pps triggers rx

Post by KE8NDP »

Hello, I would like to start an rx collection when a pps signal is recieved by the bladerf. Im not sure how i would start to do this. Can the trigger functionality be used to this or will there need to be changes to nios code? Can the nios code look at the trigger registers? I am a little bit confused on the internals of the trigger functionality. Any guidance would be appreciated.

Hello, which bladeRF are you using?
For some documentation on sample triggering and using the trigger command in bladeRF-cli please take a look at the following Github page: https://github.com/Nuand/bladeRF/blob/m ... /README.md

I am using the x40. I get that the triggering functionality is meant to work from a second bladerf but can it work from a signal from an external device? How is the triggering implemented internally - can I get a consistent latency between the time the trigger is fired and the start of the collection?
