what is it?
I'm using the latest FPGA hosted image at the time of writing, and bladerf-cli (using slave.txt from github sync_trx directory, removing the smb_mode line, assuming there's some kind of internal default clock).
