Using the OAK PSRBS Cable for FS_IN 4 Lane Syncing

Nearpoint

I found this in the docs

About the:
FSIN_4LANE - 4-lane MIPI FSYNC signal input/output

If I use a raspberry pi pico and program is to send pwm signal for 60 fps to pin 6 using the PSRBS cable and connect gnd to gnd, that would drive all four cameras if I set there frame sync mode to INPUT for all connected cameras? Is it true?

Hi @Nearpoint
I think it should yes. But make sure to manually enable the MXIO42 to connect the A,D and B, C lanes together.

Thanks,

can you clarify

"manually enable the MXIO42 to connect the A,D and B, C lanes together."

do you know the software code that ties the GIPO pins together? The code found in the hardware sync example docs

Hi @Nearpoint ,
Yes, that example, to just toggle a GPIO. Or this example (auto-detect revision):
