How to use HarpSyncInputDevice
?
#15
Comments
ONIX is not a harp-compliant device, as it does not alter its timestamps in sync with a HARP clock generator. ONIX does create its own high-resolution timestamps that are used to synchronize acquisition from all devices connected to it. The HARP input device is a way to input HARP timestamps and synchronize them with the high resolution ONIX frame clock. Basically, every time a HARP clock timestamp generated by a clock generator is received (once every second) it generates a frame which includes both the HARP timestamp and the ONIX timestamp of the precise moment of reception. This way, a relationship between HARP and ONIX timestamps can be created to align events. |
I must have connected something wrongly as I don't see any output of HarpSyncInputDevice. I have a Harp clock sync device that I use to generate timestamp. One of the output of this device is connected to the clkin of the harp timestamp bus to SMA board. The board is connected to a random USB port for power (different computer). |
Ah, sorry for the confusion. The HARP device reads from the I1 port on the host. |
I'm trying to see what is currently possible in term of harp-onix synchronisation. I got some of the hardware part sorted I think (here https://github.com/orgs/harp-tech/discussions/19) but I'm not sure about what is implemented already on the Bonsai.ONIX.
Is the
HarpSyncInputDevice
already working? And what does it do? :)The text was updated successfully, but these errors were encountered:
